1. Control unit faulty.
1. Niche temperature too high (caused by second appliance?).
2. Cool air fan failure.
3. Power failure during baking process.
1. Short circuit in water temperature sensor or in its wiring.
2. Boiler leaking water.
1. Break or loose contact in water temperature sensor or in its
wiring.
1. Break in flange (fastening screws not tightened enough, etc.).
2. Heating element for boiler is faulty. Over-temperature protection
activated (caution: one of which is self-resetting).
3. Food probe socket dirty / wet.
4. Boiler very scaled up. Descale.
1. Button is mechanically blocked or jammed.
2. Moisture on the control unit.
1. Moisture on the control unit.
1. Quit error in the case of appliances with K3.20398-0 or
K3.20398-1 software. Message probably caused by software
error.
2. Wrong connection of neutral and pole conductor in case of
1–phase connection (Applies for appliances with processor with
version smaller -2).
3. Processor faulty.
1 Water tank valve not tight.
1. Pole conductor connected to neutral conductor terminal.
2. Neutral conductor break in the house wiring system.
3. Mains calibration error (see error code E63).
