Error and alarm messages
Should the control system have recognized a fault, it will firstly switch off all of the consumers and
indicate a corresponding A-alarm message or F or U-fault message.
There are four groups of fault messages which, depending on the reason for the fault, can be rectified
by users themselves or by skilled customer service staff only:
•
Reference messages
are usually not an indication of a defect in the appliance; instead, they request that the user takes
some kind of action. A procedure in operation is only interrupted if this becomes necessary.
Reference messages are indicated by a respective test on the display, e.g. “fill up water”, “close the
door”, etc.).
Acknowledging an A-alarm message
In the case of the “install the water tank”, “fill up water” and “please close the door” messages, the
current program will be discontinued until the fault has been rectified and the OK button has been
pressed. The “water is being pumped off” message goes off by itself once the pumping procedure
has been completed or a new program has been selected.
•
A-alarm messages
are faults which users can rectify themselves and which would have a negative effect on the
appliance or put it out of working order if not rectified. The EKDG 6800.0 only has one A-alarm
message, which can only occur at the end of a procedure and which is indicated by means of the text
“Boiler scaled. Please descale!” on the clear text display. An “A10” fault, unlike U and F fault
messages, is not indicated.
Acknowledging an A-alarm message
A-alarm messages can always be acknowledged by pressing any button. Should the fault still occur,
the next procedure will be followed by a renewed alarm message.
•
F-fault messages
indicate defects which can usually only be rectified by the KÜPPERSBUSCH customer service and
which would put the appliance out of working order if not rectified (defect sensors or actuators, etc.).
They can occur at any time and will immediately interrupt any procedure which is in operation.
F-fault messages are shown in the clear text display as “call Fx Service”, with “Fx” blinking and “x”
being a number between 0 and 9. With the ZUG eye, customer service can find out exactly why the
fault occurred.
Acknowledging F-fault messages
F-fault messages are acknowledged by pressing any button. The acknowledgement will only be
accepted when the fault no longer occurs. Otherwise the fault message will be indicated again, either
immediately or during the next procedure.
•
U-fault messages
indicate defects in the network which can usually only be rectified by customer service or by an
electrical technician. They are only indicated when the controls have been reset (for example, a
power cut or connection to the mains). Mains interruptions during operation are not indicated.
U-fault messages are shown in the clear text display as “Ux El. connection error”, with “Ux” blinking
and “x” being a number between 1 and 4. With the ZUG eye, customer service can find out exactly
why the fault occurred.
Acknowledging U-fault messages
U-fault messages cannot be acknowledged; they disappear by themselves as soon as the fault has
been rectified.
