Most Common Reasons Craftsman Pressure Washer Pump Not Working

Clogged Inlet Filter

The inlet filter is located on the inlet hose, near the pump. It prevents dirt and debris from entering the pump and damaging it. If the filter is clogged, it will restrict the flow of water to the pump, causing it to overheat and eventually fail.

Clogged Outlet Filter

The outlet filter is located on the outlet hose, near the gun. It prevents dirt and debris from being sprayed out of the gun. If the filter is clogged, it will restrict the flow of water out of the gun, causing it to lose pressure.

Low Oil Level

The pump requires oil to lubricate the moving parts and cool the engine. If the oil level is too low, the pump will overheat and eventually fail.

Dirty Oil

The oil in the pump can become contaminated with dirt and debris, which can damage the pump. It is important to change the oil regularly to prevent this from happening.

Bad Gasket

The gaskets in the pump can wear out over time and allow water to leak into the engine, causing it to overheat and fail.

Bad O-Ring

The O-rings in the pump can also wear out over time and allow water to leak into the engine, causing it to overheat and fail.

Bad Pressure Switch

The pressure switch controls the flow of water to the pump. If the pressure switch is faulty, it will not allow the pump to build up pressure, causing it to overheat and fail.
