Bosch SHEM78ZH5N

Model # SHEM78ZH5N

The SHEM78ZH5N is the SHEM-generation 800 Series that carries CrystalDry as well as PureDry, at 42 dBA over 16 place settings with Home Connect. It is one of the first American Bosch dishwashers to have the zeolite drying module fitted, which makes it a useful reference point: the technology is now old enough to have a service history, and in that history the mineral itself has not been the failure point. The fan, the duct and the flap that opens to the module are what get looked at.

FAQ

Bosch SHEM78ZH5N FAQ

In service we do not see the mineral itself as the failure. It regenerates with cycle heat. What fails, occasionally, is the fan or the duct that moves air across it.

A gradual decline usually means airflow - a partially blocked duct or a tired fan - rather than an abrupt component failure. It is a targeted check rather than a big job.
