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.

Disconnect cooking hob from mains, 
wait 10 sec and reconnect the mains 
supply. 
Should alarm still be displayed, 
replace filterboard.. 

 

"E3“ 

Under voltage or over 
voltage, is only displayed 
for 10 sec. after voltage 
has been applied. 

1) Disconnect cooking hobs from the 
mains, wait 10 sec. and reconnect the 
mains. 
2) Should alarm still be displayed,  
test L1 against N (4),  
test L2 against N (5)  at the mains 
connection

3) If OK, see  
See Chapter  3 Testing Power 
Component 
 
 

 

"E4“ 

Coil temperature sensor 
defect or not correctly 
connected.

(5)

Inspecting the contacts on the 

power component. 
Is the connector inserted? 
2) The resistance at room 
temperature (25°C) amounts to 1000 
Ohm. This corresponds to approx. 3.3 
Ohm per +1°C deviation. 
If not in this range, replace affected 
coil including temperature sensor. 
3) Should above not succeed, replace 
power component concerned.
