Pressure washer pumps can be burned out in many ways. It's more common than you might imagine.
Whether you left the pump running with no pressure relief, it cracked in storage during the off-season, or perhaps it's just suffered from wear and tear, pressure wash pumps burn out and break from time to time.
However, there's no need to throw out your pressure washer and buy a new one. Instead, just replace your pressure washer pump.
