Possible Causes

Weak internal power supply on module, Failing capacitors, Loose mains connection, Defective power module

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker. Wait several minutes before opening the appliance.

Steps:

  • Check mains connections: Inspect the terminal block for tight, clean connections. Tighten any loose screws.
  • Visual inspection of module: Remove the bottom cover and inspect the power module for bulging capacitors or burnt components.
  • Measure supply (advanced): A trained person can measure the DC low-voltage outputs from the module to the control board to confirm instability.
  • Replace module: If E8 persists and visual signs of failure are present, replace the power module.

Warning: Do not attempt component-level repair unless you are qualified in electronics. Use OEM replacement modules.
