About this model
Model overview
The DTI30M977BB is a 30-inch electric induction cooktop. Published fault codes exist for the Modernist induction cooktop DTI30M977BB, which gives us a useful starting point when something goes wrong: the display reports a letter and number, and the code page explains the area it refers to.
Codes you may see
Our code pages carry these meanings. The A2 code concerns the cooling fan motor circuit. The C0 and C1 codes concern the top sensor being open or shorted, and C2 an open IGBT sensor. D0 appears when a key is pressed for more than eight seconds. The F0, F1 and F2 codes concern communication between boards, the memory chip and the touch circuit, while UP means input voltage that is too high or too low.
Why a code is only the first step
A sensor code can come from a bad sensor or from a wire or connector on the way to it. A fan code may be a motor, a blocked blade or the board. The technician uses the code to decide where to measure, then confirms before suggesting any part.
Without a code
- A zone that heats weakly or cuts out.
- Touch controls that respond late or never.
- Pans that are not detected.
Induction needs magnetic cookware, so test a pan with a magnet first. Our article on induction not detecting a pan goes through that check.
Installation notes
An induction cooktop needs a dedicated supply and clear space below for airflow. A drawer installed too close to the underside can restrict cooling, and a voltage problem in an older building can trigger the UP message. We inspect these during the visit.
Safe checks
- Write down the displayed code.
- Try a different magnetic pan.
- Dry and wipe the glass.
- Do a single breaker reset and see if the code returns.
Burning smell or sparks: breaker off and leave it off.

Planning the visit
Write down the exact code, which zone you were using and what pan was on it. Mention any recent electrical work in the kitchen. These details let the technician arrive with the right tools and a clear first test.
Frequently asked questions
The meanings on our code pages are published for the DTI30M977BB, so they apply directly to this model.
Input voltage is too high or too low. The supply and connections are checked before the cooktop itself is blamed.
A single controlled power reset is fine. If the code returns, it needs a diagnosis rather than repeated resets.
Yes. It is a 30-inch electric induction cooktop.
