AquaStop Valve Closure Fault
The F69 error code means the AquaStop safety valve on your Miele dishwasher's inlet hose did not close when commanded by the control board. The machine expected the valve to shut off the water supply at the end of a fill phase, but the valve remained open or did not confirm closure.

Answer to continue safely
Is it safe to keep using?
No. A valve that does not close is a flooding risk. Do not use the dishwasher until F69 is resolved. Keep the water tap closed when not actively testing.
Can I reset the code?
Yes. Yes — turn off mains for 10 minutes and cycle the water tap. If the valve was temporarily stuck, it may free itself. If F69 returns, the valve or its control circuit needs replacement.
When to stop immediately?
Stop if you notice: Water overflows onto the floor, The valve does not click (close) even after a reset.
Symptoms You May Notice
Dishwasher overfills or continues filling
Water keeps entering the tub beyond the normal level because the valve has not closed
F69 appears after a fill phase
The code triggers once the control board detects the valve did not respond to a close command
Water may overflow into the base pan
If the valve stays open too long, excess water can reach the base pan and trigger F70 as well
Machine shuts down as a safety measure
The control board cuts power to protect against flooding
Possible Causes
Stuck AquaStop Valve
The solenoid-operated valve is mechanically stuck in the open position — mineral buildup or debris prevents it from closing.
Requires ProfessionalFaulty Valve Solenoid
The electromagnetic coil in the AquaStop valve has failed — it cannot generate the force needed to close the valve.
Requires ProfessionalWiring or Connector Issue
A loose, corroded, or damaged wire between the control board and the AquaStop valve prevents the close signal from reaching the valve.
Requires ProfessionalControl Board Relay Fault
The relay on the main PCB that controls the AquaStop valve has failed in the 'on' position, keeping the valve energized.
Requires ProfessionalHigh Water Pressure
Unusually high household water pressure overwhelms the valve's ability to close against the flow.
DIY PossibleSafe Checks You Can Do
-
1
Turn Off the Water Tap Immediately
Close the shut-off valve under the sink that feeds the dishwasher. This manually stops water intake regardless of the AquaStop valve state.
This is the most important first step — it prevents potential flooding.
-
2
Power Off the Machine
Turn off the dishwasher at the mains. With the water tap closed and power off, no more water can enter.
Leave the power off for at least 10 minutes.
-
3
Check for Overfill
Open the dishwasher door carefully. Check the water level — if it is above the normal fill line (above the door sill), the valve was indeed stuck open. Mop up any excess.
Check the floor and base pan for overflow.
-
4
Power Reset and Test
After 10 minutes, turn the water tap back on and power the machine on. Start a short cycle and listen for the valve clicking closed after the fill phase completes.
If you hear the valve close and the fill stops at the correct level, the issue may have been a one-time sticking.
-
5
Check Water Pressure
If you suspect high water pressure, test by running the kitchen tap fully. An unusually strong flow may indicate pressure above 10 bar, which can overwhelm the valve. A pressure-reducing valve may be needed.
Normal household pressure is 2–6 bar (30–90 psi). Above 8 bar can stress appliance valves.
When to Call a Professional
Contact a qualified Miele technician if:
- The AquaStop valve does not respond to close commands
- F69 returns after every reset
- F69 + F70 appear together — active flooding risk
- Visible corrosion or damage to the AquaStop hose connector
- The machine is under warranty — valve/hose replacement is covered
