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 will not recognize the pan
					A zone that beeps and switches off, or never starts, with a pan sitting on it. A magnet settles this in two seconds and no repair will change the answer.

														Zone beeps and shuts off with a pan on it

														Some pans work and others do not

														A wireless probe reporting instead of the cooktop

## About Thermador cooktop error code E8204

### What this one means

The wireless cooking sensor is nearly out of battery. 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 sensor’s battery

### What to try yourself

- Change the battery in the sensor

### Then what

The cooktop is fine. The probe is a separate device with its own power.

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
- Technician repair history
- Company quality standards
