What does error 104 mean on my Lancaster Water Dispenser?
- J
  Jack WhiteSep 15, 2025
  Error 104 on your Lancaster Water Dispenser indicates that the control valve motor ran too long and timed out trying to reach the home position. This is often because: * The drive bracket is not snapped in properly, preventing the reduction gears and drive gear from interfacing. Snap the drive bracket in properly, 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.
