Quick answer
E18 on a Bertazzoni dishwasher: plain-language overview tied to a temperature-sensor issue — not factory service literature.
Model compatibility: Bertazzoni reuses codes across series and model years, so E18 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
