How to Fix / Troubleshooting
Safety first: Unplug the washer before removing the control panel or top cover.
- Inspect control panel: Check for signs of moisture, detergent residue, or physical damage around the buttons and display.
- Check ribbon cable: Remove the control panel fascia to access the ribbon cable or harness connecting to the main PCB. Unplug and replug to clean contacts, ensuring it is fully seated.
- Dry panel: If moisture is present, gently dry the area with a lint-free cloth and allow the panel to air dry completely before reassembly.
- Visual PCB check: Inspect both UI and main PCB for burnt components or corrosion. If damage is visible, replacement of the affected board is recommended.
- Test operation: Reassemble and restore power. If E14 persists, a new UI board or main control PCB may be required; this is typically a technician-level repair.
