What to do if DriSteem 250 control valve does not regenerate automatically when the REGEN button is depressed and held?
- A
  Adam RobinsonSep 10, 2025
  If the control valve on your DriSteem Humidifier doesn't regenerate automatically even when you press and hold the REGEN button, it could be due to a broken drive gear or drive cap assembly, which would need replacement. Contact Dristeem technical support. Alternatively, the PC board might be defective, requiring replacement. For systems with multiple units, another unit already in regeneration might prevent another from starting; wait for the first unit to finish.

Why DriSteem 250 Humidifier control valve uses too much regenerant?
- R
  Roger FosterSep 12, 2025
  If your DriSteem Humidifier's control valve is using too much regenerant, it could be due to an improper refill setting or a refill flow control that isn't sized properly; check the refill setting and ensure the refill flow control provides the correct refill rate. Improper program settings could also be the cause; check the program settings to ensure they are specific to the water quality and application needs. Additionally, frequent regeneration of the control valve could indicate leaking fixtures exhausting capacity or an undersized system.

Why DriSteem 250 Humidifier has residual regenerant being delivered to service?
- S
  samanthapowellSep 14, 2025
  If residual regenerant is being delivered to the service in your DriSteem Humidifier, it could be due to low water pressure; check that the incoming water pressure remains at a minimum of 25 psi. A plugged, fouled, or incorrect injector size could also be the cause; inspect, clean, or replace the injector, ensuring it's the correct size for the application. Lastly, a restricted drain line could be the issue; check the drain line for restrictions or debris and clean it.

Why DriSteem 250 water running to drain?
- C
  Christopher RodriguezSep 16, 2025
  Water running to drain in your DriSteem Humidifier can be caused by a power outage during regeneration, or the unit is currently in regeneration; upon power restoration, the control will finish the remaining regeneration time, and you may need to reset the time of day. It could also be due to a damaged seal/stack assembly or piston assembly failure, both requiring replacement. Additionally, ensure the drive cap assembly is properly tightened.
