The Karcher Washer Is Leaking

    Spray Wand

    • Disconnect the spray wand if the Karcher power washer is leaking and then insert the spray wand firmly into the trigger holder. Push the spray wand in slightly until you can feel tension against the internal spring and then turn the spray wand clockwise until locked into position. If the spray wand is loose, water can leak.

    Wand Inserts

    • If the washer continues to leak, disconnect the spray wand again and look inside. If the plastic insert or the O-ring inside the spray wand is missing, damaged or broken, the wand cannot operate correctly. Contact Karcher for replacement parts.

    Hose Connections

    • Another potential source of leaks is the water hose connection to the Karcher washer. Tighten the hose connection at the water valve as well as on the power washer. If the water is leaking from the hose despite tight fittings, disconnect the hose and look inside. If the water seals are damaged or worn out, the seals will need to be replaced.

    Thermal Protection

    • The power washer is programmed to shut off automatically and reset if the unit overheats. This may cause water to leak due to the sudden shutoff. Wait for the power washer to reset, and make sure the unit is plugged into a grounded, dedicated outlet and nothing is blocking the appliance and obstructing power or air flow. Contact Karcher if the power washer continues to shut off automatically due to overheating, as the motor may need service.
