How do you maintain an electric pressure washer?
Disconnect Components & Pour Out the Soap
Pour out any remaining detergent and place your lance and your gun in their respective storage places on the pressure washer. You can pour left-over soap back into your soap jug to be more conservative, then rinse out your detergent tank to minimize messes.

Do electric pressure washers overheat?
Although electric pressure washers can overheat, it happens much less frequently than it does with gas-powered units.
Do electric pressure washers last long?
When it comes to durability, gas pressure washers trump electric pressure washers. Gas-powered units can last for ten years, easy. Electric pressure washers, on the other hand, tend to only last 3 to 5 years, depending on the maintenance.
Is it OK to run pressure washer without water?
Using pressure washers without water is risky and can damage your machine. The water helps to cool the pump, and without it, the pump can get overheated and breakdown.

Why is my pressure washer revving up and down?
The engine of your pressure washer may rev sporadically because it is experiencing an intermittent blockage of the air that it needs to function properly.

Why does my pressure washer keep starting and stopping? Another possible reason your pressure washer starts and stops after a few minutes is that the fuel cap vent or the fuel filter might be clogged. What is this? The fuel cap allows air into the fuel tank so that it can continue to deliver gas to the carburetor even as the fuel level gets lower.
Why does my electric pressure washer start then shut off?
If the engine of your electric pressure washer gets started and runs fine for a couple of minutes and then loses power, it’s probably the unloader valve that has failed. When the unloader valve of your electric pressure washer fails, it is unable to recirculate the water back to its pump inlet.
