F0 on a Dacor Modernist induction cooktop means communication between the main and the sub PCBs failed. The two boards share the work of running the zones, and F0 says the link between them broke. Dacor cooktop display What to do when F0 shows on the cooktop ### Kind of code Boards and communication The touch board and the power board under the glass lost track of each other, or one failed its own start-up check. A power dip, a ribbon or harness pulled loose when the top was fitted, or moisture from a boil-over is ruled out before a board is replaced, and a cooktop that keeps heating while this code shows is switched off at the breaker. ### Usually leads to Touch control repair Glass touch keys and sliders that ignore a finger, start zones by themselves or stay locked, traced to the keys, the control board or the lock setting. ### Shows up as Cooktop Controls Unresponsive Touch keys or a slider do nothing, the display lights but ignores every press, or a knob turns without starting its burner or element. ### Make Dacor A luxury make, part of Samsung, whose built-in cooktops show up in higher-end US kitchens. ### Source Dacor Modernist induction cooktop user manual, Information codes Dacor Modernist induction cooktops DTI30M977BB and DTI36M977BB (manual dated 2017).

Follow it to the end: the last card says whether this is a visit. 01 Restart the cooktop with the POWER key. 02 If F0 continues, disconnect power for more than 30 seconds and restart. 03 Book a visit if the code returns. ### Still there? It usually turns into [touch control repair](https://cooktoprepair.center/services/touch-control-repair/). Book with the code and the model number. ### What not to do F0 does not point at a key or a zone. It is the link between two boards. ## What you may notice with it.

Restart the cooktop with the POWER key. If it comes back, it needs a visit. ### What causes F0 on a Dacor induction cooktop? A loose or damaged cable between the main and sub boards, or a failing board. The cable is checked first. ### Will a power reset fix F0 for good? If a one-time glitch caused it, yes. A code that keeps returning needs the boards and harness tested. ### Which boards does F0 concern on a Dacor Modernist induction cooktop? F0 names the main PCB and the sub PCB, the two boards that share the work of running the zones. The code says the link between them failed, so both ends and the cable joining them are tested. --- **[Read on the site: Dacor induction cooktop showing F0 | CooktopRepair.center](https://cooktoprepair.center/error-codes/dacor-f0/)** **[Book a visit with CooktopRepair.center](https://cooktoprepair.center/schedule/)**
