  Pamela EsparzaAug 17, 2025
  If your DuPure Water Dispenser valve is stalled in regeneration, it could be due to several reasons. The motor might not be operating, so replace the motors. There might be no power at the outlet, so repair the outlet or use a working outlet. The transformer could be defective, so replace the transformer. The PC board might be defective, so replace the PC board. The drive gear or drive cap assembly could be broken, so replace the gear or drive cap assembly. The piston retainer might be broken, so replace the drive cap assembly. Finally, the main or regenerant piston could be broken, so replace the main or regenerant piston.

Why does my DuPure Impression Plus regenerate at the wrong time?

  Mitchell ArnoldAug 21, 2025
  If your DuPure Water Dispenser unit regenerates at the wrong time of day, it could be due to a past power outage, so reset the time of day. It's also possible that the time of day displayed is incorrect, so reset the time of day. Alternatively, the time of regenerant might be set incorrectly, so reset the time of regeneration. Check if the control is set at “on 0” or “NORMAL + on 0” and review the regeneration time option in programming.

What to do if DuPure Water Dispenser valve doesn't auto-regenerate but works with REGEN button?

  If your DuPure Water Dispenser valve does not regenerate automatically but does when the REGEN button is pressed, it could be because the bypass valve is not in the normal operating mode. The meter might be disconnected, so reconnect it to the PC board. It's also possible that the meter turbine is obstructed, so clear the obstruction. The meter itself might be defective, so replace it. There might be a programming error, so review the programming. Finally, the PC board could be defective, so replace the board.

Why does the timer on my DuPure Water Dispenser display the wrong time or flash?

  David FreemanAug 29, 2025
  If the timer on your DuPure Water Dispenser does not display the correct time of day, or if the time of day flashes, it could be because the outlet is on a switch, so use an unswitched outlet. It could also be due to a power outage, so reset the time of day; if the power outage was less than 24 hours, reset the time of day and replace the battery. Finally, the PC board might be defective, so replace it.

The PC board might be defective, so replace the board.

What to do if there's no softening/filtering display on my DuPure Impression Plus Water Dispenser when water is flowing?

  Mark FloresSep 5, 2025
  If there is no softening/filtering display when water is flowing in your DuPure Water Dispenser, it could be because the bypass valve is in the bypass position, so put the bypass in the service position. The meter cable might be disconnected, so reconnect the PC board. It's also possible that the meter turbine is restricted or stalled, so remove the meter and check for debris. The meter itself might be defective, so replace the meter. Finally, the PC board could be defective, so replace the PC board.

  If your DuPure Water Dispenser displays an error code, it could be due to several reasons. If the code is #1001, it might be because the valve has just been serviced, in which case you should press NEXT and REGEN for 3 seconds or momentarily unplug the power source from the PC board, or the motor gears are not fully engaged, motor wires are broken, or the motor has failed, so you should check the motor wiring. If the code is #1002, there might be foreign material stuck in the valve, so check the piston and spacer stack for obstruction, or there is excessive piston resistance, so replace the piston(s) and spacer stack assembly. If the code is #1004, the piston might not be in the home position, so press NEXT and REGEN or momentarily unplug the PC board power, the center drive gear reflector...
