Possible Causes
Failed auxiliary element (e.g., lower element in some models), wiring fault to auxiliary element, faulty relay on PCB
How to Fix / Troubleshooting
Safety first: Isolate the oven from mains before accessing internal elements.
- Identify affected function: Note which specific mode triggers E023 (e.g., bottom heat, intensive bake). This points to the associated element.
- Visual inspection: Inspect the relevant element (often hidden under the cavity floor or behind panels) for cracks or burn marks.
- Continuity test: Disconnect the element and measure resistance. Infinite resistance indicates a failed element.
- Check wiring: Inspect connectors and wiring from the element to the control board.
Replace the faulty auxiliary element. If the element is good but not powered, the corresponding relay or PCB track may be defective.
