When your WorkForce pressure washer is leaking water, the pump assembly is the most likely source. A worn pump, damaged pump seals, or failed pump o-rings can allow water to escape from the pump or bottom of the machine, especially on an older washer used frequently. If the pump is relatively new and the washer sees light seasonal use, rebuilding the pump with new seals may solve the leak; otherwise, replace the pump assembly. A damaged pump head, manifold, valves, or fittings can also cause the pressure washer pump to leak. The next possibility is the thermal release valve. This valve may release hot water during normal operation if the washer runs without spraying, because water trapped in the pump overheats. Avoid leaving the WorkForce pressure washer running while the trigger is released. Before servicing, shut off the engine or electric motor, disconnect the water supply, and relieve pressure from the spray gun. Whether your pressure washer is leaking from the pump, leaking water from the bottom, or leaking at a connection, enter your model number to find the exact replacement part for your specific WorkForce pressure washer.

You may need to rebuild or replace the pump assembly. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump assembly. If the pump is relatively new, and you don’t use the pressure washer often, either rebuild the pump assembly or replace the pump seals.

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.
