Check backwash, brine draw, and brine tank fill.
Increase frequency of regeneration. Increase
backwash time.
Clean flow control.
Clean injector and screen.
Replace timer.
Replace brine valve seat and clean valve.
Clean brine line flow control.
Clean drain line flow control.
Clean injector
Clean screen.
Increase line pressure to 30 psi, .20 MPa.
Change seals, spacers, and piston assembly.
Check drive motor and switches.
Determine if switch or timer is faulty and replace
it, or replace complete power head.
Check timer program and positioning of control.
Replace power head assembly if not positioning
properly.
Remove power head assembly and inspect bore.
