Asko Dishwasher Troubleshooting

1. Error Code “F1” is displayed.
The F1 error code indicates an error with the water heating. Check the heating element in the dishwasher for any possible damages. In case the heating element is damaged, replace it. Also, check if the heat of the water coming to the dishwasher is adjusted correctly. The heat level of the water should be at least 120 degrees Fahrenheit. If the heat level of the water is lower, adjust the heat level accordingly. Check the thermostat for any damages and make sure it is working properly. If the thermostat seems to be damaged, replace it. If the problem still persists, replace the main control board as it might have a defect.

2. Error Code “F2” is displayed.
The water level is too high in the dishwasher. Check the water pump for damages. If the water pump is damaged replace the component. Make sure that the inlet valve is not letting in too much water. Adjust the valve based on your findings to set the right amount of water for your dishwasher. High water level can also be caused by a clogged drain. Check if the drain is clogged and remove it.

3. Error Code “F3” is displayed.
There is a fault with the thermistor. Check the wirings of the thermistor for any loose wire. If the wiring seems to be correct, your thermistor might be malfunctioning. Replace the thermistor.

4. Error Code “F4” is displayed.
An error occurred during filling. In case you find water in the tray under the dishwasher, check the motor housing, the tub, the drain hose or the door for any damages or clogs. Make sure the float is not broken or damaged. In case the float seems to be damaged, replace it. If the float seems to be undamaged, run a test cycle with the dishwasher while removing the lower access panel. During the test cycle, look for leaks. Once you have identified the faulty part causing a leakage or being damaged, replace it.

5. My dishwasher is overflowing.
Check if your drain hose is placed correctly. Check the hose for clogs and clear it. In case you have a disposer installed, always run it before turning your dishwasher on to clean the drain system. Check for any blockages in the rear area of your dishwasher that could prevent your dishwasher from draining. Make sure you have loaded the machine properly and redistribute the load if needed.
