Fix at homeStuck key
A key on the control panel has read as pressed for longer than the control allows.
- Press each key once and feel for one that does not spring back.
- Wipe the glass or the membrane dry — a spill or a cleaner on the panel holds a touch key down; let it dry fully.
- Breaker off one minute, on again, set the clock.
A key still stuck after cleaning is the touch panel (the user interface) — a part; on many of these it comes together with the control board.
