Before you book,
in this order.
Each step comes from Bosch's own guidance for E09 on its dishwashers. Follow it to the end: the last card says whether this is a visit.
Switch the dishwasher off at the breaker for 30 seconds, then back on.
Run a short program and watch whether E09 returns.
If it does, book a visit so the heater circuit can be tested.
Still there?
It usually turns into heating and drying repair. Book with the code and the model number.
What not to do
E09 is not the limescale message. Scale in the heat pump has its own code, E12, which descaling usually clears.
