Symptoms of a Pressure Washer Pump Not Working

Troubleshooting a Pressure Washer Pump Not Working
If your Karcher pressure washer pump is not working, the first thing you should do is check the power cord to make sure that it is plugged in properly and that the outlet is working. You should also check the breaker box to make sure that the circuit breaker for the pressure washer is not tripped.
If the power cord is plugged in properly and the outlet is working, and the breaker is not tripped, then you will need to troubleshoot the pump itself. Here are a few things you can check:
Check the oil level:
The pump should have a sight glass or dipstick that allows you to check the oil level. If the oil level is low, add oil to the pump until it reaches the full mark on the sight glass or dipstick.
Check the air filter:
The air filter is located on the intake side of the pump. If the air filter is dirty, it can restrict airflow to the pump, which can cause the pump to overheat and fail. Clean the air filter with a clean cloth or replace it with a new one.
Check the water filter:
The water filter is located on the outlet side of the pump. If the water filter is dirty, it can restrict water flow to the pump, which can also cause the pump to overheat and fail. Clean the water filter with a clean cloth or replace it with a new one.
Check the pump impeller:
The pump impeller is a rotating disk that moves water through the pump. If the impeller is damaged, it can cause the pump to lose pressure or not work at all. You can check the impeller for damage by removing the pump housing and visually inspecting the impeller. If the impeller is damaged, you will need to replace it.
