Safe checks, step by step
- 1
Confirm that the appliance is a Bosch dishwasher
No special tools
Record the model number and confirm the display belongs to a dishwasher. Do not apply this page to a Bosch washing machine because Bosch documents E25 or F25 there as a turbidity-sensor fault.
The same visible code can mean something different in another product type.
