Dishwasher seems to be doing everything except washing

Good Afternoon Stephanie,

I understand the spray arm is not raising all the way in your Frigidaire dishwasher, model# FDB750RCC. I also see that the dishes on the top rack are not getting clean due to this. The spray arms are stationary where they are attached to, other than turning due to water pressure. Please try the following solutions:

• Choose another cycle for longer washing time.
• Check rack loading section for proper loading-avoid nesting items.
• Home water pressure may be too low- should be 20 to 120 pounds per square inch (psi).
• Check incoming water temperature. It should be at least 120 degrees F.
• Select HI-TEMP WASH option.
• Check water hardness. For extremely hard water, it may be necessary to install a water softener.
• Use fresh detergent.
• Check to make sure funnel in top rack is not blocked.
• Make sure items are not blocking the spray arms, preventing them from rotating.


I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

-Best Regards-

Make sure the center loading is not obstructing the water jet to the top shelf. Top shelf is only for glasses and saucers , use Jet-Dry .Pre rinse and clean bottom pan strainer from dirt debris.

Hello,

the greatest possible problem is the tube that connects the upper wash arm to the water supply tube on the back wall of the tub is cracked so water cant get to the upper wash arm. That tube can be seen by pulling out upper rack and looking up at the bottom of rack, its usually grey and has a funnel on the back of it.

I hope this helps,
Gene

There is a pipe/tube that runs up the back of the inside of your dishwasher. This provides water for the top spray arm. The spray arm has a feeder tube that covers the pipe in the back. If for some reason the feeder tube has come dislodged, the water just drips back down into the dishwasher, never touching your upper shelf. My kids used to jam cutting boards and other large items into the lower shelf and in so doing, would dislodge the upper spray arm feeder tube. Just pull out the upper shelf and check to see that the tube is in the correct position. This should solve the problem.

If not, then the spray arm may have debris in it that keeps the water from being forced through the jets. You'll need to flush the arm with the spray attachment on your kitchen sink. I sometimes use tweezers or a toothpick to dislodge bits of peelings, paper, or bone that manage to get into the sprayer arm.
I hope one of these tips helps. If it does,please come back to fixya and rate my answer.

Jeff, When a dishwasher acts like this, the most common problem is a blockage in the sump area, underneath the lower spray arm. Removing any/all filter and covers down there (screws will need to be removed) and inspecting with a flashlight, remove all debris (watch out for broken glass!)  Also, inspect the "impeller" that is turned by the wash motor for damage or being loose while you are down there.  Reassemble and test out.
If problems remain, the next most common problem is a failed wash motor.  It is common over the years for it to weaken as it heads towards total failure.  These motors, when they fail, can not be repaired, rather they must be replaced.
Please post back with what you find, OK?

make sure that there is nothing blocking the racks, no big pots or pans, if thats ok then take out the bottom rack, u will see the sprayer, use something long, a screwdriver should do, u should see a slot in the sprayer at the bottom, stick the driver through it and give it a turn, it will loosen, take it off and make sure it isnt clogged, also, ull see a little cover that looks like a grate, take that off also and make sure it isnt clogged under neath

spin the top rotary arm to make sure it spins freely also take it off to see if its blocked (run it under tap) check all other filters too and when you load dishes make sure they do not obstuct top rotary arm if none of this works then it's time for an engineer im affraid good luck

Clearly a design or manufacturing flaw. I have the same model and the rack is disintegrating after 6 years. I believe it is a manufacturing flaw. Our previous dishwasher rack lasted over 20 years in the same conditions. Same construction, vinyl covered steel. New upper and lower racks cost over 200.00 and there is no guarantee that this won't happen every six years. I recommend a new non-Maytag dishwasher as soon as you can. Meanwhile, limp along with the defective racks.
