Repair planning
F12 cost planning: The published button or controlled power check costs €0. Electronic diagnosis is generally planned within €90–€220 before parts; require the exact board revision and separate parts/labor pricing.
F12 time plan: 5–15 minutes for the F12 owner-level check; professional control, communication, or configuration diagnosis commonly takes 30–90 minutes.

F12 parts decision: F12 points to a communication error between the main board and display, but it does not prove a control board is defective. The keypanel, harness, supply, firmware/configuration, and exact board revision must be separated by diagnosis.
What not to do
- Do not spray the controls, hold random key combinations, repeat resets, open the console, or order a control board from F12 alone
- Do not turn F12 into a parts diagnosis
- the display identifies a condition, not a completed component test
- Do not turn F12 into a parts diagnosis; the display identifies a condition, not a completed component test
Preventive maintenance
- 1Follow the exact Hotpoint maintenance schedule for the dishwasher and keep the model, serial number, and service history available
- 2If F12 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
