5.4 Fault codes.
In the event of a fault in the appliance, the message “Err” appears in the
display in combination with a digit from 1 to 8 and a fault code. The red
LED next to the info push-button will also light up.
“Err 1” means that there is a fault in appliance 1;
“Err 2” means that there is a fault in appliance 2. And so on…
The fault code indicates the type of fault. The chart below lists and
explains the possible faults.
If fault codes are active for multiple appliances, the blue info button and
the up and down button can be pressed in order to scroll through all the
codes.
Pressing the Reset push-button clears the fault code display, following which the main screen will
appear again.
