Answer to continue safely
Is it safe to keep using?
No. The dishwasher will not complete a cycle while F1 is active and dishes will not be cleaned. Running repeated attempts with no water can also stress the wash pump. Resolve the fault before using the appliance.
Can I reset the code?
Yes. F1 can be cleared by turning the dishwasher off for 30 seconds and restarting. However, if the root cause — blocked supply, dirty filter screen, or failed inlet valve — is not fixed, the code will return immediately.
When to stop immediately?
Stop if you notice: The code returns immediately after every reset attempt, No water enters the tub even after cleaning the filter screen and confirming the supply valve is open.
Symptoms You May Notice
Dishwasher stops shortly after the cycle starts
The machine runs the pump briefly then halts, displaying F1, because water has not reached the minimum level sensor within the allowed fill period.
No water audible entering the tub
You can hear the drain pump but no trickling or rushing sound of incoming water, confirming the inlet valve or supply is blocked.
Door remains locked after the fault
Asko models keep the door interlock engaged when an active fault code is present; the door will not open until the fault is reset.
F1 code reappears after a manual reset
Cycling the power clears the display, but F1 returns within seconds of restarting, indicating the underlying supply or valve fault persists.
Possible Causes
Closed or restricted water supply
The shut-off valve under the sink is partially or fully closed, or the inlet hose is kinked, preventing water from reaching the valve.
DIY PossibleBlocked inlet valve filter screen
Sediment and mineral deposits clog the fine mesh screen inside the inlet hose fitting, restricting flow below the required fill rate.
DIY PossibleFaulty water inlet solenoid valve
The solenoid coil has failed open-circuit or the valve body is stuck closed, preventing it from opening when the control board signals a fill cycle.
Requires ProfessionalSafe Checks You Can Do
-
1
Check and open the supply valve
Locate the hot or cold water shut-off tap under the sink connected to the dishwasher inlet hose. Turn it fully counter-clockwise to open. Start a rinse cycle and listen for water entering the machine.
Some Asko installations use a 90-degree ball valve — a lever handle parallel to the pipe means open, perpendicular means closed.

2
Clean the inlet hose filter screen
Turn off the supply valve and place a towel under the connection. Unscrew the inlet hose from the back of the dishwasher or from the valve body. Remove the small mesh screen with needle-nose pliers, rinse under water, and refit. Reconnect the hose and restore supply.
Have a small bowl ready to catch residual water in the hose when you disconnect it.

Reset the fault code
Turn the dishwasher off at the power button, wait 30 seconds, then turn it back on. Select a short wash cycle such as Quick Wash and observe whether water enters the tub within the first 90 seconds.
On D5000 series models you can hold the Start button for 3 seconds to perform a soft reset without disconnecting power.
When to Call a Professional
Contact a qualified technician if:
- Water pressure at the tap is normal but the inlet valve does not open when the cycle starts
- Multimeter test shows the inlet valve solenoid coil is open-circuit or out of specification
- Fault persists after replacing the inlet valve, suggesting a control board wiring fault
