How to Fix / Troubleshooting
Safety first: Remove the battery before attempting to free a stuck button. Do not use excessive force.
- Step 1 – Inspect button movement: Press the power button several times with the battery removed. It should move freely and click. If it is stuck, gently work it around the edges.
- Step 2 – Clean around button: Use a slightly damp cloth to clean around the button area. For dust, use a soft brush. Do not allow liquid to enter the housing.
- Step 3 – Drying (if spill occurred): If liquid was spilled on the handle, remove the battery and allow the unit to dry for at least 48 hours in a warm, ventilated area.
- Step 4 – Test function: Reinstall the battery and test. If the button still fails intermittently, the internal switch or PCB is likely damaged.
- Step 5 – Replace handle/PCB: Power switches are typically integrated into the handle PCB and require professional replacement.
