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"
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
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".
