Zünd L-3000CV errors.

[theyllek]

Does anyone have a reference for Zünd error codes that are not in the manual or a wiring schematic? We bought a used L-3000 last year and while we had training form a Zünd tech, it's been a while and not all of the error codes are in the operators manual either.

We keep getting and AC Faults 307 and 309, which are in the operators manual, but not the 330 error. Other than knowing it's in the electrical system we are a little in the dark on where to begin tracing down the problem

Any help appreciated.

Thanks.

In case anyone else stumbles by with the same problem:

After an entire afternoon of sitting down with a master electrician, we were eventually able to trace the problem to a faulty fuse: F1 on the System Function Board.
