Possible Causes

Defective AquaStop inlet valve, Debris preventing valve from closing, Faulty control signal keeping valve energized, Stuck relay on control board

How to Fix / Troubleshooting

Safety first: Immediately close the water tap and disconnect power to prevent flooding.

E16 indicates uncontrolled water intake.

  • Step 1 – Check AquaStop hose:
    • Inspect the AquaStop inlet hose for damage.
    • If water continues to flow into the dishwasher when power is off but tap is open, the valve is mechanically stuck open.
  • Step 2 – Replace AquaStop:
    • Turn off the water tap.
    • Disconnect the AquaStop hose from the tap and dishwasher.
    • Install a new Siemens AquaStop hose of the correct type.
  • Step 3 – Control check (if valve only opens with power):
    • If the valve only misbehaves when powered, the control board may be energizing it incorrectly.
    • Inspect the control board for a stuck relay; replace the board if necessary.

Always test for proper filling and shutoff after replacing the AquaStop to ensure no risk of flooding.
