The same Bosch code on more than one appliance
Bosch uses these codes on more than one of its appliances. Read the one for your machine: the cause and what you can check are the maker’s for that appliance, and they can differ even where the fault sounds alike.
E01: dishwasher — heat-pump motor circuit fault; tumble dryer — blocked fluff filter or heat exchanger.E03: dishwasher — main control board relay fault; tumble dryer — water container full.E04: dishwasher — heater electronics fault; tumble dryer — load too big.E06: dishwasher — door sensor circuit fault; tumble dryer — fluff filter blocked.E16: dishwasher — water cannot get in; washing machine — door not locked; tumble dryer — door opened during a cycle.E17: dishwasher — water cannot get in; washing machine — water not coming in fast enough.E18: dishwasher — water level too low; washing machine — not draining.
Switch off and unplug before checking. Anything electrical, anything to do with gas, and any water leak at the mains: call a technician. Two Bosch models can use different codes: your model’s manual is the authority.
