Fault schedule
EKDG 6800.1
Signal
Faulty diagnosis of the micro-
controller
Possible causes of the fault
Add water
Water resistance remains high although
the pump is switched on (level pin does
not conduct).
Besides a lack of water in the tank, the following may also be the
cause:
1.
The supply pump does not transport sufficiently (swivel arm/
hose blocked or crushed).
2.
Wiring to the level pin faulty (interruption, loose contact, etc.).
3.
Earth circuit on the evaporation heater or on the calculator
interrupted.
Evaporator
calcified
Level pin
only develops low resistance
when the evaporator is filled up. (mes-
sage appears only after the fault has
occurred five times)
Besides calcification the following may also be the cause:
1.
The supply pump does not transport sufficiently (swivel arm/
hose blocked or crushed).
2.
Water insufficiently conductive (demineralised water used?).
3.
Insulation layer on the pin (unsuitable descaler used or resi-
dues?).
F0
Oven temperature gauge
a) excessively low resistance
b) excessively high resistance
c) Reference resistance excessively low
d) Reference resistance excessively
high
1.
For F0a: Oven temperature sensor or corresponding wiring
short circuited
2.
For F0b: Oven temperature sensor or corresponding wiring
has a loose contact
3.
Computer defect, possibly as a result of moisture
F2
Water temperature gauge
a) excessively low resistance
b) excessively high resistance
1.
For F2a: Water temperature sensor or corresponding wiring
short circuited
2.
For F2b: Water temperature sensor or corresponding wiring
has a loose contact
3.
Computer defect, possibly as a result of moisture
F3
Air temperature gauge
a) excessively low resistance
b) excessively high resistance
1.
For F3a: Air temperature sensor or corresponding wiring
short circuited
2.
For F3b: Air temperature sensor or corresponding wiring has
a loose contact
3.
Computer defect, possibly as a result of moisture
F4
Exhaust air slide motor power faulty
(too much power during operation or too
low in the final position)
1.
Black speed limiter of the exhaust air slide motor deformed
(used until approx. 8/2005). Always replace black speed lim-
iters with natural coloured models, also as a precaution! The
motor may need to be moved in order to mount the new
speed limiter. Hint: Pull out the motor plug while the motor is
running.
2.
Exhaust air slide sticks due to deposits of grease
3.
Motor jams or races (mechanical system defect)
4.
Corresponding wiring faulty (interruption, short circuit, loose
contact)
5.
Computer defect, possibly as a result of moisture
F5
Data backup faulty
a) EEPROM check total faulty
b) EEPROM process data faulty
c) EEPROM read-in faulty
d) EEPROM writing faulty
e) ROM faulty (is not shown on the
appliance)
Computer defect (component error, EMV influences, moisture,
dirt, etc.)
F7
Water temperature does not rise suf-
ficiently
(when the evaporator heater is
activated the water temperature does
not rise sufficiently)
1.
Heater defect, interruption in the flange (overheating protec-
tion device),
2.
Faulty wiring (interruption, loose contact, etc.)
3.
Water temperature gauge does not react (probe plug dirty,
etc.)
4.
Calculator defect (relay, etc.)
