Asko Dishwasher DW20.1 d3120 Water not coming through inlet valve. I have replaced the inlet valve - solenoid only releases when on/off switch and start button are pressed and released simultaneously. A burst of water comes out at that point and stops. What could be wrong?

    ASKO Dishwasher 20.1 d3120. Water only comes out of the inlet valve in bursts when on/off swith and start button are pressed and released.

    I have replaced the inlet valve and tested the water supply. It seems to me that it is more to do with the signal that the solenoid in the inlet valve is receiving. It only operates when the on/off switch and the start buttons are pressed and released simultaneously - it just lets out a short burst of water. Any ideas - could it be the on-board processor if it has one?

    Looks like cockroaches were living in the control unit. Cleaned it but still didn't work. Do you know where I could buy a new control unit?

    Many thanks

Hi, Welcome to FixYa. I'll start by saying your description sounds exactly like a symptom of a faulty control board on Asko dishwasher's...specifically the relay responsible for energizing the fill valve. It sounds to me like the relay itself is receiving power, but then immediately failing which manifest in the manner you describe...water valve energized for a second then nothing. At the stage you seem to be at I would suggest removing the door panel and observing the relay ( they are clear so you can visually see the contacts open & close ) the wiring diagram should identify the inlet relay as "K3" or "K4" I don't recall off hand and I don't have the schematic in front of me. Let me know what you observe or if you require further assistance and I will try and be available asap. P.S. It could also simply be a poor wire connection on the board, power switch or door switch so check thoroughly. Good luck. Macmarkus :)

    Hello again,

    Darn roaches !

    Did you observe any chewed wires or something else ?

    I know most of the Asko part`s I purchase are through a local part vendor, their website is "".

    I would also suggest looking at "" as they do seem to have your Asko part # 8801286, though I confess to never have purchased any Asko part`s from that paricular vendor.

    The link for a list of the control is below...though they use a different "stock" number, it matches the model you provided.

    You`ll need to enter your model number at either of these sites or you can enter in the exact part number if you can pull it from the original control.

    Let me know how you make out. These sites may be useful depending on where you reside, I believe they have brick & mortar depot`s ( "Reliable Parts" does for sure, I use them personally ) but if you don`t mind purchasing such things on-line it should be helpful.

    Good luck.

    Hi Macmarkus,

    Last question before I buy a new part. Are there any other areas within the machine that roaches are likely to have damaged?

    Hello Andy,

    As per your concern I would check the wiring, but as for components that is the only electronic control in your machine and I wouldn`t imagine roaches could do physical damage to the motors, or heater, things like that.

    Visually inspect wires going to everything and chances are pretty good you`ll be fine. Obviously the main thing is the circuits in the control itself which we`ve already discussed.

    Let me know how you fare.

    Good luck again.


    Macmarkus :)

Please follow the bellow suggestions…

Turn off the water supply to the machine, both hot & cold. Remove the cold-water hose from the back of the machine. Put the "machine end" of the hose in a bucket, in a sink, or drain (somewhere for the water to go!). Turn back on the cold water, and see if water really is getting through the hose. Turn the water back off. If you're not getting any water out of the hose, call a plumber.

If the above said suggestion is not the issue then look at the water inlet valve (where the hoses were screwed to the back of the machine), and check for any rust, lint, limescale, or anything else that could be blocking the flow of water. If yes, clean the mesh screens, reattach the hoses, and turn the water back onPlease check the link….

The water inlet can fail, and is a fairly easy part to replace. On the back of your machine, there should be a sticker with the model and serial numbers on it. Write down those numbers, and call Sears / Kenmore (or an appliance parts & repair store) for prices and information about the water inlet valve. They (especially Sears) should also be able to give you a schematic and some instructions on how to remove and replace the water inlet valve, but if you're fairly handy -- it might be just as easy for you to look at how the old one comes out, so you can put the new one in.

Let us know if you have something more to know else accept the suggestion.
Thank You for contacting

Dishwasher stops mid cycle


Do the foll. things:

1)Check if there is water on the bottom pan. Remove the panel down on the backside of the machine and look. If it's water there, wipe it well up with a towel or so. 2)if ur dishwasher doesn't starts then: First, check the usual suspects: Make sure the circuit breaker isn’t tripped and that the wires at dishwasher’s power junction box aren’t burnt. If all that checks out, then go right to the control panel area.
Asko dishwashers have had problems with the wiring in the control panel area burning or melting– very messy. While your problem may not be as dramatic as that, the problem may still be visible. You may find burnt or discolored wire terminals or the spades on the start button switch may be burnt– anything burnt or discolored has to be replaced. You can buy any replacement parts you need right here.

Switch dishwasher on and starts up ok but when it comes to pumping water in it stops and does not do anything else.


Investigate these five areas if your dishwasher won't fill with water:

As water is filling your dishwasher, a float rises along with it. When the float reaches a predetermined level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Check your float assembly. Replace it if you need to.

The water that fills your dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with your dishwasher's filling ability.

Your dishwasher may not be filling with water simply because the water valve's filter screens are dirty and debris-filled. Gain access to your water inlet valve and try cleaning it out. This might be enough to solve the problem. You can learn how to access your water inlet valve in the replace a dishwasher water inlet valve section.

Alternatively, your water inlet valve could be defective altogether. That could be the reason your dishwasher is not filling. Test it for continuity. If it is not functioning as it should, replace it.

Your dishwasher's drain valve is regulated by a drain solenoid. If the solenoid is malfunctioning, it may not allow the drain valve to funtion properly, which in turn could be the reason your dishwasher is not filling with water. Investigate your drain valve and test the solenoid. If the solenoid is faulty, replace it.

No water coming through the pipes

If there's no water entering your dishwasher, check these:
Water-inlet valve The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely replace it. It's usually located behind the lower access panel on the left or right side. It's the device with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two wires attached to it.
Float switch The float switch is a small electrical switch that's located right below the dishwasher "floor." Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

Asko d3120 flashing coffee cup

I had to slide the dishwasher forward (undercounter installation)and tip it forward as far as possible. Water leaks onto floor, but then the internal controller seems to reset and the ASKO now works normally again. What kind of idiot would design a control module that does not incorporate a power-off interlock? FAIL FAIL FAIL - Bad, ASKO, Bad. Go to your room.

Drainage Problems

Turn off the dishwasher by pressing the on/off switch on the top left of the dishwasher. Wait 5 seconds. Press and hold the program button on the right side of the front of the dishwasher. As you are holding the program button, press the on/off switch again. Release both. This should reset the machine

I got this with another dishwasher. On that one it meant the water wasn't feeding into it (tap switched off, kink in inlet tube, etc.)
