3 / (8)
Error code
Description
Possible reason
Communication error between
Touch Control and induction
generator
Touch Control is defect
Er 47
Touch Control – cable is
not attached well or
defective
filter board is defective
temperature sensor shows
overheat of induction coil
cooking zone has
overheat
Measure
decision
Touch Control needs to be replaced
 with further same error check the Touch Control
cable for secure attachment
 replace Touch Control cable
 with further same error
replace filter board
cooking zone needs to cool down
 error display is cancelled after cooling down
( pot boiled dry )

Description
short circuit on power board
defect of filter board
Possible reason
Measure
permanent undervoltage
check mains voltage
⇨ check filter reg. short circuit on fuse track SI 1
/ SI 2
component part defect

no short circuit.
replace filter board!!!!
decision
Short circuit SI 1
⇨ check all IGBT reg. short circuit acc. to
attachment spare part kit.
In case of short circuit;
⇨ replacement of respective
power board right side
Short circuit SI 2
⇨ check all IGBT reg. short circuit acc. to
attachment spare part kit.
In case of short circuit;
⇨ replacement of respective
power board left side
⇨ insert attached 20 A fuse in fuse holder on
filter board.
Note:
If the fuse track was not activated during
short circuit, replace the filter board!

Short circuit SI 2
⇨ check all IGBT reg. short circuit acc. to
attachment spare part kit.
In case of short circuit;
⇨ replacement of respective
power board left side
⇨ insert attached 20 A fuse in fuse holder on
filter board.
Note:
If the fuse track was not activated during
short circuit, replace the filter board!
