What does error E4 mean on my Water Right Water Dispenser?
- UuflowersAug 30, 2025
If you're seeing error E4, Err – 1004, or Err – 104 on your Water Right Water Dispenser, it means the control valve motor ran too long trying to reach the home position. Make sure the drive bracket is properly snapped in so that the reduction gears and drive gear interface correctly. Then, press the NEXT and REGEN buttons for 3 seconds to resynchronize software with piston position or disconnect power supply from PC board for 5 seconds and then reconnect.
