I40" Code Family: Analogue Pressure Switch; I50" Code Family: Washing Motor Problems - Electrolux ProClean RealLife EDW5xx Series Service Manual

9.2.5

"i40" code family: analogue pressure switch

9.2.5.1 "i41" code
- The alarm is defined if no signal is detected from the analogue pressure switch for more than 1 sec
or if the signal is out of range.
- The programme stops and the error is displayed.
9.2.5.2 "i42" code
- The alarm is defined if the signal originating from the sensor is not stable enough or is out of range
for an empty appliance.
- The calibration is performed during the activation of the drain pump and immediately after to
guarantee that if the non-return valve is not sealed, the backflow of water does not corrupt the actual
calibration.
9.2.6

"i50" code family: Washing motor problems

9.2.6.1 "i51" code – asynchronous motor
- 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.
9.2.6.2 "i52" code – synchronous motor
- The alarm is signalled when an abnormal extra current of 1.3 Amps is detected.
9.2.6.3 "i53" code – asynchronous motor
- The alarm is signalled when a current above the maximum limit allowed of 1.3 Amps is detected.
9.2.6.4 "i54" code – inverter motor with rotor locked
- The alarm is signalled when the motor is locked at the start or during its actual activation.
- Possible causes may be the presence of dirt, too large a load, mechanical problems on impeller.
9.2.6.5 "i55" code – motor control board over voltage
- The alarm is signalled when the voltage detected on the motor control board is more than 400 V.
9.2.6.6 "i56" code – motor control board under voltage
- The alarm is signalled when the voltage detected on the motor control board is less than 255 V.
9.2.6.7 "i57" code
- The alarm is signalled if a voltage of more than 440 V or less than 215 V is detected.
9.2.6.8 "i58" code – washing pump connection
- The alarm is signalled if an incorrect connection of the pump is detected, based on the current
measurements check.
- Time limit set: 2 sec.
9.2.6.9 "i59" code – current measurement error on motor control board
- The alarm is signalled if there is an error in reading the current on the motor control board
- The condition is verified by the sum of currents of each of the phases, which should be nearly zero:
if this sum is more than 40mA for longer than 300 msec then an error condition occurs.
