The trigger on the wand feels loose or does not spring back, leading to poor control of solution flow.

Safety: Unplug before dismantling the wand.

• Open wand handle:
  • Remove screws holding the wand handle halves together.
  • Separate carefully to expose the trigger mechanism.
• Inspect trigger components:
  • Check the spring, pivot, and linkage rod.
  • Replace the wand trigger kit (trigger, spring, pins) if worn or broken.
• Check handle for cracks:
  • If the plastic handle is cracked around the pivot, replace the wand handle assembly.
