Rehoming Reverse Osmosis Solenoid E
Issue: When the Reverse Osmosis (RO) Human Machine Interface (HMI) is showing a RO Pump High-Pressure alarm and when the RO is making twice as much reject water as purified water, solenoid E will not respond to being commanded to either open or close from the RO HMI, we will need to rehome Solenoid E.
Tools needed:
- plumbing pliers
Steps:
1. Locate Solenoid E on the RO system.
2. Remove the screw-on cap.
3. Press and hold the middle button for 5-seconds.
4. It should take 2 minutes for Solenoid E to rehome itself.
5. Screw back on the cap.
If this does not solve the RO Pump High-Pressure alarm, then Solenoid E will need to be replaced.
