Bosch dishwasher E09 points to internal heat-pump heater fault. Start with the safe checks that apply to this system and stop if the warning returns.
Model compatibility: Bosch reuses codes across series and model years, so E09 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Why it happens

Important safety warning. Keep the dishwasher off if there is overheating, electrical odor, smoke, or repeated power interruption.
