13.3 Interference filter on T780 – T1040/H
The interference filter is arranged on a separate printed board.
Older units have no fuses. The interference filter coil can be
interrupted in case of a short circuit.
If the fuses are blown there is usually a short circuit in the
heating element.
In order to find the cause we recommend to interrupt the cables
of the heating and to test the unit again with new fuses.
