What does error E4 on Water Right IMP-1054 mean?
- MMelissa PetersAug 31, 2025
If your Water Right Water Dispenser shows error codes E4, Err – 1004, or Err – 104, the control valve motor ran too long and timed out while trying to reach the home position. This may be due to the drive bracket not being snapped in properly, preventing the reduction gears and drive gear from interfacing correctly. Snap the drive bracket in properly, then press the NEXT and REGEN buttons for 3 seconds to resynchronize the software with the piston position, or disconnect the power supply from the PC board for 5 seconds and then reconnect it. Another cause could be that the piston is not connected to the drive cap; connect or replace the piston/drive cap if damaged.
