What to do if my ProMinent ProMix S shows 'No Water STOP'?
- W
  William AdamsAug 9, 2025
  If your ProMinent Mixer displays a 'No Water STOP' error, there are several potential causes. First, if it's a flowswitch or differential pressure switch issue, temporarily bypass the controller by connecting the Interlock input terminal ‘FS’ to the adjacent Ground symbol terminal while you troubleshoot. Second, check if the solenoid is activating during the Filling Mixer and Flow Check states by loosening a downstream union. Finally, if there's no AC solenoid power, check the solenoid wiring and coil for shorts, and replace the solenoid fuse (the brown 2.5A fuse in the white socket above the Neutrals terminals; www.digikey.com Part# 7500413). Note that the mixer motor start relay coil shares this fuse.

How to fix 'No Control STOP' on a ProMinent Mixer?
- D
  Don SmithAug 26, 2025
  If your ProMinent Mixer displays a 'No Control STOP' message, switch the On-Off-Remote to On while you troubleshoot the 4-20mA current loop connected to mA In input terminals ‘I+’ & Ground terminal. If the ProMix S mA In 24V is powering the loop, check Polymer / Diagnostic to ensure it reads >23VDC.
