“i20” Code - family: Draining
Problem
“i20”-Code: Fails to drain
• Acoustic signal and visual error, depending on
the appliance customization; the program can be
restarted
• The level switch restore point is not reached within
the time limit set
• The time limit set starts when the drain pump is
activated
• The time limit set is reset when the drain pump
stops normally
• Time limit set: Normal 90 sec; Test cycle = 60 sec.
“i30” Codes - family: Aqua
Control
“i30” code: water detected from aqua
control sensor
• Acoustic signal and visual error, depending on
the appliance customization; the program is
restarted automatically in this error condition
• If this error condition occurs, the drain pump is
activated
• Time limit set: 10 sec.
“i40” Codes - family: Analogue
pressure sensor problem
“i41” – code: No pressure sensor signal
• The error is set if the sensor signal is lost for more
than 1s
• Abort program and display error.
“i42” – code: Calibration invalid,
pressure signal too noisy
• The warning is set if the sensor signal is not stable
enough for calibration or if the signal is out of
range for an empty sump
• The signal noise level for calibration is defined in
MCF.
“i43” – code: Pressure sensor signal
too high
• The error is set if the sensor signal is out of range,
signal high for more than 1 s
• The signal range is defined in MCF
• Abort program and display error.
“i44” – code: Pressure sensor signal
too low
• The error is set if the sensor signal is out of range,
signal low for more than 1 s
• The signal range is defined in MCF
• Abort program and display error.
“i45” – code: Calibration invalid,
pressure signal too low
• The warning is set if the sensor signal is out of
range for an empty dw, signal low
• The signal range for calibration is defined in MCF.
“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 error, depending on
the appliance customisation; the programme is
suspended
• The washing pump runs without being activated
by the software the cause is short-circuit
• The heating element is not activated
• If the error occurs, the fill Solenoid Valve is
activated up to the level pressure switch tripping
