We have a Franke Minerva tap, which takes a Franke 7 filter cartridge. The tap was purchased in 2016, but the Minerva Tank was replaced in June 2023 by Franke. When I fit a new filter the kettle tap works perfectly fine, however after about three to four weeks the flow rate reduces to a dribble. Since September 2024, I have replaced the filter twice. The result is always the same. What I have found is that if I remove the filter and allow it to dry out, then once refitted, it works as normal for a few weeks before it slows down again. I don’t know whether it’s a problem with the filter or not, but, given the circumstances described, I’m struggling to see how it could be something else, and I was wondering if anyone else is having issues.
The filters have changed and the notes included with the recent filters say that the change of appearance of the filter is a temporary measure only, due to short term manufacturing supply issues. The note goes on to say that the change should not affect performance.
