How to Repair a Generic Pressure Washer

Verify the pressure washer has fuel and that the gas is the right type for your specific model. Putting diesel fuel in an unleaded tank or vice versa causes engine damage, and the pressure washer won't work properly if you use the wrong fuel type. An electric power washer needs to be plugged in or have a full battery.

Ensure the pressure washer is getting water and that the water valve is open if the engine is running but water flow is a problem. Check the hose on the pressure washer to make sure it isn't kinked. A kink prevents water from flowing properly through the system.

Look at the hose and nozzle to check for leaks. If the washer is leaking, you won't get good water pressure from the machine. Replacing a leaking hose or temporarily sealing it with tape restores proper pressure to the pressure washer.

Place a higher pressure nozzle on the end of the sprayer to increase water pressure. You may be using a low pressure tip that negatively affects your cleaning pressure.

Change the filters on the sprayer if the detergent isn't mixing with the water spray. Follow the instructions for your specific sprayer, as the method for changing the filters varies by model.

Turn up the throttle on the engine if it is sluggish or running slow. It often helps to move the choke into the halfway position until the engine starts running smoothly.

Request professional service if the pressure washer still isn't working properly.
