Cooktop error code UP
Dacor cooktop error code UP: The cooktop is reporting on the supply rather than on itself, and that makes it the one code in this table where the appliance may be entirely healthy. Which machines can raise it, what the maker publishes about it, and what to do next.

What we can confirm
Code UP, 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
UP
The cooktop is reporting on the supply rather than on itself, and that makes it the one code in this table where the appliance may be entirely healthy. In a building with a shared supply, or where a renovation has put an induction cooktop onto a circuit that was never intended for one, this is a real and repeatable finding. It is an electrician's question before it is ours, and we will say so.

What it narrows down to
Input voltage too high or too low — outside the 208 to 240 volt range.

What else belongs to the cooktops and rangetops
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
Top sensor open.
Top sensor short.
IGBT sensor open.
Communication failure between the main and sub PCB.
Communication failure with the EEPROM.
Communication failure with the touch-enabled IC.
Fan motor malfunction — a blocked DC motor, or a problem in the board or wiring.
A key was pressed or held for more than eight seconds — a wet or stuck keypad.

About Cooktop error code UP
What UP means on this make
The cooktop is reporting on the supply rather than on itself, and that makes it the one code in this table where the appliance may be entirely healthy. In a building with a shared supply, or where a renovation has put an induction cooktop onto a circuit that was never intended for one, this is a real and repeatable finding. It is an electrician's question before it is ours, and we will say so.
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
Modernist induction cooktops. 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 it appears at particular times of day — that points at the building supply.
- Check whether other appliances on the same circuit misbehave at the same moments.
- The supply is measured under load rather than at rest, which is where a marginal circuit shows.
- Where the supply is at problem we say so and do not sell an appliance repair.
Where this goes next
The job this usually becomes is diagnostic visit, 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.
