Possible Causes

How to Fix / Troubleshooting

Safety first: Remove the battery pack before working near the trigger or control buttons.

Steps to address mode selection issues:

  • 1. Inspect buttons and trigger: Check that the power trigger and mode buttons move freely and return when released. Look for dirt or sticky residue around the buttons.
  • 2. Clean around controls: Use a dry, soft brush or compressed air (low pressure) to remove dust from around the trigger and buttons. Do not spray liquids or solvents into the controls.
  • 3. Test operation: Refit the battery and test each mode button. If the LEDs flash and revert or do not respond, the switch or interface board may be faulty.

Next steps: Replacement of the trigger switch assembly or user interface PCB is typically required if cleaning does not restore function. This involves disassembling the handle and should be done by a technician familiar with Hoover Candy cordless models.
