5 In case of fault
If your device does not function as intended, it is usually due to a small
detail. Please check whether or not the fault can be self-repaired
according to the following indicators. You will thereby avoid the costs of
an unnecessary repair service.
In normal operations, the LED “anode” is constantly lit, the LED
“service” is off.
If one of the two LEDs flashes, this indicates an “error condition”.
In case of fault, do not disconnect the power supply line.
In order to possibly remedy the error condition oneself, there are two
procedures:
RESET : To begin with, please reset the device RESET. To do this,
proceed as follows:
Firstly, turn the dial to the setting ” ● ”.
After that, press the “fast-heating” button .
If the cause of the “ error condition ” does not exist directly after the
reset, the device will again return to its normal mode of function.
Otherwise the device will again indicate an “
error condition ”.
Diagnostic routines : In order to better define the “ error condition ”, the
device uses diagnostic routines. Please activate the program as follows:
Push and hold the button “fast-heating” for at least 5 seconds.
The type of fault will now be displayed by the 6 hot water content LEDs
as presented in the following table:
