How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and unplug the dryer before inspecting electrical connections.
- Verify supply: Use a multimeter or have a qualified person confirm that the outlet provides the correct voltage and frequency for your Essentials dryer (typically 220–240 V, 50 Hz in many regions).
- Inspect power cord and plug: Check for damage, burns, or loose pins. Replace the power cord if any defects are found.
- Check internal terminal block: Remove the rear cover over the mains terminal block. Ensure all screws are tight and there are no signs of overheating.
- Control board power supply: If supply is correct and connections are sound, the low-voltage power supply on the main control PCB may be faulty and require board replacement.
