On an intermittent problem, **that code may be the only evidence there is** — the machine clears it, runs a normal cycle, and by the time somebody arrives there is nothing to see. A photograph of the display costs nothing and is worth a great deal. ### What the numbers separate F5 pressure system, F7 overheating, F9 divisor position, HI high-voltage supply. They are not degrees of the same problem; they are four different places to look, and knowing which one you have is the difference between an accurate visit and a return trip. ### What is included Diagnosis that clears the supply and the sensing before a board is named, the part, the labor, the panel refitted where there is one, and a full cycle run and watched before the appointment ends. **Exact cost is confirmed after an on-site diagnostic.** What moves this figure Control board, wash pump, pressure system or wiring F5, F7, F9 and HI are the maker's codes for this half Write the code down before you clear it What the code actually says The maker publishes these: F5 is the pressure system, F7 is overheating, F9 is the divisor position, HI is a high-voltage supply problem. Four different repairs behind one row, and the code is the fastest way into the right one. Whether it is the supply rather than the machine HI is about the electricity arriving, not about the dishwasher. That is checked at the outlet before anything inside is opened, and it is occasionally an electrician's job rather than ours. Board availability A board for a current model is ordered against the plate. On an older machine, availability is checked before anything is promised. Whether the machine is built in behind a panel Integrated machines come out of the opening and go back aligned, and the panel is refitted. Planned time.

Because the parts behind it are the expensive ones and the diagnosis that justifies them takes the longest. We will not fit a control board on suspicion. ### The machine shows HI. Is that the dishwasher? Not necessarily — the maker gives it as a high-voltage supply failure, which is about the electricity reaching the machine. It is checked at the outlet first, and occasionally the answer is an electrician rather than an appliance repair. ### It shows a code once and then runs fine. Should I bother? Note it and see whether it repeats. An intermittent code is worth reporting with what the machine was doing at the time; it is the early version of a problem that will eventually stop the machine mid-cycle. --- **[Read full article: Dishwasher control & electronics repair cost](https://bertazzonimiami.support/repair-cost/dishwasher-control-and-electronics-repair/)**
