8. Failure codes
Error codes are a precious aid to diagnostic. Take care to well identify the model to be troubleshooted,
as codes do not always have the same meaning. In the following table there are gathered the codes and
detailed descriptions, showed in the USIF, of the failures that could happen in the appliance from the
IPC side.
The code to be shown on the display is reported with an ‘F’ before (or a ‘C’ for failure number > 80), this
is just to distinguish these two codes.
Note : On hobs with TC software version prior to 3.30, it may occasionally happen that the residual
heat indicator ‘H’ keeps fixed after the glass has cooled down. In such a situation like this,
the ‘H’ is removed by simultaneously touching “+” and “-” keys corresponding to that heater.
