Thermador Refrigerator Water Filter Symbol Flashing

What Water Filter Symbol Flashing means

A tiny filter icon blinks on the control panel. According to Thermador's refrigeration troubleshooting page, it either prompts you to change the cartridge or warns that the cartridge is not sitting properly. Some models keep blinking until you press LIGHT / FILTER together with SUPER COOL. The 800-era columns skip the icon and print a sentence saying the filter has to be changed immediately.

Usual causes of Water Filter Symbol Flashing

The cartridge has used up its service life
The cartridge was fitted but not turned fully into place
A fresh cartridge was installed and the reminder stayed on

✓ A safe check worth trying

1. Put in a new cartridge, or take the old one out and turn it back in until it locks. 2. Cancel the reminder using the button sequence in your manual. 3. Watch whether the icon stays dark. 4. If it blinks again, the cancel step was probably missed.

! Why you should stop here

An icon that keeps flashing despite a correct reset points toward the keypad or control, which has to be examined on site.
Reminders are cleared at the panel, so a technician is only useful if the reset itself fails.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

Which buttons clear the reminder?

For certain models Thermador names LIGHT / FILTER together with SUPER COOL, and for the rest it refers owners to the manual, so look up the exact instruction for your model number.

A few drops appear near the new cartridge. Normal?

No. Drips after a change usually mean it is not fully locked in. Turn it until it seats, then dry the area and check again after an hour.

Do older columns show the same blinking icon?

Not always. The 800-era columns display a written message about changing the filter right away, instead of the blinking symbol. Both versions simply mean the filter needs your attention.
