How to Fix / Troubleshooting
Warning: This is an internal high‑voltage fault. Do not attempt to remove or repair the coil without proper training.
- Basic checks:
- Remove all cookware and clean the glass surface.
- Turn off power at the breaker for 10 minutes, then restore and test.
- Zone isolation: Test each zone individually. If E022 appears only on one zone, that coil or its circuit is defective.
- Do not continue using a faulty zone: Continued use may cause further damage to the power electronics.
- Professional repair: A Neff technician should test the induction coil, wiring, and power module, and replace the defective components.
