How to Fix / Troubleshooting
Safety first: Unplug the unit if beeping is continuous and cannot be silenced.
- Step 1 – Clean and dry panel: Wipe the control panel with a dry, soft cloth. Ensure no moisture or cleaner residue remains.
- Step 2 – Power reset: Unplug for 10–15 minutes, then plug back in and observe.
- Step 3 – Inspect keypad (advanced): Remove the front bezel to access the control interface board. Check for signs of liquid ingress or corrosion.
- Step 4 – Replace interface board: If corrosion or stuck button contacts are found, replace the control interface board / keypad assembly.
- Step 5 – Board noise: If the keypad is clean but beeping persists, the main control PCB may be misreading inputs and should be replaced.
