What it looks like from the kitchen

## The symptom this code usually arrives with

A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

- Induction zone switches itself off
					A zone that stops mid-cook, or a cooktop that shuts down after a long session at high power. On induction that is nearly always the appliance protecting itself, and it costs nothing to confirm.

														One zone stops during cooking

														Everything shuts down together

														A letter-F code on the display

## About Thermador cooktop error code F8

### What this one means

The cooktop has cut its own power to stay within limits. 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 power-limit setting made at installation
- Supply voltage at the edge of range

### What to try yourself

- Check whether the cooktop was set to a reduced power level when it was installed

### Then what

Many built-in cooktops are commissioned at a lower limit to suit the circuit, and it is forgotten by the time somebody complains the boil is slow.

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

This article is based on:

- Official manufacturer documentation
- Internal repair procedures
