Repair planning
F04 cost planning: The source-listed safety check is usually €0. €90–€220 is a typical Europe planning range for diagnosis before parts; it is not Hotpoint pricing. Ask for separate diagnosis, parts, labor, and call-out lines on the quote.
F04 time plan: 5–10 minutes to document and isolate safely; 30–90 minutes is a typical diagnostic visit before any model-specific repair.

F04 parts decision: No component should be ordered from F04 alone. The documented fault area is “a thermostat fault”; the technician must identify the failed model-specific part and revision.
What not to do
- Do not open fixed panels, test live circuits, bypass protection, or keep operating the appliance after an urgent stop instruction
- Do not run an extra test cycle after the source tells you to stop or arrange service for F04
Preventive maintenance
- 1Follow the exact Hotpoint maintenance schedule for the dishwasher and keep the model, serial number, and service history available
- 2If F04 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
