Possible Causes
Unstable or low mains voltage, Incompatible inverter or generator supply, Faulty mains sensing circuit on PCB, Loose mains connections
How to Fix / Troubleshooting
Safety first: Always disconnect the dryer before inspecting electrical connections.
- Check supply quality: Ensure the dryer is connected directly to a standard wall outlet, not via a long extension or low-quality inverter.
- Test voltage: Use a multimeter (if competent) to verify that the mains voltage is within the range specified on the rating plate.
- Inspect terminal block: Check the internal mains terminal block for loose screws or heat damage. Tighten and repair as needed.
- Try a different outlet: Plug the dryer into another known-good circuit to rule out house wiring issues.
- If E18 continues with good supply: The mains sensing circuitry on the PCB may be defective and require board replacement.
