If your pressure washer is not building pressure (and the engine is surging), there could be a few different causes. One of them is a sticking unloader valve.

Here we show you how to make sure the unloader valve on your home pressure washer is clean in just 2 minutes.

If this does not fix your pressure washer and make it build pressure again, then it is likely a water pump problem. We tackle that next time.
