For internal use only
F 9 Rise in air temperature faulty (when
the evaporator heater is activated the
air temperature rises too slowly)
1. Oven leaks (loss of steam, exhaust air slider leaks, food sensor
socket defect, doors not closed properly?)
2. Air temperature sensor does not react. Probe dirty/wet
3. Too much cold food has been put into the oven (for steaming a
max. 2 kg of food is permissible)
4. Gasket of the hot-air fan missing or defect. To check: Working
from the oven, remove the hot-air panel and the rotor (caution:
left-hand thread!)
F 10 Button contact faulty
Closed for more than a minute
Humidity sensor (uncovered strip con-
ductor) occupied for more than 20 sec-
onds.
1. For F1a: Operating element moist as a result of steam getting
behind the panel.
2. For F1a: Button on the operating element jammed or moisture
on the operating element.
F 11 Button contact faulty
Closed for more than a minute
Humidity sensor (uncovered strip con-
ductor) occupied for more than 20 sec-
onds.
1. No L2 terminal wire (e.g. fuse/automatic cut-out has tripped)
2. Cooling-air fan defect
3. Fan wheel jammed or the fins are dirty in the area of the sensor
4. Speed sensor displaced or sensor defect
F12 Computer temperature gauge
a) excessively low resistance
b) excessively high resistance
1. ei F2a: Computer temperature gauge on the computer has short
circuited
2. For F2b: Computer temperature gauge on the computer has
been interrupted
F 13 Computer excessive temperature
Computer temperature gauge meas-
ures a temperature in excess of
80°C
1. Niche temperature too high (caused by a second appliance?)
F 14 Excessive oven temperature
Oven temperature gauge measures a
temperature in excess of
260°C
1. Oven temperature sensor (PT500) defect or probe wet/dirty
2. Hot-air fan defect (for oven temperature settings of more than
200°C)
F 15
F 16 Excessive evaporator temperature
Water temperature gauge measures a
temperature in excess of
102°C
1. Evaporator leaks. Probe dirty/wet
2. Not enough water in the evaporator (check the level gauge)
F 17 Excessive air temperature
Air temperature gauge measures a
temperature in excess of
140°C
1. For the 0 SW version: Excessively high temperature for “damp
hot-air” or “hot air with vapours” (caution: this may occur during
standard operation)
2. Hairline crack on the plastic sensor
F 18 Empty during descaling process
faulty
The level pin develops too little resist-
ance when water is being pumped out
(too little difference before and after
pumping out)
1. Foam in the evaporator casing (unsuitable descaling agent)
2. Discharge pump does not transport sufficiently (hose crushed)
3. Intake valve leaks (valve leak, limestone chips in the gasket,
etc.)
F 19 Level faulty after descaling
Level pin develops low resistance at
the end of the descaling process
(after rinsing)
1. Foam in the evaporator casing (unsuitable descaling agent)
2. Intake valve leaks (valve leak, limestone chips in the gasket,
etc.)
F 20 Level pin dirty
The level pin becomes dirty soon after
the appliance has been descaled
1. Unsuitable descaling agent used (insulation layer on the pin?)
2. Water intake blocked or limescaled
3. Supply pump jams, hose crushed
4. Insufficient water conductivity (demineralised water used?)
F 21 Water intake faulty
pumping out several times within two
hours in the standby or baking mode
1. Intake valve leaks (valve leak, limestone chips in the gasket,
etc.)
2. Foam in the evaporator casing (particularly after descaling)
