# Wolf induction cooktop error code E18

### What this one means

A mechanical or wiring component has been named, rather than a circuit, on an induction cooktop, where the generator under each zone is a power supply in its own right and reports for itself. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.

### What the code covers

A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:

- The part the code names and its connector
- The wiring between that part and the board
- A connection that has worked loose with heat cycling
- Front LO LED not lit during cooking or lit while idle

### Worth doing before you call

- Note whether one zone is affected or all of them — each has its own generator
- Switch the breaker off for thirty seconds and back on, and note whether anything changed

### Then what

A named part is the most actionable thing this archive publishes: it says what to bring. It is still behind a panel that should only come off with the supply isolated.

This code is published for cooktops & rangetops. The [full list of codes](https://wolfmiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
