Code F1
low severity
Miele models: Miele ovens hide the bake element beneath a removable oven floor — lift the floor out for cleaning. The RTD temperature probe is at the rear cavity wall. The MasterChef automatic programmes use a separate wired meat probe (sold as an accessory) — do not confuse this probe connector with the RTD fault sensor.
Common causes
- A touchpad key is stuck or shorted
- Membrane touchpad has deteriorated
- Control board detecting phantom key presses
Step-by-step fix
- Power cycle (flip the breaker for 5 minutes).
- If F1 returns at power-on, a key is stuck — press each key and feel for one that doesn't spring back clearly.
- If the touchpad is a ribbon-connected membrane, inspect the ribbon connector for moisture ingression.
- Replace the touchpad if a stuck key is confirmed.
Tools you may need
Screwdriver set
Prevention
- Clean the touchpad with a dry cloth — moisture intrusion is the primary cause of membrane failure.
- Do not use abrasive cleaners on the control panel.
When to stop DIY
Replace the control board if the touchpad has been replaced and F1 persists.
