Question about Frigidaire 24 in. FDB740RC Energy Star® Built-in Dishwasher

1 Answer

Frigidaire Dishwasher FDB740RC. Not cleaning dishes well. Just in the past couple weeks. When the dishwasher fills with water, how full should it get. When mine fills, it definitely doesn't go up to the element, and just barely makes it to the float switch (not enough to trigger it), makes it to just below the base of it, doesn't come up the side of it at all. Is this normal, or should there be more water. The Water valve has been replaced already.

Replaced the heating element in my Frigidaire dishwasher and still don't have hot water or dry dishes at the end of the wash cycle.


Hello Bette Good, thanks for your inquiry!

I see that you have replaced the heating element inside of your Frigidaire dishwasher but the dishes are not drying and the water is not hot. You may want to check the water temperature going into the dishwasher and that can be tested by using the sink closest to the dishwasher. The water temperature needs to be 120 degrees, the hotter the water the hotter the dishes will become to assist with drying.

Also check to assure that the rinse aid has been filled that will help with the drying of the dishes. I hope this information has been helpful. -Matt

Dishes not cleaning after full cycle running


Your screens are plugged with food residue in the bottom of the unit. clean it out. You can use 1 gallon of white vinegar for your wash after you clean the screens. Start your washer to fill with water but after the water starts, open your door and pore all of the gallon in the unit. Let it now run for 4 minutes and stop it by opening the door. Leave the door slightly open for 1 hour. close the door and let the cycle continue for 4 more minutes. open the door and repeat it a couple of more times. Let it sit all night with the vinegar in it and in the morning - close the door and let the cycle continue to the end. This should help soften and clean out the food particles in the unit. You can repeat the process and get a better cleaning then too. All the scale should be off your dishes now.

Water did not drain from the bottom


Hello Cheryl, There are a couple of possibilities. When the dishwasher drains the dirty water it is a time based function. This leads me to believe it is a blockage or partial blockage in the drain hose.
Here is an example. (If your dishwasher drains into your garbage disposal) washing dishes you put scraps into the disposal and forget to turn it on after you are done. The disposal is filled with scraps this restricts the flow of dirty waterfrom the dishwasher. If the flow is restricted less water is being drained per second from the dishwasher. This is why the dishes still looked clean and there was still water in the bottom of the dishwasher.
(if your dishwasher drains into a drain pipe) there is blockage or partial blockagein the dishwasher drain hose. if the sink drains slowly the blockage is in the main line
Hope this helps

Dishwasher fills goes through some motions drains but nothing ing clean


Hi

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.

If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes.

Hope this helps...

Our dishwasher is retaining water in the base and not cleaning our dishes fully what is the problem?

Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete.

Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. Check the drain hose for any visible clogging, remove if present. If no visible lint is present then remove then turn off the dishwasher and remove the drain hose and check for any visible clogging. If still not visible then the drain filter or drain pump is clogged and you'll need to clean the drain filter and drain pump.

Not washing well


Hi

First of all please check the Water temperature by using a thermometer inside the dishwasher to measure the water temp. It should be as close to 125 degree F to 140 degree F as possible. Now try using the temperature boost feature if your dishwasher is equipped with this cycle feature and check if this will help your wash ability issues.

Now check the Powder soap by making sure that you store your soap in a dry environment and it is not stale and clumping together. Possibly try a different detergent like a liquid or gel. Also, make sure the dishes are loaded properly, or dishwasher is not overloaded.

To check the proper filling dishwasher will fill with water up to and around the heating element. If water is more below the heating element, you may have low water pressure or a problem with the fill valve. Try & listen if it sounds like it is spraying the water around with enough pressure.
For low water pressure, try to clean the screen at the entrance of the fill valve, sometimes the fill valve can fail and not allow the proper water into the dishwasher and may need to be replaced. And, check the spray arm and pump cover for splits or leaks

Low water fills are a very common trouble maker with today's dishwasher.

Please do accept this solution and revert for further assistance.

Thanks

Dishwasher


I have seen this problem before on a couple of dishwashers.

How are the dishes doing? Are they coming out clean, or do some of them "fail".

If you rinse the dishes before putting them in the dishwasher, it may be hard to detect "failure" to clean. Try not rinsing the dishes once and run them through a cycle. My guess is that the "failure" rate will be high.

The problem I have seen is that the dishwasher water input filter is either clogged or the water-full sensor is "telling" the unit that there is enough water in before it actually fills properly.

So, some water can get in, but not enough to properly wash the dishes and dissolve the soap.

On the appliance repair sites they have parts breakdown details and what you are looking for is an input valve assembly -- the point just after the water line connects to the dishwasher.

Now the valve may be OK, but the feedback system could be bad.

(On a Bosch dishwasher the valve IS the feedback system and the filter.)

Any filtering or "water full" signal will feed back to that valve.

If you get inside that front lower panel, be sure to turn the electricity off first 'cause if you get crosswise in that area you could end up with a 'shocking' experience!

good luck

Dishwasher not washing


By chance have you cleaned the spray arm out lately? There could be something blogging the water from getting into the arm. In most dishwashers, the arm only spins because water pressure makes it spin.
