Fault f76 on model sa-pm38 - Panasonic SC-HT680 System

have a look for all swollen caps and replace as needed
for a start

When power is applied do you get any LED light or display that shows?

F76 is usually a communication error between the remote and the heater. you may have just unplugged something inside the unit while it had power (don't do that). Just unplug the unit from the wall (or flip the breaker) and wait 10 sec and plug it back in again and the problem should fix itself. Otherwise there my be a loose wire going to your remote. In which case, try unplugging the remote and unit for 10 sec and plug the unit (only) back in with the remote disconnected. run your hot water and see if it works. if so it could be a problem with the remote or its wiring.

Usually that is just to wrap around the fan cable to make sure it doesn't go into the fan. F76 error can be either the fan is not turning, or the amp is bad.

I have the same problem with my Panasonic model SAHT-40. I get the same code plus popping and shortly reads maximum overload then cuts off. I disassembled my unit and discovered that my fan fails 2 work causing the unit it over heat. I called Panasonic 2 place an order 4 a cooling fan. This model is obsolete they dont even manufacture parts 4 this unit anymore. The closest that I can get with my credit card is Samsung model AH31-00056B cooling fan through Panasonic. I hope that this solution helps all of u out with ur unit!

there is a problem with the cooler we had the prob too .

Beim Einschalten des Receivers SA HT07 kommt die Fehlermeldung F76 und der Receivers stellt sofort wieder ab. Alle Lautsprecherverbindungen sind ok! Wo liegt das Problem ?? vielen Dank für die Hilfe

Hi,F76 is the error displayed when the fan goes faulty in the unit.
