Possible Causes
Corrupted settings in EEPROM, Failed memory IC on main PCB, Voltage spike damage to control electronics
How to Fix / Troubleshooting
Safety: Disconnect from mains before any inspection.
- Power cycle: Unplug the unit for at least 10–15 minutes to allow capacitors to discharge and memory to reset. Plug back in and test.
- Factory reset: If the Philips model supports it, perform a factory reset via the control panel (refer to user manual for key combination).
- Surge protection: If E7 appeared after a storm or outage, use a surge-protected outlet going forward.
If E7 persists, the main control PCB (with EEPROM) is likely defective and must be replaced as an assembly. This involves mains wiring and should be done by a qualified technician.
