Question about Asko 24 in. D3120 Dishwasher
If what is mentioned is correct to me, the motor or pump is running at times and you can hear the humming when the machine is plugged on. Your resetting also does not help to get the machine to run the program. It seems to me that the error is in the main program controller unit. It is possible that the processor in the unit has errors and has hung up. Alternatively the processor can also have a corrupt memory and so does not run the desired program.
So if the resetting as done by you does not help , then the controller unit must be changed.
Also check the panel , the connections to the drain and inlet and the door switches before the main controller is confirmed.

This could be due to a faulty motor or control panel. Sometimes, the spray arms doesn't spin due to blockage or low water pressure. Check for any stuck food pieces stuck near the pump impeller. Let me know if there are any blinking lights or error codes.To resolve the issue remove the back plate and check the drain pump. Disconnect the hoses from the drain pump and clear the lint from the hose and the pump area. Lot of water would be ther when you'll remove the hose from the pump, be ready to collect it. Hope this helps... Please post back if you need more information. Daniel

Try first disconnecting power cord or tripping the circuit breaker. Power reset can sort out a jammed control module.
If there is no inlet (no water getting in), then the pressure from inlet hose, the water inlet valve, and the overfill switch must be tested. Water valve is tested reading Ohms at valve solenoid. If the multimeter reads open (Ohms infinity), then the valve must be replaced. (see here how to test). If valve is OK, then the overfill switch (float) must be tested. A way to test the float switch is by jumping its contact and starting a cycle. If all those parts are OK and there is NO water getting in, then the problem is the control module.
If the appliance does not even start cycling, there is noise, and there is water inside the appliance, then the problem is usually overflow detected. The noise is the drain pump starting from beginning of the cycle.
If the dishwasher bottom looks dry either there is water trapped in the corners or in the bottom panel, or the drain hose is set incorrectly, and water is flowing back from the drain line, triggering the overflow device. If there is no water and drain hose is fine you will check the overfill device for faults.
Pull out the dishwasher and check the drain hose height and elbow. Ensure that settings are as specified in the user manual. If elbow height is incorrect you get water flowing back from drain inside the dishwasher. That is detected as overfill.
Remove the drain hose and put it in a bucket, then try tilting the dishwasher 45 degrees backward, secure it safely (ask help if needed) and start cycle, so that water trapped at the bottom can be released. Put the drain hose to correct settings and put back the appliance in place if this solves the problem.
If that does not help, then parts must be tested.
Check the drain well again.Open the housing, and remove water present in there . The overfill switch is connected to the float and can also be responsible of the problem. The switch itself can be tested jumping its contacts or using a multimeter to read Ohms at switch contacts. With contacts jumped no overfill will be detected and machine will start working (stop cycle manually after machine begins filling). Alternatively, remove the part and read Ohms while operating the float arm. The switch must change from a couple of Ohms to infinity (overfill) while you manually operate the arm.
If that does not help, go for the rest. Do not replace parts without testing. Check again inlet hose, check spray arms and impeller. Next step would be reading volts from CCU (central control module), and eventually replacing the control module
Try first tilting the appliance and checking the drain hose.
Disconnect power before performing any maintenance operation.
