That model was producedby asko. Which is now owned by sub zero - wolf. Suggest to get parts direct from mfr as it is more cost effective. Hope this further helps

Suggest that you pour a cup of CLR in dishwasher and let stand over night. SHOULD desolve the build up.

Try running it through with just water and no dishes. It should drain then. and if that doesnt work, power it down and restart the dishwasher.

Hi

When the Dishwasher won't fill you'll need to check for the water inlet hose, the water inlet valve and the float switch assembly. When the water fills your dishwasher, a float rises along with it. As the float reaches a certain threshold 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. Sometimes it can happen due to float valve and on other occasions due to float switch. Inspect the water hose coming to the dishwasher for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the float switch assembly should be replaced. Hope this helps... Please post back if you need more information.

Hi,
You made have a leak causing the drain pump to keep running, if you never worked on this unit before I would suggest you call a professional. If you have worked on this before then look for water in drain pan to unit, the reason is water has entered drain pan and caused the float to turn on pump, could be from the drain hose, leak in a hose, or the diverter. all this part are located unit unit in access area (small panel under large door).
Good Luck, I hope this helps... I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249

Hi,

You either have a faulty drain pump motor..Or there is some blockage at the pump to drain hose area....Remove the front bottom kick plate....Set the washer to drain...See if you can hear the pump humming ..If so you will need to remove the hose from the drain pump...Be careful o the amount of water that will come out...Best thing to do is use a shop vac to empty the inside drum...Then use again underneath once you carefully remove the hose. Pump is easily accessed once you take off the bottom panels, so do that and investigate as needed to see what is really wrong. There is no secret to taking off the bottom panels-all screws are clearly visible.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi

The issue is either with a bad chopper assembly or the impeller is bad and should be replaced. You have to take it apart and check it. Hope this helps...please post back for further assistance.

If you live in the USA, and please don't say, your pump didn't fail because of a bad ground @ the outlet. There may have been a loose connection on the outlet but I doubt it was a grounding problem that caused the pump burn out.

But that isn't your question. You complain of no water. Is there a valve "inside' on your commercial machine on the water supply? Is there a screen on the water input that may be clogged? Are you certain the water supply is turned on? Normally, a dish washer would be hard piped (using soft copper line) not a hose. You say it is a hose, however. Please check both ends of the hose - (remove it if possible) and see that it will pass water. And lastly, make sure the solenoid that will be found near the water connection point is still properly wired. If you can, check the voltage at that solenoid when the machine is on a fill cycle. No power at the solenoid, no water can enter.

Just a few thoughts. Hope you get it going ... let me know your progress ... I may have a few more thoughts.

Hello, welcome to FixYa.

Based on your post, it is likely nothing very serious, but the "resolve" requires some more investigation on your part. The lights indicate an overfill has occurred, saying that I suspect it is actually the drain motor you hear operating constantly.

**before proceeding turn the dishwasher power off via the home breaker panel, or unplug it from the wall if that is possible...most are hard wired to the home electrical...safety first**

The first thing to do is remove the toe panel/kick plate and inspect the base for water. If water is present, with the aid of a sponge, towels, or a wet-dry shop vacuum, absorb the water from the base...

**it should be known that if you leave the unit for a few days, the water in the base will evaporate hence appearing as everything is fine again...if a problem/leak does exist it will return.**

If the unit works fine after resetting the power/breaker and soaking up any water present, it can likely be chalked up to a drain back-up or obstruction in the drain hose or pump... (it could mean a faulty drain pump so you'll need to pay close attention the next few times you run it)

...If not, there are a couple of other possibilities that I'd focus on.

**Again insure power to the unit is off**

The first is the float and subsequently, float switch. If you've removed the service panel at the bottom, or toe plate, you need to locate the float and it's switch. It will be located directly behind where your main electrical junction is.

Once you've located the float behind the main connection plate, you should see something like this image below,

i.e.


With the aid of a long screwdriver or if you can reach it, move the float up and down and listen closely for the switch to "click", indicating it is indeed functioning. Restore power again, and see if this resolves the issue, if not try this next...

The pressure switch too can cause the drain/outlet pump to run constantly, the pressure switch is the component which controls the normal fill level and the overfill detection...pre float activation. The float is primarily the last ditch safety to prevent disaster in the event of a overflow, back-flow, or leak underneath the unit to service or call for service to the unit.

It too is located under the machine and is mounted to the sump well assembly as shown, the large arrow indicates the switch while the small is the hose.
i.e.



The issue often can be just the hose going to the switch is clogged with debris such as dirt, detergent buildup etc and will be remedied by blowing it out.

The best way to do this is to remove this hose at the switch in the location indicated above, be very careful as to not break the hose off with the part of the switch inside, they can be delicate.

I typically work it loose with a tiny screw driver gently working it away from the switch. Once removed, pour a small amount of hot water, white vinegar or "CLR" through the sump from within the tub...or you can try blowing it through with "lung power".

The other end of the hose is located at the back of the sump well and is quite vulnerable to blockages over time due to detergents, dirt, and such.

This is the location...do not break this or you will need to replace the entire sump well...no fun.

Large arrow is pointing back to pressure switch, small indicates connection to sump well, sorry for the poor quality...it's hard to get in there with a camera phone, ha ha !

i.e.



Hope this helps move you forward, or even better resolves the issue altogether. Let me know of course, I will help you move further if necessary. Good luck.

You will have to check if the dishwasher is stuck in the drain cycle or wash cycle.

The normal and economy lights flashing means there is flooding in the unit.

Reset the unit by pressing START button for 4 secs. If the flashing does not stop then you have to call the technician. There may be a leakage which is causing the flood switch to activate.

you can use this site to order your broken part http://www.allvikingparts.com/ did you get the basket out? I repair all types of viking here in Rhode Island and this is the site I use to order any viking parts for any machines that I need parts for if you have any further questions messsage me back I await your reply Thanks Rick

On this unit there is not , sorry

if you have sediment in the water then the screen in the fill valve may be plugged.

Hi,

Here is a tip that I wrote about dishwashers and them leaking.Leaking Dishwasherheatman101

This is probably okay, you have clock like motions running the motor electric contacts. There needs to be a delay between some cycles or shorting will occur. The motor on some designs, for example. is reversed to pump out water. to have this work long term, a delay is inherent and not a concern.

Please check the user guide. There may be settings available like sleep timer in TV sets.

Hi,
Here is a tip that will help you...

heatman101

spray's are most likely clogged with food debris,carefully use a small nail or similar object to clean them out.

Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.
