Questions and Answers

    What to do if my Wen Pressure Washer doesn’t turn on?
    • R
      Roy FisherJul 28, 2025
      First, make sure the pressure washer is properly plugged into a working electrical outlet. If it is, try a different outlet to rule out a defective socket. Check the fuse and replace it if necessary. Finally, if you're using an extension cord, try using the pressure washer without it to see if the cord is defective.

    Why does my Wen Pressure Washer stop during operation?

      Mr. Dwayne GreenAug 3, 2025
      Your Wen Pressure Washer might stop during operation because you blew a fuse. Replace the fuse, and before doing so, turn off other products sharing the circuit. Alternatively, the nozzle could be partially blocked, so try cleaning it.

    Why is my Wen Pressure Washer pulsating?
    • E
      Elizabeth NguyenAug 8, 2025
      The pulsation in your Wen Pressure Washer could be due to several reasons: * Air may have collected in the inlet hose. To resolve this, allow the machine to run while holding the trigger until adequate pressure returns. * There might be insufficient water supply. Ensure the water tap is open as far as possible. * The nozzle could be blocked. Clean the nozzle. * The water filter might be blocked. Clean the water inlet adapter filter. * The hose could be kinked. Unkink the hose.

    What to do if my Wen PW20 Pressure Washer has fluctuating pressure?
    • T
      Tyler DavilaAug 14, 2025
      Fluctuating pressure in your Wen Pressure Washer can be caused by a few things. The pump might be bringing in air, so tighten the hose connections to ensure they are airtight. Also, the valves could be dirty or broken, requiring cleaning or replacement. Lastly, worn-out pump seals can cause this issue; you can order replacement seals by calling 1-800-232-1195.

    What to do if my Wen PW20 Pressure Washer starts without any water?
    • A
      Ashley HobbsAug 21, 2025
      If your Wen Pressure Washer starts without any water, first, connect the water supply. If that's not the issue, check for a frozen pump or hose and thaw them out. Also, the water filter might be blocked, so clean out the water inlet adapter filter. Finally, the nozzle could be blocked, so unblock and clean it.
