Symptoms of a Pressure Washer Pump Not Working

There are a few different symptoms that can indicate that your Northstar pressure washer pump is not working properly. These include:

The pressure washer is not producing any water

Troubleshooting a Pressure Washer Pump Not Working

If your Northstar pressure washer pump is not working, there are a few things you can check to try to troubleshoot the problem.

1. Check the water supply:
Make sure that the water supply to the pressure washer is turned on and that there is no blockage in the hose.

2. Check the pressure switch:
The pressure switch is a valve that regulates the flow of water to the pump. If the pressure switch is stuck open, it will prevent the pump from building up pressure. To check the pressure switch, turn off the pressure washer and disconnect the hose from the pump. Then, use a multimeter to check the resistance of the pressure switch. The resistance should be between 50 and 100 ohms. If the resistance is too high or too low, the pressure switch will need to be replaced.

3. Check the pump:
The pump is the heart of the pressure washer. If the pump is not working, it will not be able to produce any water. To check the pump, remove the cover and look for any damage to the impeller or other internal components. If you see any damage, the pump will need to be replaced.

4. Check the hose:
The hose is another common cause of pressure washer problems. If the hose is kinked or damaged, it will restrict the flow of water to the pump. To check the hose, inspect it for any kinks or damage. If you find any damage, the hose will need to be replaced.

5. Check the nozzle:
The nozzle is the part of the pressure washer that directs the water stream. If the nozzle is clogged, it will restrict the flow of water and reduce the pressure. To check the nozzle, remove it from the pressure washer and clean it with a wire brush.

6. Check the regulator:
The regulator controls the pressure of the water stream. If the regulator is set too high, it will damage the pump. To check the regulator, turn off the pressure washer and adjust the pressure setting. The pressure should be between 2,000 and 3,000 psi.

7. Check the electrical connections:
Make sure that all of the electrical connections are secure. If the connections are loose, it can cause problems with the pump.

8. Replace the pump:
If you have checked all of the other possible causes and the pressure washer is still not working, the pump will need to be replaced.
