How to Troubleshoot a Burner Not Working

If the fuel pump starts to run, the fuel pump is good. If the fuel pump does not start to run, the fuel pump is faulty.
4. Check the control board. If the control board is faulty, it will not be able to send the signal to the fuel pump to start. To check the control board, turn on the pressure washer and look for any error codes. If you see an error code, the control board may be faulty.
