Handle trigger error, unit does not spray or start brush when trigger is pressed

Safety: Unplug the carpet cleaner before opening the handle assembly.

• Check mechanical movement: Squeeze the trigger and feel for normal resistance and return. If it feels loose or does not spring back, the trigger lever or spring may be broken and require replacement.
• Inspect the trigger switch: Open the handle housing and locate the microswitch or sensor activated by the trigger. Verify that the trigger physically actuates the switch.
• Test the switch: Use a multimeter in continuity mode across the switch terminals. It should change from open to closed when the trigger is pressed. Replace the switch if it does not operate correctly.
• Check wiring: Ensure the harness from the handle to the main body is intact and firmly connected at both ends. Look for pinched or broken wires.

After replacing a faulty trigger switch or lever, reassemble the handle carefully to avoid pinching wires.
