What we can confirm

## Code Water filter symbol flashing, from the manufacturer’s own documentation

This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

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.

- Water dispenser or filter symbol
					Little or no water at the dispenser, or a filter symbol that keeps flashing after you have already changed the filter. The second one is a reset rather than a repair.

														Water slow or not dispensing

														Filter symbol flashing after a change

														Water tasting of nothing in particular

## About Thermador refrigerator error code: water filter symbol flashing

### What this one means

The refrigerator is asking for a new water filter, or has not been told that the one you fitted is new. This is a code without a number: the refrigeration columns have no display to put one on, so the appliance signals it instead. This make publishes no numeric codes for its refrigeration at all, and what this one means comes from the manufacturer’s own documentation rather than from us.

### How it shows on the display

There is no number to write down here, so this is what to look for:

- **The water filter symbol blinking on the control display**

### What sets it off

An alarm is deliberately broad — it tells you the cabinet noticed something, not which part is responsible. This one comes on for:

- A filter that has reached the end of its life
- A new filter that is not fully rotated into its housing
- The reminder itself, which on many models has to be reset by hand

### What to try yourself

- Check the filter is seated and fully turned — the lines on the cap should line up with the lines on the compartment
- On models that keep flashing after a change, hold the LIGHT / FILTER button, or the SUPER COOL button, together with the ICE button for three seconds to register the new filter

### Then what

This is a reminder rather than an error, and it is one of the few things on this list that is genuinely finished in a minute. If the symbol clears but the water is still slow, the next thing to look at is the shut-off valve and the supply line, not the refrigerator.

This one appears on built-in refrigerators & columns. 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.
