Possible Causes

Loose ribbon cable between display PCB and main PCB, Oxidized or damaged control panel connector, Faulty display/control PCB, Main control board communication failure

How to Fix / Troubleshooting

Safety first: Disconnect the appliance from mains power before opening the control panel or accessing the main PCB.

  • Access control panel: Remove screws or clips securing the front control panel. Gently pull it forward to expose the wiring and ribbon cables.
  • Inspect connectors: Check the ribbon cable and plug connectors for kinks, cracks, or discoloration. Reseat all connectors firmly on both the control panel and main PCB.
  • Clean contacts: If you see light corrosion, use electrical contact cleaner and a soft brush or lint-free cloth to clean the contacts. Allow to dry fully before reconnecting.
  • Check for damage: Look for burn marks or broken tracks on the control PCB. If present, the control panel PCB will likely need replacement.
  • Power up and test: Reassemble the panel, restore power, and check if E5 clears. Test all buttons and temperature adjustments for proper response.

When to call a technician: If reseating and cleaning connectors does not resolve E5, either the display PCB or main control board is likely faulty and should be professionally diagnosed and replaced.
