Hi Maria, that happened to me before, after the inspection we founded that 1 or more nozzles were broken doing thea inspection before washing the MMF you can observe under the nozzle that is broke a small cone where the anthracite is going to deposit, and some will be founded in the cartridge filters. The increase of the SDI could be caused by a preferencial way that the water founded ( probably the cause of the broken nozzles) that can happen if the filter stays on service for to long and don’t have a proper backwash.
I can send you some pictures so it’s easier for you to identify it. Just send me a email to
