1.
Unsuitable pan
, e.g. loss of
magnetic properties through
the temperature of the base.
2.
Hardware fault
: If the inter-
mediate circuit voltage is too
high, the appliance will be
prevented from switching on
and an error display will
appear on the TC. If measu-
ring the current results in
implausible readings, e.g.
current readings when the
appliance is switched off, the
cause is likely to be a HW
problem on the A/D pin of the
controller.
The pan generates an invalid opera-
ting point on the IHE* and this may
result in the destruction of IHE* com-
ponents (e.g. IGBT).
1. This error will be reversed after 8
seconds and the cooking zone will
be ready for use again. If the error
occurs regularly the pan will have
to be removed.
2. If the error also occurs without a
pan or with a pan that is clearly in
good working order, the IHE* will
need to be replaced as a hardware
error will have occurred.
E / 4
Unconfigured IHE or no com-
munication between UI and IHE
1. IHE* not configured.
2. Two or more IHEs* have the same
configuration.
3. IHE* has not been connected to the
power supply, filter board does not
release voltage (power disconnect
relay).
1. Allocate IHE* via the configuration
menu or configure IHE* by means
of IR programming.
2. Delete all the configurations and
configure.
3. Check voltages and the proper
connection of the filter and the IHE*
and connect if necessary.
4. Replace the IHE* if none of these
remedies solve the problem.
E / 5
Component fault
• Controller data faulty
• IHE* electronic unit defect
Replace IHE*.
E / 6
Power supply fault
Component fault
Voltage recognition defect
IHE* electronic unit defect
Check voltages and power supply
Replace IHE*.
