Error code
Dishwasher error code F-8
Dacor dishwasher error code F-8: The two boards have stopped talking, and on this platform the service manual is unusually specific about why: the four-wire harness that runs from the door into the base takes the flexing of every door movement and the moisture of every cycle, and a wet or corroded connector in it is the common cause. Which machines can raise it, what the maker publishes about it, and what to do next.

What we can confirm
Code F-8, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
F-8
The two boards have stopped talking, and on this platform the service manual is unusually specific about why: the four-wire harness that runs from the door into the base takes the flexing of every door movement and the moisture of every cycle, and a wet or corroded connector in it is the common cause. That is a repair to a harness rather than to either board, and it is a fraction of the price.

What it narrows down to
Communication failure — data transfer between the control board and the power board.

On the same appliance
What else belongs to the dishwashers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Inlet valve — after filling, the controller found no water where it expected some.
Circulation pump — the power board saw no relay closure.
Electrical or heater — no temperature rise within the expected time during wash or rinse.
Drain pump — water was still present in the sump after the drain cycle.
Air flow fan.
Controller or floor guard — the leak-detection system has tripped.
EEPROM failure.
Water presence sensor — the WPS that reads water, turbidity and temperature.
Leakage check — a leak has been detected. Shut off the water supply and the breaker.
Water supply check — the valve is closed, the supply is suspended, or the inlet line is blocked.
Drain check — the machine could not empty properly.
High-temperature heating check.

About Dishwasher error code F-8
What F-8 means on this make
The two boards have stopped talking, and on this platform the service manual is unusually specific about why: the four-wire harness that runs from the door into the base takes the flexing of every door movement and the moisture of every cycle, and a wet or corroded connector in it is the common cause. That is a repair to a harness rather than to either board, and it is a fraction of the price.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
EDW and IDW dishwashers. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 5 of the appliance types this site publishes — coffee machine, cooktop, dishwasher, oven and range — and publishes none at all for freezer, microwave, range hood, refrigerator and wine cooler. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Note whether the problem comes and goes with the door movement — that is the harness almost exactly.
- The door-to-base harness and both its connectors are inspected for moisture and corrosion first.
- A dried and re-made connection is tested over several cycles before it is called fixed.
- Neither board is quoted until the harness has been cleared.
Where this goes next
The job this usually becomes is appliance control board repair, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 363-6067 and describe what the panel is doing before booking anything.
