Fisher twin draw
Intial fault tap light on bottom draw flashing, softener was blocked and fill hose rapidly expanding.
Went back today replaced softener but still appears restricted. Removed again, no water is getting too the dispenser and the inlet hose is still expanding. Cleaned dispenser and removed and cleaned valves.
Have checked operation of top draw to compare and you are getting water flowing throught the dispenser.
Any clues, this softener came with new filter.
