With temperatures dipping lower and lower it’s time to think about properly storing your power washer for the winter.
By taking a little time out of your day to winterize you’ll be saving your machine from the potential damage of cold temperatures.
Getting rid of residue
The first step to winterizing your power washer is getting rid of any remaining detergent that might have built up in the hoses and pumps of the machine.
You can do this by running hot water through your machine and breaking up any build up. Either pour hot water into your detergent tank or use the detergent hose to siphon hot water from a different source.
Next you’ll want to run your pressure washer for about a minute on low pressure. This will help flush out any remaining residue.
Flushing out the water
When the cold sets in the last thing you want is for any remaining water inside your power washer to freeze. This can potentially damage your pump as the ice expands
First remove the garden hose (after turning it off) from your power washer. Then hold down the trigger of the lance to depressurize it.
Next you’ll want to remove the lance and hose from your power washer to be able to get the rest of the water still in the machine to come out.
With your power washer still plugged in, turn it on and gently rock it back and forth for 5 to 10 seconds. If there is any remaining water it should come out during this process.
Even though you’ve gone through the steps to winterize your power washer there is always a chance that freezing temperatures can freeze/crystallize the moisture inside.
Best practice is to store your power washer in an area that doesn’t get below 40 degrees. That means no detached garages, sheds, etc.
Take care of any last minute chores before it’s time to put away your power washer for the winter.
