20 Most Recent Viking 24 in. Professional Series VUD141 (Ultra-Premium) Built-in Dishwasher - Page 2 Questions & Answers

Hello, welcome to FixYa.
Based on your post I understand you have a Viking VUD141 dishwasher, correct ? I also interpret your post as you are trying to locate the float, correct so far ? (there is no "valve" present for the float)
As you may or may not know these are built by Asko (AM appliance group)...that being said, the float is located under the tub behind the toe plate.

**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. 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 (if present) 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)


Your Viking will be slightly different, but likely only cosmetics. Once you've located the float behind the main connection plate, you should see something like this image below, i.e.



**Top arrow is the switch identifier, the second is the actual "float" ** 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.
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. the first is the "pressure switch. It controls fill as well as "over-fill" scenarios.

That's the extent of accessing the float assembly. 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 probably have a leak, in the pump housing area below the unit, which is causing the drain pump to run continuously.

you may have a defective pressure switch, this is located on the back of the well, access from the rear of the unit. It black with an orange sticker, from the rear it is slightly to the right of the well, but not as far round as the drain pump.

If the water fills fine and completely, then it means that the circulation pump is bad however, as you have already checked the pump and that is working then test the float switch located inside the bottom front of the unit. Please get back to me if you have any other questions.

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.

If you have hard water, glasses can look spotted and cloudy even after cleaning. Sometimes changing the dishwasher detergent can help. The easiest solution to clearing up glasses that start to look cloudy is toadd some vinegar to the bottom of the dishwasher before you start a cycle. Simply add 1 cup of white vinegar and it will clear up your glasses very well.
You should see marked improvement after the first time you do this. If they are not crystal clear then simply repeat the process until all of the cloudiness is gone. In fact I recommend to using a little vinegar in each cycle to maintain the clarity of the glass.
Note: you can pre-test this by rubbing some vinegar on an individual glass with a cloth. If you cannot remove the cloudiness by soaking it and rubbing vinegar on it then it is possible that the glass is etched due to harsh or cheap dishwasher detergent and vinegar will not solve the problem.

Hi,

I have an older dishwasher also and recently my wife also complained about it not cleaning right... so me being the man I am tried in vain to clean the things... Bought new spray arms online and installed them in minutes...now the thing works like new... However I have also found that if the heating element goes bad then that also can mess things up bad... So I would buy new spray arms, and also check out the heating element to make sure it is working... Here is a tip that will help you with the online buying...

Your pump is worn out. Time to get it to a repair man or get the manual out and if you feel handy be ready for some major expense and time.

are you sure you have a VUD model? Sounds more like a VDB...

defective controller most likely due to a defective diverter valve.

any appliance store/shop can sell a power cord for your unit. the water hooks up front but you'll need an original water supply line due to the shape and fitting.

make sure the drain line is clear including air gap also filters and spray arms! Get Lemi-Shine and follow the directions on the product on how to clean and maintain your dishwasher with it.

remove kick plate, bottom access panel, door panel and door latch (careful with the wiring) and than remove the 6 screws and 2 brackets holding soap dish.

sounds like a bad temperature sensor/thermistor or timer.

Is there a chance the plumber turned off the inlet water connection under the kitchen sink when clearing the drain?
