Leakage from Piston Seals in Undamaged Pump If your Karcher pressure washer leaks water from the bottom, it might be because of damage in the thermal release valve due to overheating. This valve maintains water temperature by recirculating water and releasing excessively hot water. If you notice water leaking at the inlet connection, there’s a fault with the coupling or the seal. After prolonged use of the pressure washer, the coupling and the inlet seal start to wear out and even break. How to Fix – Slide and pull out the inlet cover with the inlet seals to find the red inlet valve in the slot. You can remove this inlet valve with the help of tweezers – and place a new valve there before reassembling the cover and the machine.

Leakage from Outlet Hose or Trigger Wand Connection The outlet seal is at the connection between the pump and the high-pressure washer hose that pushes water to the trigger wand. This point of attachment is similar to that of the inlet connection in structure, complete with couplings and outlet seals. When the pressure washer runs and allows the water in without spraying water, the water heats up. But if the water becomes extremely hot, the thermal release valve can get damaged, causing leakage and pressure loss. How to Fix – You’ll need to pull the pump up slightly, which will allow you to pull out the outlet connector for its replacement – or change the O ring.
