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.
