My filter media has gelled / stuck together in my K+ Advanced Filter – Evolution Aqua

Switching the Air Blower ON and OFF 2 or 3 times and performing multiple rinses can free up media.
Performing a backwash prior to following the cleaning instructions can free up the media.
Operating the filter on re-circulate will determine if the restriction is in the filter.
If you don’t succeed when following the two points above, switch off the pump, isolate and drain the filter. Manually drain the filter, remove the lid and inspect the inside of the unit. The media may need to be removed and cleaned.
