Service Action
1)
Change the IPC;
1)
Change the IPC;
1)
Measure the mains voltage& check if it
is inside nominal range plus/minus
tolerance (min 180V max 265V)
2)
If mains line voltage is OK then
replace the power unit board
1)
Measure the mains voltage& check if it
is inside nominal range plus/minus
tolerance (min 180V max 265V)
2)
If mains line voltage is OK then
replace the IPC
Check the frequency of the phase
connected to the IPC. If the frequency
is not (50 ± 2 ) Hz then the cause of
the failure is not due to the appliance.
2)
If frequency is OK, then replace the
IPC
1)
Check if the coil that is showing the
failure is well plugged in the proper
connector.
2)
Replace the coil with a new one (coil
of the same size) .If this does not fix
the hob, then the old coil is still good,
so place it back in the appliance.
3)
Change the IPC
1)
Verify connection of the product the
mains.
2)
Change the IPC
1)
Verify connections (neautral and
phase wires correctly fitted)
2)
Verify filter board and replace it, if
needed
