What is Karcher RM111?

KARCHER RM111 ASF: PressurePro Machine Protector Advance 2

Karcher RM111 ASF is designed for hot water pressure systems between 60° – 150°C that are supplied with soft water. If purchased along-side your Karcher machine or Pressure Washer which can implement RM111, it is advised to use it from the get-go as it protects against rusting – In the long run, this simple affordable product could cut costs on servicing and maintenance repairs.


Effective protection against calcium deposits and corrosion in hot water high-pressure cleaners. Also provides care for the high-pressure pump and protects against black water (corrosion of the heating coil caused by particularly soft water, which is then disposed of out of the lance). Reliably effective in all-water carrying parts, guaranteed to be compliant with the device and easy to separate (ASF).


Similar to Karcher RM110: This chemical, which is neutral 7pH, is run through your machine in small doses by Karcher’s integrated technology or via an implemented system on your pressure washer to prevent rust from occurring.

Condition : New

Aqua Blast Systems have a soft-spot for Karcher HDS 6/10 machines due to their pure excellence in performance. This machine is our best seller and our recommendation to customers as this model performs well in the majority of application: Vehicle Cleaning, Equipment and Machinery Cleaning, Workshop Cleaning, Outdoor Area Cleaning, Service Station Cleaning, Swimming Pool Cleaning, Production Processes and Systems Cleaning – The list goes on! The Karcher HDS 6/10 is an all-round favourite.


Firstly, Aqua Blast Systems reflect that this machine has the least repairs carried out due to its versatile technology and hardened construction. Such as The Soft Dampening System (SDS) which compensates for vibration and pressure peaks in the high-pressure system. Therefore, off-loading strain from the components of the machine and essentially protecting them, potentially money-saving technology. The SDS also protects the heating coil against calcification damage: a build-up of limescale which can cause your pressure washer to malfunction. However, if for any reason your machine proceeds to construct deposits of limescale, you can run Karcher RM110 chemical through it to break-down and dispose of calcification. Aqua Blast Systems recommend using RM110 from the point of purchasing your pressure washer as Warranty must be in conjunction with RM110 or RM111 Chemicals.

Appropriately, due to the vast areas this machine can be operated in, the HDS 6/10 comes attached with; an industrial heavy-duty, low-speed motor functioning at 1,450RPM, so you can rely on your motor not getting overwhelmed as it manages its load with ease – Giving you peace of mind of machine break-downs.


What about the pump? Manufactured with excellence, this model is equipped with a three-piston Axial pump unit where ceramic pistons are consumed, considering their extreme durability and intense resistance to damage and wear, completely understandable. Additionally, implemented variable pressure control is accessible from the pump head to adapt to cleaning projects, the operator is in control at all times.

Another great feature is the Leak Detection System, which has multiple benefits, the leading one being the protection of machine and electronics. For example; If you had a leak in a coupling or seal within the unit, this particular model will shut down altogether and alerts the operator on the controls that there is a leak. Overall, protecting electrics and components from water damage. Another benefit being the prevention of floods, if for example, you use your machine in a stationery area, on different pressure washers the machine would usually continue to leak and operate at the same time – obviously longer durations means more of a flood. This model cuts the machine off and water inlet to stop this.

The machine is supplied with a stop and start system, which has the ability to cut the power of the machine when operators leave the unit running. Leaving pressure washers switched on and in motion can seriously damage and destroy components by seizing up or burning out. This small, yet significant feature prevents this.

Technology is at the heart of this pressure washer as its incorporated Exhaust Gas Temperature Limiter, which does as it says on the tin: monitors the temperature of exhaust fumes from the machine. This is an amazing feature which consists of a probe in the chimney with sensors and terminates the burner if it ever gets dangerously hot.


Karcher HDS 6/10 Overall is an amazing pressure washer which should achieve most cleaning projects. It has optional additional attachments which can improve performance, and chemicals which can reduce the effort required.

How to Stop Limescale in my Pressure Washer | Calcification


Calcification in terms of hot water heating systems can be problematic. Limescale is a hard, stone-like, chalky substance which collects within hot water systems due to the presence of calcium carbonate deposits, discovered in ‘hard water’.

With British weather, it’s no secret we have a lot of rain downpour. Rain plays a major part in calcification, as it slowly percolates through the soil, continues to break-down and dissolves calcium & magnesium, which is then transported through your pressure washers hot water system.


These deposits, if neglected, proceed to crystallise into chunks of calcite which establish on the surface of the system, causing a number of functional issues. Calcification is the accumulation of limescale that can occur on all types of pipe and tank material. The development of Limescale has a number of consequences for hot water systems:

  • Limescale within pressure washer system acts as an insulator, therefore, slows the transfer of heat from the heating element to the water. Wasting time and reducing energy efficiency.
  • Can cause heating elements to fail prematurely.
  • Calcification reduces the rate of water coming through pipe system, meaning the pressure of your machine will drop.
  • It can affect components within the unit such as; pump, valves, seals, spray nozzles. Impacting the safety performance of the machine.


Aqua Blast Systems advise and recommend to all our customer pre-sale to purchase along-side your machine Karcher RM110 Chemical, which prevents limescale deposits in hot water high-pressure cleaners. The new formula offers improved protection against the build-up of limescale in heater coil systems (up to 150 °C) as well as integral corrosion protection for all HDS machine components that come into contact with water.

Kranzle K 2160 TST Pressure Washer Review


Excellence in Cleaning Performance.
Kranzle K 2160 TST


Operating Pressure (bar/MPa) : 30-140/3-14
Current Type (Ph/V/Hz) : -/240/50
Flow Rate (L/Hr) : 660
Power Rating (kW) : 2.4
Power Cable (M) : 5
Dimensions (L x W x H) (mm) : 375 x 360 x 900
Nozzle Size: 042
Brand: Kranzle
Condition: New

Kranzle manufactures high quality, durable and trustworthy pressure washers, setting an uncompromising standard which results in top-notch machinery. Anywhere from the use of domestic machines for home & garden to heavy-duty industrial machines for continuous use for up to 12 hours a day!


The minuscule design may be decieving, however, don’t let that fool you! The Kranzle 2160 Model is beyond any domestic machine, although it looks like one, it has tenfold the power. This particular model is amongst the most common Kranzle Machines in circulation because of the small, compact design with powerful pressure outlet. Well respected within the cleaning industry due to the friendly price-tag between £800-1000, while still managing to keep quality industrial components within the strong, durable chassis. Constructed with genius, the chassis reflects high-quality after witnessing first hand these models taking wraith off elements of the world, yet still remaining in reasonable condition and primarily – works!

Majority of Kranzle models have optional attachments, Model K 2160 TST being amongst the selected machines. Potentially, you may need additional attachments to fully satisfy your cleaning project such as Dirt Killer Lance. Manufactured with great technology which features rotational spraying jets at a fraction of the usual angle, creating a narrow passage for the water and therefore results in more pressure. With a narrow passage of water means smaller surface area being covered, so Kranzle’s integrated technology has given the nozzle the ability to spin as it cleans, blasting a larger surface area.

To further support the K 2160 Model quality, it comes with a TST (Total-Stop) Version to protect the components within the unit from overheating, burning out, and overall, destruction of the machine. We know, being in the industry, that operators are prone to leaving their machines running (Sometimes all night!) resulting in some ‘pretty’ costly repairs… With this machine, you don’t have to worry!

TST Version also comes equipped with a hose reel. High-Pressure hoses can weigh quite heavy, so when attempting to wrap-up after the cleaning project, can be fairly difficult. To ease operation, the reel will neatly wrap your high-pressure hose for you. Another benefit to this feature, the reel protects the hose from being dragged across the floor, run over by vehicles and general damage – So it saves you money on replacement hoses too!

What is a Dirt Killer | Dirt Blaster Lance?


Firstly, there are copious terminologies for the specified lance: Dirt Killer Nozzle, Dirt Killer Lance, Dirt Blaster Lance or just “the one that’s more powerful!” – the list goes on. You are aware of the ‘bog-standard’ high-pressure nozzle which comes as standard for your machine, but what is a Dirt Killer Lance and what does it achieve?


Whether it’s Karcher, Kranzle or Dirt Driver etc, each manufacturer all use their own phrase for their powerful nozzle attachments – hence why there are so many choices of words. However, a Dirt Killer attachment is designed to cut through tough grease, grime and soil using technology which applies a narrower passage for the water outlet. Therefore, applying more pressure to the water as the Water Flow has not been reduced meaning your machine continues attempting to push water at the same pace through a smaller hole.

What makes these lance attachments or alternatives so special is that the advanced technology creates a spinning mechanism. As you can imagine, spraying water from a smaller hole channelling through until it hits the ground means that it has more pressure but it is still a smaller spraying area. With advanced technology, the powerful narrow nozzle now spins to cover more surface area with every stride yet keeping its insane pressure.

Kranzle K 7/122 TS Automatic (Total-Stop Auto) Review


Excellent, Compact, Dirt Killing Machine!


Operating Pressure (bar/MPa) : 30-120 / 3-12

Current Type (Ph/V/Hz) : 1/240/50

Flow Rate (L/Hr) : 420

Power Rating (kW) : 1

Power Cable (M) : 5

Dimensions (L x W x H) (mm) : 440 x 200 x 330



The Kranzle K 7/122 TS Pressure Washer may not look like much, but believe us when we say it Packs-a-Punch! Many people doubt the cleaning result of this compact machine because it looks like it would be used domestically. However, the performance and pressure are beyond any domestic machine; with the ability to upgrade some components for extra performance, e.g: Turbo Lance. That is why, overall, this machine is used worldwide for a lot of valeters and other industries who struggle for space within their workshop but who also need effective cleaning execution.

Aqua Blast Systems will only provide machines in which we believe-in ourselves, we refuse to sell ‘rubbish’. We provide a warranty with our machine services to back-up our confidence in the Pressure Washers we deal with.

The Kranzle K | HD 7/122 Total Stop machine comes with multiple functions to assist the operator in creating maximum cleaning ability. As mentioned above, the minute, compact design generates accessibility to narrow areas or locations of which there is not a lot of room to manoeuvre. Another great feature is transporting of the machine, weighing a measly 22kg, the 7/122 TS does not apply strain to an operator when required to transport around site. To further support this feature, Kranzle integrated a large practical carrying handle.

Quality is at the heart of Kranzle machines, with their heavy-duty (1,400RPM) 4-pole motor attached, which offers quiet – almost silent – operating sound levels. Still also providing maximum life expectancy for the industrial motor. To promote the long-lasting life expectancy, the Total Stop (TS) version works parallel to this feature by automatically switching itself off after periods of non-usage. This protects the motor and pump because the additional pressure switch prevents the motor from running when you release the trigger gun, reducing seal wear if the machine is used intermittently yet left switched on for long periods.

By now I would expect you to believe us when we say this machine is far from domestic use. Still don’t? The indicated machine offers a pressure regulation switch, which is fully adjustable controls that allow operating pressures to be adapted to suit any cleaning task. I bet your domestic machine can’t do that! Another convincing feature regarding Kranzle 7/122 is having the capability to engulf water in from a water tank, even from a height of 1.5meters, so it is not always necessary to directly input to a water supply.

Kranzle 7/122 model also has the convenience element of optional quick-release couplings for lances and foam sprayer, to minimalise time between changing – Essentially speeding up working man-hours on projects.

Why does my Pressure Washer keep blowing fuses?


When it comes to blowing fuses in your pressure washer machine, there are multiple factors which may be at play. Continue reading for the most common mistakes and how to easily avoid, prevent or fix issues regarding fuses.


First thing Aqua Blast Systems tend to ask our customers: Are you using an Extension Lead? As this is usually, from our experience, the main cause for fuses blowing due to Pressure Washers in the UK operating just shy of 13Amps – So with more extension comes more resistance, meaning your fuse is having to work extra hard. Solution: Connect your pressure washer directly into a plug socket for maximum current; or ensure the extension lead cable you’re using is as thick, if not more than the pressure washer cable to enable current to flow easier.

If you decide to use an extension lead, we would highly recommend that you uncoil the entire cable to avoid resistance, over-heating and Voltage drop. It is important that you do so because if your machine does experience a Voltage-drop, naturally, your motor will begin to draw more Amps in an attempt to compensate – Therefore, blowing fuses in your machine or tripping the overload. Another demanding recommendation we insist on is advising that you use a water-proof extension power socket that is RCD fitted.

Overall, if your cable is too short, ALWAYS look to extend your high-pressure hose rather than mains cable.


Recently, has your pressure washer been subject to a high-pressure nozzle replacement? Did you check what size high-pressure nozzle your machine requires? This is another common mistake few of our customers do and the reason it becomes a problem for your fuses is that the wrong size nozzle can potentially restrict the outlet water flow. Imagine your machine requires you to spray water out of a ’10 pence piece’ size hole, and now you have a ‘penny’ size hole. Restricting water flow like this can overload the motor due to a build-up of pressure, as well as possible blowing of fuses. Always check that you are using the correct nozzle size required for your machine to avoid any future controversy.


Machine has been working perfectly for years and now suddenly feels like no power? Your machine is likely to be ‘scaled-up‘ which is the biggest problem, being water orientated, for pressure washers – as you can imagine. Similarly to nozzle sizes, a build-up of limescale can restrict water flow by forcing the hose circumference narrower, which again, can overload the pump and pop fuses.

However, limescale is not only an issue for your hoses, but it also builds up in the boiler and couplings around the machine – You can check if your machine has been a victim to limescale very easily; simply, remove the hose from machine and look down the end to see for any build-up.

Another way, if your machine has high-pressure chemical abilities, you can check for scale by running pressure washer with no hose attached, meaning that your pressure gauge should measure ‘0’. If no hose is attached and the gauge reads more than ‘0’ this is a typical sign for limescale. Solution: Aqua Blast Systems ALWAYS recommend Karcher branded ‘RM110’ for medium and hard water, as it prevents limescale deposits and ensures constant water flow without loss of performance. You can purchase this in-store.


Lastly, fuses dying could just be a machine-related problem. This can consist of many possibilities – We have condensed the top 3 most common problems we encounter regularly: Bypass Valve not operating correctly or Pressure Settings are set too high for the machine. If this is the case for you, what you’ll find happens is fuses blow when releasing the trigger. Solution: We advise taking your Pressure Washer to (ourselves!) an engineer to have your machine looked at professionally.

Are your fuses blowing by only starting-up your machine? This is most likely too much pressure trapped. Solution: Very easy, simplistic fix to this issue: Before powering pressure washer up, squeeze the trigger and release all pressure within hose as this will relieve the motors start-up of high pressure.

Completing the practice of all the above should minimalize the risk of fuses blowing. Thank you.





How to keep your Pressure Washer safe?


Where have I put my wallet? Where’s my phone? Where has my pressure washer gone!?  We understand that sometimes you misplace valuable possessions, as do we, but it’s not always a misplaced mistake… As few of our customers have witnessed first hand, Pressure Washers are amongst the most common cleaning equipment thefts, Aqua Blast has made this guide to potentially safeguard your machine against criminal activity. So here are a few pointers which we suggest to our valued customers as safety precautions to minimalize the risk of theft.


You’re looking to purchase your new pressure washer, now if you’re going to a direct supplier, there is probably nothing to worry about – however, still worth checking, that the machine’s serial number is whole and not ‘tampered’ with. Aqua Blast Systems have been approached before to buy machines without serial numbers for a cheaper price, we refused, but that doesn’t necessarily mean other suppliers will. If you are purchasing a second-hand machine from an individual and you find it has not got a serial number, I highly suggest not pursuing with your purchase as it is most likely a stolen machine and may potentially ‘back-fire’ on you in the future.


You have just purchased your new machine (hopefully from Aqua Blast!), great! The first thing we recommend is taking note of your machine’s serial number, make and model then safely logging it either, online or in a password notebook – Preferably online, as you should always have a back-log this way. This is very important, because if your machine does ‘go missing’ you can report it to companies like ourselves, so if the ‘missing’ machine ever enters our workshop for repair, our excellent database will run through serial numbers to determine if a machine is stolen or not – If a red flag appears, police action is then taken.

Another highly advisable precaution you should take is applying SmartWater to your machine along with a warning sticker. SmartWater is a traceable liquid and forensic asset marking tool that is applied to items of value to deter theft or identify thieves. The liquid discards a long-lasting and unique identifier, whose presence is invisible except under an ultraviolet black light – However, what makes this substance so incredible, is because it’s full of millions of tiny particles; a unique number called “SIN” (SmartWater Identification Number), registered in a national police database together with the owners details, is encoded into each particle/fragment. Speaks for itself, if your machine goes missing, SmartWater can help the recovery process. And if your machine is found, it can confirm directly the owner of the machine.


With the above precautions in place, you should be relatively safe along with common sense – like ensuring that you store your machine in a secure location with a padlock. Nevertheless, Aqua Blast continue to give you these few final pointers which some people don’t take into consideration, for example: Beware leaving your machine unattended while going on a smoke break or lunch break – We have heard cases where machines have been stolen within the hour of the operators break, be sure to always secure your machine because leaving it on ‘display’ will most-likely bring unwanted attraction.

Try to be aware of leaving ‘tell-tale’ signs outside the location of operation, such as Hoses, brushes, lances, triggers etc. It’s no doubt that criminals look out for these particular attachments to target their next victim, leading to an investigation on your property. Which no one wants.

I hope this small article has helped you and given some ideas on how to potentially prevent theft of your machine. Stay safe.
