Q:

I have a 2550 MAX PSI, gas pressure washer. It is brand new. It ran 45 minutes then quit. It won't restart, it backfires. Do you have any ideas?

A:

Is the oil level correct in the engine?

Hold the gun open and try to start the engine. I suspect the oil wasn't put into the engine or leaked out while it was running. I think you need a technician to diagnose the power washer.

Q:

Why does my 2550 Pressure washer take 20 min to restart after only running for 15 min? It is full of fuel.

A:

The symptom sounds like a bad fuel cap. If the fuel cap vents too slowly, the air inside the gas tank is not replenished as fast as the engine burns it and the tank vapor locks so the engine gets no fuel. It sometimes take 25-20 minutes for the air to fill the tank and the engine will run again.

There could be some unusual issue with the spark ignition module on the engine causing this, but the fuel cap would be my first guess.

You can test this by running the pressure washer without a fuel cap, loosening and tightening the fuel cap every 5-10 minutes, or when the engine dies, loosen the fuel cap and try starting the engine. This will let you know if the fuel cap is the problem.
