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.

- Dishwasher not draining
					Water standing in the bottom of the tub after a cycle. Two of the five causes come out by hand without tools, which makes this the symptom most worth five minutes before booking anything.

														Standing water after every cycle

														A code in the twenties, or an E61 label

														Dishes clean on top, wet and gritty below

## About Thermador dishwasher error code E23

### What this one means

The board cannot drive the drain pump. 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.

### The other ways your machine may say it

The same condition is published under more than one label, because it has been carried across generations of this appliance:

- **E23, E6101, E6102, E6103, E61-02, E61-03, E61** — the same condition, on machines of different ages

### 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 pump
- The circuit that drives it
- The wiring between them

### Worth doing before you call

- Cut power at the breaker for thirty seconds and run one cycle

### Then what

Thermador sends this one to service, and so do we: it is behind the base panel.

This code is published for dishwashers. 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
