Possible Causes
Failed low-voltage power supply on main PCB, Short circuit on control electronics, Damaged transformer or SMPS components, Overloaded accessory circuit
How to Fix / Troubleshooting
Safety: Disconnect power and wait for capacitors to discharge before touching the PCB.
- 1. Visual inspection: Remove the cover and inspect the main PCB for burned components, bulging electrolytic capacitors, or cracked solder joints.
- 2. Check for shorts: Disconnect any optional accessories (e.g., external control modules) and see if E14 clears.
- 3. Board replacement: Internal power supply faults are not typically field-repairable. Replace the main control board with a genuine Kospel part.
- 4. Verify supply: After replacement, confirm that mains voltage and wiring are correct to avoid repeat failures.
