Possible Causes

Broken trigger linkage, Stuck solution valve, Disconnected trigger rod, Cracked handle assembly

How to Fix / Troubleshooting

Safety first: Unplug the unit and empty the tanks before working on the handle.

  • Inspect trigger movement: Squeeze the handle trigger and observe if it returns smoothly. If loose or floppy, the internal linkage may be broken.
  • Open handle housing: Remove screws to split the handle and access the trigger mechanism. Check the trigger rod and spring for damage or disconnection.
  • Check solution valve: At the base, verify that the mechanical valve or microswitch actuated by the trigger moves freely. Clean any dried detergent buildup.
  • Replace damaged parts: If the trigger or linkage is cracked, replace the handle and trigger assembly with a genuine Hoover part.
