- D
  Dana FordAug 21, 2025
  If your SENTRY II Water Dispenser control valve only regenerates when you manually hold the REGEN button, it could be due to several reasons: * The bypass valve might be in the bypass position. Turn the bypass handles to place the bypass in the service position. * The meter might not be properly connected to the circuit board. Connect the meter to the three-pin connection labeled METER on the circuit board, ensuring a secure connection. * The meter turbine might be restricted or stalled. Remove the meter and check for rotation or foreign material. * The programming might be incorrect. Check for programming errors. * The meter might be defective. Replace the meter. * The circuit board might be defective. Replace the circuit board.
