    Why does the spray pressure vary on my Westinghouse Pressure Washer?
    • T
      Tara LeeAug 17, 2025
      If the spray pressure of your Westinghouse Pressure Washer varies, it could be due to several reasons: * Poor inlet water supply. * The garden hose inlet filter may be clogged: Remove the garden hose and clean the filter. * The spray nozzle may be restricted: Remove particles with a nozzle cleaning tool. * Air may be entering the pump: Check all hoses and fittings for secure connections. With the water supply ON and the engine OFF, purge the pump of air by depressing the trigger until a steady stream of water flows.

      Joseph CollinsAug 21, 2025
      If your Westinghouse Pressure Washer isn't reaching high pressure, consider these possibilities: * The water supply may be restricted: Check hoses for leaks, blockages, or kinks. * The garden hose may be too small: Use a 5/8 in. (0.025 mm) hose or larger. * There may not be enough inlet water: Turn the garden hose water supply fully ON and check hoses for leaks, blockages, or kinks.

    Why is the low pressure detergent wash not working on my Westinghouse WPX3600?
    • C
      Christine HarrisAug 28, 2025
      If the low-pressure detergent wash is not working on your Westinghouse Pressure Washer, consider the following: * The wrong nozzle might be installed on the spray lance: Detergent only works with the black (low pressure) nozzle installed. Install the black nozzle; replace it if missing. * The detergent might be too thick: Use a detergent made specifically for pressure washer use. * The detergent hose might not be connected to the pump: Check hose connections. * The spray nozzle might be obstructed: Clean debris from the nozzle. * The detergent hose could be clogged: Remove the detergent hose and clean or replace it. * There might be a blockage inside the pump detergent valve: Quickly depress and release the spray gun trigger 4-5 times to clear the detergent valve.
