Possible Causes
Mains voltage out of range, Faulty internal power supply on PCB, Loose mains connection block, Damaged surge components on control board
How to Fix / Troubleshooting
Safety first: Unplug the dryer before opening any covers. Work on live mains circuits only if you are qualified.
Steps to check and fix:
- Check mains supply: Verify that the outlet voltage is within the specified range for your Balay dryer (typically 220–240 V AC in EU). Avoid using extension leads or multi-plug adapters.
- Inspect mains cable and terminal block: Remove the rear cover to access the mains terminal block. Tighten any loose screws and look for signs of overheating or burning. Replace damaged parts.
- Power reset: Leave the dryer unplugged for 10–15 minutes, then reconnect and test.
- Control board inspection: If comfortable and qualified, inspect the PCB for burnt tracks, bulging capacitors, or damaged varistors. Replace the main control module if the internal power supply is faulty.
- Professional service: Persistent E15 usually requires board-level diagnostics and should be handled by a Balay service technician.
