Alarm Codes
Technical Support – A.R. Chapter 4
Alarm management
Alarm codes are defined in families of alarms and current
alarms, displayed as
iXY
•i = alarm indication
•X = family of the alarm
•Y = Current alarm
Caution:
Only the alarm family codes are displayed to the user in old
production. Full alarm codes are shown to user now.
The complete alarm code will be stored among the three alarms
that can be stored by the appliance.
A new alarm code is only stored if it differs from the last one
stored.
The three most recent alarm codes can be displayed only in
Service Mode or using the Sidekick tool.
Appliances without a display will show the alarms by a number
of flashes of the cycle end LED, such as in “DIVA”: i10=1 flash,
i50=5 flashes, iB0=11 flashes.
Alarm Code Description
• i00 Code family: Low mains voltage
The electronic board makes sure the dishwasher operates within certain
voltage limits. If during a cycle the voltage drops below the lowest limit, the
electronic board suspends all loads and interrupts the cycle under way.
The “i00” alarm is then triggered.
• The lowest main voltage threshold is 180 Volt.
• If the voltage goes back to over 186 Volt, the electronic board cancels the
error status and the cycle resumes. The “i00” alarm is also deleted.
• If the mains voltage continues to exceed the maximum threshold, the
electronic board does not do anything.
IMPORTANT: the “i00” alarm is not stored and cannot therefore
be read in Service Mode.
• i10 Code - family : Water Tap Closed
i10 code: during static filling
This alarm code is used to display problems with the water inlet tap being
closed at the beginning of the program. It is set up to detect problems
during the static water filling. A drain phase is performed before the error is
displayed to the user.
• Acoustic signal and visual alarm, depending on the appliance
customization; the program can be restarted.
• The water level defined is not reached within the time limit set.
• The time limit set starts when the fill solenoid valve is opened.
• The time limit set is reset when the fill solenoid valve is closed.
• The water will first be drained before an error is displayed to the user.
• Time limit set: Normal 90 sec; Test cycle = 30 sec (times could differ as
they are defined in the MCF)

customization; the program is restarted automatically in this alarm
condition.
• If this alarm 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 2,5s.
• Abort program and display error.

• 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 2,5 s.
• The signal range is defined in MCF.
• Abort program and display error.
•i44 code: Pressure sensor signal too low
