Nana – sounds like normal operation. Cycling of the unit back-flushes the minerals filtered (collected) by the resin (the active material of a water softener). After backflushing, it recharges the resin with the use of salt, and then puts the unit back in service.
If your unit has a timer, it may work one of two ways: by passage of time only, or by volume of water and cycle at a specific daily time after that volume has been reached.
Another type (Kinetico) has no timer or electrical connection, has two units and one tank, and cycles by water use and water power.
Hope this explains it for you.

I have had the same (and more) problems with my Generac 2300/2.9gpm Pressure Washer. First the unloader valve caused erratic or non-responsive pressure when the trigger was used. A year later, the pump did a “crash n’ burn” act, but it is working perfectly now.
1) The original unloader valve seal/washer was a “cup” design. Manufacturer re-designed it to two washers (stacked to seal the split in the washers), and it worked flawlessly, for an out-of-pocket roughly (vaguely remembered) $12.
2) Even though the machine “said” it had ceramic pistons (3 of them). The TH series pistons are chrome or polished stainless, and disintegrated in a short time (hours of use).
I recently replaced the oil and piston seals, lubed with water-proof silicon grease for seals, and replaced the pistons with new ones, which fortunately I still had some warranty time left and got from them through the manufacturer, but I had already outlayed $55 for the seals.Here’s what I would do next time: Search for a General CPH3020/CPH3025 replacement pump (has ceramic pistons). A new pump can run you between $150-$210 mail-order (do a search).
If I rebuild this one again (I won’t) I would have to spend about $100 for pistons (part #5704102), and $55 for seals — That does not cover the cost of replacing the 6 check valves that stage the pressure through the 3 pistons.Good luck y’all
