Garbage Disposal backing up in dishwasher

I own a Frigidaire dishwasher model #FDB1250RES. I stopped using it because it wasn't getting my dishes clean. There was a soap film all over my dishes, so I've been hand washing dishes. I turned on my garbage disposal while I was cleaning up after dinner and heard dripping. I looked down and noticed water dripping out of my dishwasher. I opened it up and saw the bottom filled with water. My husband cleaned out the dishwasher and filter and made sure all the connections were secure. We ran the dishwasher again and all of the water drained, but there was still some residue at the bottom. Can you please tell me what could be the problem? Thank you!

Re: Garbage Disposal backing up in dishwasher

Most dishwasher have a check valve at the pump to prevent water from backing into the dishwasher. If the pump is electric there is a rubber flat that may be gone or not working properly. If that is the case you need to replace the pump. If the pump is part of the motor assembly then the pump and motor will need to be replaced. One other thing to make sure of is that you have the drain hose looped to the top od the dishwasher and then to the disposal conection. Its called a drain loop and all dishwashers should have it. Good Luck

Re: Garbage Disposal backing up in dishwasher

The first thing you need to do is check how the dishwasher drain hose is routed. Before it connects to the garbage disposal it should go up higher than the bottom of the sink. Since water always runs down hill, it can not get into the dishwasher drain line if the drain line is higher than the water level in the sink.

SOURCE: How to knock out garbage disposal plug

Turn off the power source to the garbage disposal. Take the drain hose from the dishwasher off the connector going to the disposal (if connected). Insert a flat blade screwdriver in the drain hose fitting and tap a few times with a hammer. The plastic plug will pop off inside the garbage disposal. Reach inside from the top of the disposal to retrieve the plastic plug. Sometimes you have to use a little force to tap the plug out. Hope this helps you.

SOURCE: garbage disposal (water won't drain out of sink standing water)

There should be an overload button somewhere on the bottom of the disposal motor. This is to prevent the motor from trying to run if the chopping blades are jammed, otherwise the motor would burn up.

First, try to move the blades with something like a broom handle. Using a flashlight you should be able to see the blades. there's probably three of them. try to make sure each one can move even a little bit.

Next, with the disposal switch in the off position, find the overload button and push it in, Then turn on the disposal switch and see if it runs. If the overload button trips off again, repeat the above steps until the blades can turn.

Let me know how this goes. Loringh

There is food and grit stuck to my glasses. Where is this coming from? I am rinsing all the dishes before I put them in , so it must be in the dishwasher somewhere,

We used to have this problem with a Kenmore that had a built-in "garbage disposal"--it was a little blade that ground up larger food particles. Occasionally a cherry or olive pit would get inside and dull, chip or break the blade, and the symptom was food particles on the dishes. The solution was to replace the grinder.

My dishwasher is not draining completely. There seems to be more water left than last time I used it. Also, I tried to used the cancel/drain feature, with no success. Please give me some suggestions!

Hi and welcome to FixYa, I am Kelly

The drainage problems are caused by particulate in the drain.

There are 3 areas that cause restrictions with larger food particulate
1. The Air-Gap (if equipped) but the most common blockage point,
2. The sink connection. This is usually a garbage disposal connection. If the user is not properly rinsing long enough while the garbage disposal is in use the garbage disposal / dishwasher connection port is blocked with garbage disposal debris.
3. The bottom of the dishwasher sump area under the lower wash arm. If this area is blocked the user will complain of dirty dishes post cycle, It also causes drainage problems, If the user says dishes are not getting clean and it is not draining properly this will be the LAST area to check. Do 1 and 2 first.

I have had multiple call backs on some units... I have learned to call a brief moment before stopping by and inspect the DIRTY dishes in the dishwasher, the sump, air-gap and sink connection. Most of the time I find that the user is placing dishes with large food particulate in the dishwasher or... they are not letting the water run long enough when using the garbage disposal so the garbage disposal port clogs. These are the same folks that have things like pump impellers and pump housings that get broken due to their daily routine habits.

You wil have to clean all of the drain connections for the dishwasher pump outlet all the way to the sink connection. The Air-Gap is the most common area for blockages so pull off the cover.. unscrew the inner top nut NOTING the installed position BEFORE removal and clean out the Air-Gap (if you have one) Otherwise remove the drain hose at each connection and remove the debris. It is OK ot reconnect each connection after your done cleaning. This will solve about 85% of dishwasher drain problems. The last 15% the lower wash arm and support has to be removed to inspect for pump impeller damage or motor pump housing damage.

FYI the 2nd most common reason for drain problems is the actual sink port connection being clogged. Just clean the drain hose connection ports and the air-gap.

I think once you get all of your drain connections cleaned that your dishwasher will operate normally.

Thanks for choosing FixYa,

My whirlpool motor does not sound like it kicks on when started. The dishes are not getting cleaned...and water remains in the bottom. When I hit drain, it will drain. I also recently noticed that I am...

Yes it's most likely related. Your dishwasher dumps all the debris it washes off the dishes into the garbage disposal. I'm not a dishwasher distributor so I can't tell by the model number just what dishwasher you have.
Most people dump little thing in the disposal through out the day with out thinking about it or running the disposal, try running the disposal while your running the water to warm it up.
If your dishwasher has a built in garbage disposal, then from what you've described I would say something either a small metal utensil or a piece of glass has gotten down into the dishwasher's disposal and damaged the blade.
If your dishwasher doesn't have a disposal then it's most likely gotten into the pump impellor and broken off some off the teeth.
Another thing I've run into is that the lines inside the dishwasher get holes worn into them, either from the hot water going through them or the spray, I don't know which is the cause. Pull the trays out turn the top one over and check the line for damage. While the trays are out check the other lines and the pump for visible signs of damage.

Plastic hose disconnect Frigidaire dishwasher - sink side

Most dishwashers connect to the garbage disposal and just have that barbed connection that it clamps onto with a hose clamp, unless that actual connector itself broke off (which wouldn't be pressure related, that would mean someone hit something against it breakin it) You should be able to just use a screwedriver and tighten the hose with the clamp back onto the garbage disposal.

If the plastic connector did break off then you will have to buy a new garbage disposal and replace the whole thing. Which is just a little heavy and time consuming but not all that difficult to do.

Or if it did break off, and your handy with glue, then you could try using a waterproof glue to glue it back on?

Also just a warning, if you try to use the sink, make sure you have a bucket underneath the garbage disposal as water will then leak out the hole where the dishwasher drainage tube was connected until you get it fixed.

Once my dishwasher completed the cycle there is no water but after two or three days the bottom of the dishwasher fills with the dirty water. what could be the reason? I have garbage disposal and one pipe...

You must have your dishwasher connected directly to the garbage disposal and not through an air gap. What is happening is when you disposal fills with water it is siphoning through the drain hose back to the dishwasher. If you sink has a spare hole on the deck install air gap and run dishwasher drain through air gap first. Otherwise make sure you run Garbage disposal often so that water does not get slowed and build up inside.
