Bertazzoni PE244HB / PE304HB / PE365HB U400 error code is a verified, model-scoped diagnostic entry. Unlike a general symptom such as “not heating” or “not draining,” U400 is literal display information documented for the PE244HB / PE304HB / PE365HB family. Do not apply this definition to a different Bertazzoni platform without checking its own manual.
