EKDG 6800.2
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 inter-
rupted.
Evaporator
calcified
Level pin
only develops low resist-
ance when the evaporator is filled up.
(message appears only after the fault
has occurred five times)
In addition to limestoning the following may 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?).
Level pin
develops too little resist-
ance during the emptying process.
(message only appears after several
discharge operations as soon as the
level pin develops resistance again).
Besides calcification the following may also be the cause:
1.
Discharge pump does not transport sufficiently (swivel arm/hose
blocked or crushed).
2.
Wiring to the level pin has a loose contact
3.
Foam in the evaporator casing (unsuitable descaling agent)
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
F1
Food temperature gauge
a) excessively low resistance
b) excessively high resistance
1.
For F1a: Food sensor or the corresponding wiring short
circuited
2.
For F1b: Food sensor or corresponding wiring has a loose con-
tact; socket has a loose contact (deformed contacts?)
3.
For F1a: Food sensor not inserted into the food for the hot-air
mode (sensor tip gets too hot)
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
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
F4
Exhaust air slide motor power
faulty
(too much power during oper-
ation or too low in the final position)
1.
Exhaust air slide sticks due to deposits of grease
2.
Motor jams or races (mechanical system defect)
3.
Corresponding wiring faulty (interruption, short circuit, loose
contact)
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.)
