Symptoms
- Nothing comes out of the wand when the trigger is pulled
- No water flow sound from the machine
- Engine or motor runs but wand is completely dry
- Water dribbles slightly but doesn't spray
Likely causes
- CommonGarden hose not connected or spigot turned offThe most basic and most overlooked cause; always confirm this first.
- CommonFully clogged inlet filter screenA completely blocked screen can stop flow entirely rather than just reducing it.
- CommonNozzle tip completely blockedDebris can fully plug a narrow nozzle opening.
- PossibleKinked garden hose or high-pressure hoseA sharp kink can fully pinch off flow.
- PossibleWand or gun safety lock engagedSome guns have a lock that fully blocks the trigger and flow when engaged.
What to do
- Confirm the garden hose is fully connected at both ends and the spigot is turned all the way on.
- Check the wand's safety lock isn't engaged, preventing the trigger from working.
- Look along both the garden hose and high-pressure hose for kinks pinching off flow.
- Remove and inspect the nozzle tip for a full blockage, clearing it with a cleaning pin.
- Check the inlet filter screen where the garden hose attaches for a complete clog.
- Disconnect the wand from the gun and squeeze the trigger to see if water flows from the gun alone, which helps isolate whether the wand or upstream system is blocked.
- If water still won't flow with everything clear and connected, the pump itself may not be drawing water and needs professional inspection.
