Craftsman Pressure washer leaking water

If your Craftsman pressure washer is leaking water, the pump assembly is the most likely source. A worn or damaged pump assembly can leak through its seals, gaskets, or internal components, especially when the machine is more than a few years old or used often. Replace the pump assembly when it is heavily worn; if it is relatively new and used occasionally, rebuilding the pump or replacing the pump seals may correct the pressure washer leaking water problem. A worn pump itself can cause the same symptom and may require rebuilding or replacement. Another possibility is the thermal release valve. This valve may release hot water during normal operation if the pressure washer is left running while you are not spraying. Water trapped in the pump heats up, and the valve opens when the temperature gets too high. Shut the machine off when it is not in use, and inspect the valve if leaking continues. Whether your Craftsman pressure washer is leaking from the pump or bottom of the unit, enter the model number to find the exact replacement part for your specific pressure washer.

03 - Craftsman Pressure Washer Thermal Release Valve

The leak could be due to the normal operation of the thermal release valve. The thermal release valve allows hot water to exit the pressure washer if the water temperature becomes excessively high. If the pressure washer is left running while it is not spraying water, the water in the pump will begin to heat up. When the water temperature rises above the acceptable limit, the thermal release valve opens to allow the hot water to exit the pressure washer.
