How to Fix / Troubleshooting
Safety first: Unplug the appliance before inspecting electrical connections. Only perform basic checks if you are competent; otherwise call a professional.
- Check outlet: Test the wall socket with another appliance to ensure stable power. Avoid using extension leads.
- Inspect mains cable: Check the power cord for cuts, burns, or kinks. If damaged, have it replaced by a qualified technician.
- Internal connections: Remove the rear or top panel to access the mains terminal block and EMI filter. Ensure all screws are tight and there are no signs of overheating.
- Surge issues: If E18 appears after storms or power cuts, consider using a surge protector once the machine is repaired.
- Professional repair: If connections are sound, the internal power supply on the PCB or the EMI filter may be faulty and should be replaced by a technician.
