Unloader Valve Kit
The unloader valve is responsible for holding pressure in the manifold when the trigger is released. If the internal seals on this valve fail or the piston sticks, pressure leaks back to the low-pressure side, causing the pressure switch to cycle the motor on and off repeatedly to maintain standby pressure.

Pressure Washer O-Ring Kit
Electric pressure washers cycle at idle if there is any loss of pressure in the system. Even a tiny, nearly invisible leak at the high-pressure hose connection, the gun-to-wand connection, or the nozzle will cause the motor to surge to replenish the lost PSI.

Pump Manifold Assembly
If replacing the unloader valve does not stop the surging, the internal valve seats or the check valves within the manifold itself are likely pitted or cracked due to mineral buildup or frost damage. Replacing the entire manifold assembly ensures all internal bypass paths are sealed.
