Karcher Pressure washer leaking water
When your Karcher pressure washer is leaking water, the pump assembly is the most likely source. A worn or damaged pump assembly can leak through failed pump seals, especially on a machine that is several years old or used frequently. If the pump is relatively new and the pressure washer is used only occasionally, rebuilding the pump or replacing the pump seals may correct the problem. A complete pump replacement is often the better choice when internal wear is extensive. Another possible cause is the thermal release valve. This valve is designed to open and discharge hot water when the pump temperature becomes too high. That can happen when the Karcher pressure washer is left running while you are not spraying water, so a brief discharge may be normal. If you see persistent leaking, inspect the pump, pump seals, pump o-rings, and thermal release valve for damage. Whether your pressure washer is leaking water from the bottom, leaking from the pump, or leaking water from inside, enter your model number to find the exact replacement part for your specific Karcher pressure washer.

03 - Karcher 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.
