# Wolf electric cooktop error code E18

### What this one means

The board that switches the appliance's loads, or the one that drives the display, has reported an internal error, on an electric cooktop, a sealed sheet of glass with the entire control under it. 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 relay board behind the appliance
- The control head behind the fascia
- The harness between them
- Power board failure

### Worth doing before you call

- Take everything off the glass, including a cloth or a hot pan lid over the controls
- Switch the breaker off for thirty seconds and back on, and see whether the code returns

### Then what

A board error that survives a power cycle is a part. Which board is worth knowing before anybody orders anything, and the code is what says which.

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.
