For internal use only
F7 Water temperature does not rise
sufficiently
(the water temperature
does not rise sufficiently when the
evaporator heater is activated)
1. Heater defect, flange interruption (protection against excessive
temperatures)
2. Faulty wiring (plug connections, interruption, short circuit, loose
contact, etc.)
3. Water temperature gauge does not react (plug of the water tem-
perature sensor dirty, etc.).
4. Computer defect (relay, etc.)
F9 Rise in air temperature faulty
(when the evaporator heater is acti-
vated the air temperature rises too
slowly)
1. Exhaust air slide has come out or the steam hole is blocked
2. Oven leaks (loss of steam, doors not properly closed?)
3. Air temperature sensor does not react. Probe dirty/wet
4. Too much cold food has been put into the oven (for steaming a
max. 2 kg of food is permissible)
F 10 Button contact faulty closed for
more than a minute
1. Button that has got caught on the control panel
2. The computer will get damp in the area of the flat cable as a
result of a lead in the red silicon bead
3. The operating element will become damp as a result of steam
getting into the space behind the panel
F 17 Excessive air temperature 1. Hairline crack on the plastic sensor
F 20 Level pin dirty
The level pin becomes dirty soon
after the appliance has been des-
caled
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?)
No
message At times unusual illegible signs on
the text display 1. VFD module is damp as a result of steam getting in behind the
panel
2. VFD module defect or computer possible defect.
No signal Heater for hot air does not heat up. 1. There is no supply on the L2 terminal of the calculator (instruc-
tions for installation observed?)
2. Hot-air heater faulty (plug connections, interruption, short cir-
cuit, loose contact).
3. Manual cut-out with thermostat F1 (or F2 if present): Manual re-
setting required Possible causes
• Heater has an earth fault
• Relay contact welded on the computer
• Hot-air fan defect/blocked
• Thermostat F1 (or F2 when present) switches incorrectly
• Oven temperature gauge measures incorrectly (exces-
sively low readings)
Note: The appliance will need to be replaced if the muffle becomes
brown.
4.
Calculator defect (relay, etc.)
• (the appliance will need to be replaced if the are signs of
overheating on the muffle)
dEno Demonstration mode is activated
(message only appears after a power
cut)
The mode intended for exhibition purposes. No heaters are
switched on and no error messages are given.
