These Dacor cooktop communication failure codes appear on the Samsung-era Modernist induction cooktop platform — models like the DTI36M977BB — documented directly in the “Information codes” section of the cooktop’s official user manual.
F0: main to sub PCB
F0 means communication has failed between the main and sub printed circuit boards, mirroring the same main-to-sub relationship documented for the range and oven platforms, though on the cooktop this is specifically an F-prefixed code rather than the C-F0 used on ranges and ovens — the two platforms share the underlying board relationship but not the exact code string.
F1: EEPROM communication failure
F1 flags a communication failure specifically with the EEPROM, the memory component storing the cooktop’s configuration and calibration data. This is distinct from F0’s broader board-to-board failure, narrowing the problem to the memory chip and its connection rather than the general control-board link.
F2: touch-enabled IC communication failure
F2 means communication has failed with the touch-enabled integrated circuit — the chip interpreting input from the glass-surface touch controls. A cooktop displaying F2 may still be heating correctly on whatever setting was last active, while becoming unresponsive to any further touch input, which is a useful distinguishing symptom from F0 or F1.
Why all three are documented as high severity
Unlike sensor failures such as C0 or C1, which affect a single heating zone’s temperature reading, a communication failure between core control components can affect the cooktop’s ability to safely regulate any zone at all, which is why Dacor’s own manual documents F0, F1, and F2 uniformly as high-severity conditions rather than a nuisance problem.
What this table does not include
An unverified claim exists online for a “Heritage electric cooktop” F0/F1/F2 table, reusing wording nearly identical to the Legacy Classic wall-oven error codes. No dedicated Legacy-era cooktop service document was located to confirm this table independently, and it should not be confused with the verified Samsung-era induction cooktop codes above, which come from a different manual entirely and describe entirely different problems.
When to book service
Any of F0, F1, or F2 recurring after a power cycle points toward a board- or component-level problem rather than something resolvable by resetting the cooktop, and is worth an experienced technician’s diagnosis. Our cooktop error codes page lists the full nine-code table for this platform, and our cooktop appliance page covers the current induction and gas lineup.
