Applies to: DEWALT 4 Gallon Lithium-ion Powered Backpack Sprayer (Model DXSP190681)
What causes this: Low liquid level, pump ran dry before refilling, chemical residue in the tank or pump, or a missing/damaged in-tank filter letting debris into the pump.
How to fix it:
- Add liquid to the tank. See Filling the Sprayer.
- Turn the sprayer off and squeeze the shut-off lever until all pressure is relieved.
- Clean the sprayer. See Cleaning. If needed, repeat with warm water and mild detergent, let the mixture sit in the pump for up to 1 hour, then rinse. Replace the pump if necessary.
- Inspect the in-tank filter. Reinstall or replace it if missing or damaged to prevent debris from entering the pump.
