1 General Information
These instructions serve the repairing of autarkic cooking hobs and cooking hobs in combination with
an oven with 3 or 4 inductions cooking zones respectively of the type E.G.O.. Also includes hobs with
2 induction zones (Domino, Mixed, Mixed gas) and the Frontline appliance series.
Please search for the corresponding alarm
symptom and then go through the alarm remedy measures from top to bottom.
Information concerning the replacement of parts is to be found in the corresponding replacement
instructions or are included with the spare parts.
All work is only to be carried out on the induction modules and the heating elements are only to be
carried out after they have been disconnected.
1.1 Leak current
A leak current of 5mA is normal and is therefore much higher than with other appliances.
1.2 Standby
The Standby power consumption amounts to < 1W (Induction plus user interface in the autonomous,
exception Frontline up to 2W).
The µprocessor for the measuring of the coil temperature is deactivated in standby, i.e. should the
cooking hob be heated up to hot pan being on the zone, no heating display "H“ is displayed when
switched off.
In this condition, the ventilator is also not switched on by external heating.

applied
None Electronic system no

Disconnect the appliance from the mains
using the house fuse, reactivate after
approx. 10 sec..

zone with not self-
sufficient cooking
zones or front line
appliances.
No mains voltage or
incorrect connection
(1 phase missing ->no
control voltage; N not
connected to terminal 4
and 5 not connected)
(1) Test the pin assignment and
230VAC between 4 N and the 2 phases
on supply line terminals 1 and 2.
Both of the "N“s should be connected to
terminals 4 + 5, if appr. jumper.
No 5VDC betw. Pin 1 +
3 of the Bus for the
Touch Control
(2) Test 1+3 5VDC on the underside of
the cooking field
(corresponds with the external lines of
the bus between filter and Touch
Control), if not applied, replace the
Filterboard.
Caution: this is difficult to test from
underneath using normal test probes!

(3) Test connector at the filter and Touch
Control.
Reapply the mains voltage.

If 5VDC exist and power component already
replaced: replace

None N not connected to
terminal 4 or 5.
(1) Test the pin assignment and
230VAC between 4 N and the 2 phases
on supply line terminals 1 and 2.
Both of the "N“s should be connected to
terminals 4 + 5, if appr. jumper.

2.3 Alarm message "E“
When the appliance is switched on, "E“ / „xx“ Alarm Number is displayed in the timer display. With
Frontline the display of the front zone indicates the error number when switching on. The affected
zones are subsequently displayed with an "E" in the cooking phase display and are thereby disabled.
The other zones can still be used.
