Asko D1606 won't fill, and sounds like pump is running

Our unit had leaking connection on outlet side of fill solenoid valve. Any leak will cause water to accumulate in base pan. there is a float switch in base pan as a safety mechanism when water is in pan it causes a styrofoam float to rise and make contact with switch. This tells machine there is a leak creates error code to run pump continuously until water is removed from base. Disconnet electric from unit first. you must pull dishwasher out to get at back panel. Remove lower back panel to get access to mechanicals of unit. Once you remove panel you should see water in pan. If you see water that is most likely same issue we had. soak up excess water or tilt unit to drain water out of pan. once water is gone unit should start normally. If you look underneath while unit starts up - don't touch anything while unit is connected to electricity! You should notice where water is coming from. Our unit leaked at hose connection from outlet side of solenoid fill valve. connector is a plastic cam-lock fitting with a flow sensor integrated into it. there is an o-ring between the two parts. it comes apart with a very small amount of counter-clockwise motion. perhaps only five or ten degrees of indexing and it falls right off. it is a very flimsy connection for the main water line. the o-ring on our unit Was slightly deformed and not seated correctly. could have been from original installers 4 years earlier! Asko needs to re-design this part. I replaced o-ring and unit is working again however I do not trust that this fitting will hold up over time. Very poor design in my opinion. Other design flaw I noticed while looking at mechanicals is circulating pump isolation mount is not in correct location for pump motor. rubber mount is stressed to the point of almost tearing off! No way for me to correct this since location of mount does not match position of motor. We will not replace this unit with another ASKO when it goes.

Sounds like the inlet water valve is not seated properly and is letting water in when it shouldn't .

Just wrote you a massive explanation then closed my window by accident. Lets try again!

From what you say, with water running even when powered off, this is certainly a mechanical failure of the water inlet valve. There will only be a couple of possible causes for this:

1) The valve is being jammed open by an obstruction, possibly grit in the water supply (did you have plumbing work done recently or work on the water supply in the street? This would be a classic cause). If an obstruction is the case then repeatedly starting a fill cycle, draining and satrting the fill again MAY shift the blockage.

2) There is a failure of the valve its self. Essentially it's just a valve with rubber seals operated by a small electro magnet and sometimes the seals fail (often as a result of a poor water supply allowing grit into the rubbers).

If the information at (1) above doesn't help, you may have to replace the valve (Though in examining it when you come to take it out, you may be able to locate and remove an obstruction).

To help you out there is a parts manual for your machine available in PDF here:

http://www.greatplainsapplianceparts.com/order/Parts%20Manuals/Asko/ASKO-Dishwasher/D3112%20(DW20.1)%20SS.pdf

Looks like the diagram on page 2 shows that you need part 135, although it seems to me that the author of the manual has got part 135 (Part No. 8073774 Cord Set) mixed up with part 140 ( Part No. 8073825 Inl. Valve Single 120V Sens.).

I imagine that if you go to the ASKO website and use the contact us option:
http://www.askousa.com/customer-care/contact-us/
They should be able to clear that up for you

Hope this all helps

Hello, welcome to FixYa.

Based on your description and provided the dishwasher is indeed 1) an Asko 1875 and 2) filling with water, draining, heating, but not circulating, It sounds like a busted wash impeller within the main motor/circulation pump, unfortunately.

First though, do you hear a quiet sound of the wash motor starting once the unit has completed filling with water ? And be sure the unit is actually filling with water, this image below indicates the normal water level to look for....





The pump will be super quiet if the wash impeller is broke as I suspect it may be...almost like a fountain, since the Asko are very quiet under normal conditions. You will have to either get right down with your ear to the bottom or run it with the door open by activating the door switch with a screw-driver and look for visual/audible clues.

If so that is a tell tale of no wash action yet the motor runs, hence broken impeller. If you don't hear anything it may be a wire come off the main motor/circulation pump...but not likely.

This unfortunately is common with Asko built dishwasher`s and it is a case of being a victim of their own design.

What happens typically is the ball-bearings from the upper rack holders ( which are plastic, hence fatigues due to heat and fall apart ) come out making their way into the sump, hence breaking the wash impeller from the motor.

Let me know what you find and I'll try and help you move forward from there. If you need direction to remove the circulation motor and pump I can do that, but it is a pretty involved repair and requires pulling the unit from the cabinet...you may opt to call in a pro.

I'll watch for your reply and try to help in any manner I can.

Hi Tony,

I have the same machine (D3350) and almost the same problem.

Mine starts each cycle fine - pumps out - fills - rinses - pumps out tht first load and then does not fill again. If I manually fill with a bottle (about 2 litres) for each subsequent cycle then it washes as well as it ever did.

Seeing it fills once it cannot be the water supply, nor the solenoid that operate the water supply. So, my guess is the control panel.

Like you I would love to simply take advantage of the PC Upgradeable featurewshich seemed so attractive at the time of pruchase.

check to see it the dishwasher has been pushed back ever so slightly. The water coming into dishwashers and exiting are on timers and if the hose is pinched this can affect it. Your dishwasher may appear to be in the same place but just pull it forward and try it again. What has you got to loose except big repair bill or a new machine.

Solved by draining water from bottom pan.

the carbon brushs in the motor need replacing,on the w6021 the fault you get is a clicking sound when you press the start button.
