# Wolf electric cooktop error code E63

### What this one means

The appliance is measuring its own electricity supply and does not like what it sees, 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:

- A supply running high or low at the panel
- A neutral broken somewhere in the house wiring rather than in the appliance
- The two legs of a 240-volt feed not being two separate legs
- Zero cross lost

### Worth doing before you call

- Take everything off the glass, including a cloth or a hot pan lid over the controls
- Check whether anything else in the house has misbehaved at the same time
- Look at the breaker for this appliance and reset it once

### Then what

This is one of the few codes that is usually about the house and not the machine. An electrician measures the supply; we measure what the appliance did with it.

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.
