What to do if my DeVilbiss Ex-Cell XR2750 will not draw chemicals?

  Lynn HallAug 7, 2025
  If your DeVilbiss Pressure Washer isn't drawing chemicals, there are a few things to check. First, ensure the spray wand is set to low pressure. Next, inspect the chemical filter for clogs and clean it if necessary. Make sure the chemical hose is fully submerged in the cleaning solution. If the chemical is too thick, dilute it to the consistency of water. Also, avoid using an excessively long high-pressure hose; instead, lengthen the water supply hose. If chemical build-up is suspected in the chemical injector, it is recommended to have it cleaned or replaced by an Authorized Warranty Service Center.

  If the pump of your DeVilbiss Pressure Washer pulsates, it could be due to several reasons. First, verify that the pump oil level is correct. If the incorrect oil was used, drain it and refill with the correct type and amount. Also, check if the vent plug is clogged; clean it by blowing air through it to remove any blockage. Check if the nozzle is obstructed. See Nozzle Cleaning paragraph in the Maintenance section for the correct procedure.

Make sure the spark plug wire is securely attached and the engine ON/OFF switch is in the ON position. If pressure builds up after a couple of pulls, squeeze the gun trigger to release it. Also, verify the water supply is adequate (at least 5 GPM @ 20 PSI), look for leaks at the high-pressure hose fitting and repair if needed, and ensure the high-pressure hose is under 100 feet.
