How to Fix / Troubleshooting
Safety first: Unplug the dryer before opening any panels. Do not touch live terminals.
- Check plug and outlet: Ensure the plug fits tightly in the outlet. Try a different outlet if possible.
- Inspect mains filter and wiring: Access the mains filter board and check for loose connections or burnt components. Tighten terminals and replace the filter if damaged.
- Household circuit: Avoid running multiple high-power appliances on the same circuit as the dryer.
- Control board: If flickering persists with good supply, the main PCB may have a failing power supply section and should be replaced by a technician.
