Alarm Codes
•
i46
code: Calibration invalid, pressure signal too high
•
The warning is set if the sensor signal is out of range for an empty dw,
signal high.
•
The signal range for calibration is defined in MCF.
•
i50 Code - family : Washing Motor Problem
•
i51
code: Asynchronous motor problem
•
Acoustic signal and visual alarm, depending on the appliance
customisation; the programme is suspended.
•
The washing pump runs without being activated by the software, the cause
is a short-circuit.
•
The heating element is not activated.
•
If the alarm occurs, the fill solenoid valve is activated up to the level
pressure switch tripping point, then the cycle is suspended.
•
Time limit set: 8 sec.
•
i52
code: WP BLDC motor – abnormal high current detected
•
Hardware supervising – will be set when abnormal high current of about
1.3 amps are detected.
•
i53
code: WP BLDC motor – over current
•
Alarm will be set when the current is detected higher than the max allowed
current of 1.0 A
•
i54
code: WP will not follow / rotor is locked
•
Alarm will be set when the motor locked condition is detected during start
of motor and also during the running motor; reasons can be dirt, too high
load, mechanical problems on impeller.
•
i55
code: DCLink undervoltage
•
Alarm is set when the Vbat voltage on motorcontrolboard will be detected
lower than 225 VDC and will be cleared if voltage is greater than 260 V DC
•
i56
code: DCLink overvoltage
•
Alarm is set when the DCLink voltage on power controlboard is greater
than 392 VDC and will be cleared when dropping under 390 VDC.
•
i57
code: MCB Vbat voltage plausability / ADC Fault
This code has different meaning depending on platform.
DIVA 2 MCB Vbat voltage plausability
•
Alarm will be set if Vbat is detected higher than 440V or lower than 215V.
rem.: with Vbat voltage the calculation of the motor resistance is
executed.
PB100 Drain pump ADC fault
•
Alarm will be set if the difference between current samples are less than
0.03363 [A] for 0.5 s.
•
i58
code: WP motor plug connection
•
Alarm will be set if motor connection is detected wrong based on motor
currents measurements.
If currents are inside the thresholds (+/- 21 mA); debounce is set to 1.5
seconds.
•
This code is also possible if a phase is detached or if a winding inside the
motor is broken.
