Dacor Modernist Cooktop Code d0: Key Held Down

Low risk · DIY check OK

Code: d0
Appliance: Cooktop & Rangetop
Brand: Dacor
Warranty: 30-day workmanship

What d0 means

A lowercase d0 on a Dacor Modernist induction cooktop, such as the DTI30M977BB or DTI36M977BB, means the control sees a touch key pressed for more than 8 seconds. Usually something is resting on the keypad or the glass around it is wet, so the cooktop treats the touch as stuck. The display shows d0 and the cooktop may ignore your other touches.

Common causes of d0

Water or spilled liquid on the keypad
A pan, towel or utensil resting on a key
Residue making a key read as held
The touch keypad or its circuit

✓ One safe check you can try

1. Turn the cooktop off if it responds, then wipe the keypad area dry. 2. Remove anything resting on or near the keys. 3. Restart the cooktop with the POWER key. 4. If d0 keeps showing with a clean, dry keypad, schedule service.

! Why to stop there

Whether a key reads pressed with nothing touching it
Whether moisture got under the glass at the keypad
Whether the touch circuit needs replacing, priced in writing before work

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

d0d0 questions

Why does d0 show up while I am cooking?

A spill or a pan near the controls can make a key look held down. After 8 seconds of that, the cooktop shows d0. Wiping the glass dry and restarting with POWER often resolves it.

Does d0 mean the cooktop is broken?

Not usually. It is one of the milder codes, tied to a key reading as pressed. If it comes back on a clean, dry surface, the keypad itself should be tested.

What do you check if it keeps returning?

We test each touch key and its circuit for a false press, and look for moisture under the glass. You receive a written price first, and the repair has a 30-day workmanship warranty.
