DD24DCTX9NDD24DHTX9NDD24SAX9NDD24SI9NDD60DCHX9DD60SDFHX9
Likely Causes
  1. Water inlet valve is stuck in the open position, causing continuous water fill
  2. Inlet valve solenoid is receiving power but not responding mechanically
  3. Control board inlet valve circuit is sending incorrect signals
  4. Valve diaphragm is worn and not sealing properly when de-energized
How to Fix It
1
If water is continuously filling, immediately turn off the water supply faucet behind or under the unit
2
Disconnect power and test the inlet valve solenoid for proper resistance (500-1500 ohms)
3
Check if the valve shuts off water when power is disconnected; if water still trickles in, the valve is stuck open mechanically
4
Inspect the valve diaphragm for wear or debris on the seating surface
5
Replace the water inlet valve assembly if it is stuck open or the diaphragm is worn
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
