Winter Maintenance of Karcher Pressure Washers

The British winter brings dark mornings and evenings plus heavy frost, but using a Karcher pressure washer can help to keep your yard clean.

Here at Britclean, we offer a host of well-known brands such as Karcher, Ehrle, Nilfisk, Interpump plus our own brand of pressure washers.

In our latest blog, we are going to share some storage tips for your pressure washer, to make sure it can be used all year round.

Winterising your Pressure Washer

We are going to focus on essential areas to keep your pressure washer protected from colder conditions


With freezing temperatures at night during the winter, you can’t just pack your pressure washer away and have it spent weeks or months in a shed. You will need to carry out some maintenance tasks so that when it comes to using it again it is working properly.

Four Essential Steps

Flush – Firstly, fill your detergent tank with warm water and if you have a suction tube place it into a warm bottle of water and turn on the pressure washer. This will remove any residual soap and helps to clean the inside of the equipment.
Disconnect – Start disconnecting parts of the pressure washer, removing the lance and hose and drain any water left inside. For the hose, you may be required to drain any leftover water out then coil it up ready for storage.
Power Up – Now power up the pressure washer again, but without the hose and lance connected. This will help to remove the remaining water in the system. Turning it on and rocking the pressure washer gently will ensure all water is blasted out. Do this for 10-15 seconds then turn it off.
Storage – Once all the parts have been removed and water is drained out, you can unplug and coil all hose and power leads up ready for storage. We would recommend keeping your pressure washer in your house, business premises or garage to prevent winter damage from the cold. Not following these steps, can cause cracks to internal pipes or damage to the seals.

Outside Taps

Once your pressure washer is stored away you will need to look at your outside tap. Remember an outside tap can freeze and could burst or cause pipe damage. This can be prevented by using an outside tap jacket which helps to insulate the tap and prevent the cold and frost from freezing it.
