Not sure who the culprit is. (Florida) I have a 5 yo Kenmore 350 Softener and a 2 yo AO Smith water heater. Im getting hard water for a month now, I first suspected the softener, I cleaned venturi, screens etc and she is using salt up normally, (no bridge) and drawing the water fine and float is free. I used a resin cleaner twice, It seemed to help slightly but only for a day. The water heater on the other hand has been clunking occasionally when using hot water, I assume from a bed of sediment. My question is, can a mineral build up be defeating the softeners function? My next step would be to drain the water heater, but Im seeing so many opinions that it is a waste of time. So my main question is can the sediments in the water heater be working against the softener, and is a draining recommended.
Softener issue or Water Heater?

No, but draining off several gallons, under pressure, is a good idea anyway.
The WH is not causing hard water.
City water? Resin could be going bad.
Unlikely but worth checking... did somebody operate the bypass valve?

City water, yes, is it unheard for resin to last only 5 years, thanks for your input!

Working in this field for 35 years, resin can last from weeks to decades. It is all about the math. How ppm of chlorine hit the resin...

Drain the water every year to clear debris off the bottom, throw the Kenmore softener in a landfill. 
5 years is about the life expectancy of that unit. Some will last longer, many crash and burn much sooner.
