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.

WHAT IS KARCHER RM111 ASF?

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).

WHY SHOULD I USE KARCHER RM111 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. However, it has other incredible benefits such as protection against Black Water released from the lance, prevents corrosion against heating coil and overall, cares for the machines pump. Therefore, reducing maintenance costs and prolongs the lifetime of the heating coil.

FIELDS OF APPLICATION:

Hot Water High-Pressure Cleaners with Machine Protector Adaptation with Application Temperatures between 60° and 150°C

DOSAGE: 6ml/°dH and m³

Components in Accordance with 648/2004/EC

HOW TO APPLY KARCHER RM111 ASF:

Important Notice: If you apply the dosage yourself, Follow dosage recommendations to avoid any issues. Otherwise, a servicing engineer can set-up the dosage according to your water-hardness.

Remove the screw lid, then insert the bottle into device upside down (head-first) and pierce first-use foil by pushing the bottle down against machine.

MAIN BENEFITS OF KARCHER RM111:

  • Approved protection against calcification for usage in high-pressure cleaners
  • Special components protect against corrosion in the heating coil and all-water bearing parts

Why does my Pressure Washer keep blowing fuses?

WHY IS MY MACHINE 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.

ONE – EXTENSIONS:

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.

TWO – NOZZLES:

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.

THREE – LIMESCALE:

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.

FOUR – MACHINE:

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 Maintain your Pressure Washer during Winter?

WINTER MAINTENANCE FOR

YOUR PRESSURE WASHER

Great Britain winter season is almost upon us, and for many pressure washer users, this season hits where it hurts most… In the machine.

Now its no secret that pressure washers can cost a small fortune, so taking the correct procedures for maintenance is always the best interest, especially when frozen damage is not covered on the warranty! Aqua Blast get queries each year regarding this topic. What is the correct way to store your machine without damaging any components? During winter months, frosty conditions can freeze and destroy pump, pistons, seals and more – which can cost a fair few quid for repairs. So buckle up, read this brief, simple guide to a healthy machine this winter.

FIRST THINGS FIRST.

We recommend that you start by disconnecting all hoses from the machine (Inlet, outlet, chemical etc) and then proceeding to run the machine for a short period of time. While they’re no hoses connected, the excess water will drain out on the floor.

For your best attempt at a functioning pressure washer at winters end, we suggest that you leave the hoses disconnected to allow for any remaining water in them to expand – Pulling the trigger will release any left-over pressure in the hose and force disposal of the water within. Try to ensure that majority of the water is drained to prevent any slim chance of water travelling through the hose, freezing and cracking components.

Finally, confirm your machine is fully switched off, not left in standby mode, then store inside a frost-free container or unit. Storing machines with combustible properties, such as diesel or petrol, in your home, is not the best idea, for obvious reasons. So be sure to empty the tank and keep away from any potential igniters. Safety First!

“MY MACHINE HAS ALREADY FROZEN, WHAT DO I DO?”

Definitely do not make the mistake of starting the machine. This will destroy components such as the pump because small ice blocks form inside the unit and can cause damage to the pistons within the pump – This will more than likely result in a new pump requirement.

Do not leave water inside your machine because this will cause it to freeze and most likely crack components on the machine, causing leaks or pressure drop on the pump.

Do not leave water inside your high-pressure hose, as it can freeze and make the circumference of the hose smaller, meaning the desired water flow is not travelling through which can cause the unit to stop spraying or cause the machine to pulse – eventually overloading the pump.

“WHY IS MY STATIC MACHINE FROZEN, WHEN IT HAS A FROST HEATER?”

Static machines require a constant flow of power to the unit, in order to run the frost heater. As it says on the tin, ‘frost heater’ is designed to stop your machine from freezing up. However, if you still found your machine frozen it is a very simple answer: Either you require an engineer to check for faults – or as mentioned above, a constant flow of power, are you switching your machine off at the wall socket? If you are this will cut all power to the unit, so ensure you only switch the unit off on the control panel and your ‘frost heater’ will continue doing its job!

FINALLY SOME SAFETY POINTS:

  •  DO NOT go ahead after a long period of time usage and cover the exhaust ready for winter – Goes without saying, this is a fire hazard.
  • Vice versa, do not start your hot water machine with a cover over the exhaust as this can also cause a fire.
