pressure washer model 691583
Hello, I’m having trouble with a pressure washer model 691583, serial: 0906004657. It pressurizes for about one second, then off for about 3 seconds, continuously. It’s not useable in this condition. I have it torn down on my workbench searching for a problem. The pressure overload switch is defective, having shorted to enable continuous contact without interruption. It is not functional, but that alone does not account for the short pulse output performance. With the switch shorted the washer’s output is still one of intermittent pulsation as described above. The motor and all the valves appear to have free movement. The same symptoms prevail regardless of input supply pressure; 30-50psi, or 40-60-psi. Do you have any suggestions as to how I might remedy this problem? Thank you for your attention to this matter. Sincerely, Dave
