6. Checking of possible errors
1) ERROR "F1"
Cause: Freezer probe disconnection or short-circuit
Action: Depending on room temperature compressor cycles as per table below
TA/S ~7°C ~13° C ~19° C ~29° C > 29°C
Compress.
ON/OFF
14 / 50 16 / 41 27 / 45 26 / 22 35 / 20
If freezer probe functions correctly, error F1 is cleared automatically
2) ERROR "r1"
Cause: Fridge probe disconnection or short-circuit
Action: Depending on room temperature compressor cycles as per table below
TA/S ~7°C ~13° C ~19° C ~29° C ~39° C > 39°C
Compress.
ON/OFF
OFF 3 / 50 2 / 10 3 / 7 4 / 6 6 / 6
If fridge probe functions correctly, error R1 is cleared automatically
3) "ERROR "rT"
Cause: Room temperature probe disconnection or short-circuit
Action: Normal operation, inhibition of room temperature probe monitoring (< 13°C)
If room probe functions correctly, error RT is cleared automatically
4) ERROR d1
Cause: Defrost probe disconnection or short-circuit
Action: Timeout (30min) for defrost function reset
If defrost probe functions correctly, error F1 is cleared automatically
5) "DOOR" ERROR ("dF","dR","dH" on display)
Cause: Occurs if door remains open for 1h (after opening)
Action: Inhibition of function connected to detection of door switch
If door switch (opening & closing) is detected, error terminates automatically
6) ERROR C1
Cause: If comp. remains in operation for more than 3 h and defrost sensor detects temperature > -5°C
Action: Check normal operation of refrigerant circuit
Error terminates when defrost sensor detects temp. > -5°C with compr. OFF
7) ERROR F3 (Comp ON, FS fails to decrease = C1)
Cause: Occurs when defrosting is reset after a timeout of 80 min
Action: Inhibition of Pre-cooling mode in defrost mode
If defrosting is controlled by defrost sensor the error terminates
8) MODE "d2" (forced defrost for technical service)
Press REFRIGERATOR SET button 5 times while simultaneously holding down the FREEZER SET
button (after Test Mode)
Action: Forced defrost command for technical service (pre-cooling function is disabled)
If defrost probe detects temperature > 10°C, the mode terminates automatically
ERROR EI
Cause: Ice sensor short circuit or open circuit
Action: Check that after water supply ice drop occurs at intervals of 4, 8, 12 h
Error terminates when sensor normal status is restored
