Why does the indicator keep flashing after I replaced the filter?

In almost every case it is because the BRITA Memo still needs to be restarted. The Memo in the lid counts down four weeks and only begins a new cycle once you reset it after fitting a fresh cartridge. Skip that step and it simply keeps showing the replacement signal.

Reset the Memo the way the manual supplied with your Brita Marella describes, because the exact action depends on the version of the indicator. Then check that the new MAXTRA+ cartridge sits straight and all the way down in the funnel. If the indicator still flashes or stops responding altogether, the battery in the Memo has most likely run out. Let us know and we will help you sort it out.
