Garbage Disposal backing up in dishwasher

Good Afternoon Dogman85,

I understand you want to know how to remove the drain plug from your garbage disposal, regarding your Frigidaire dishwasher, model# PLD2850. I suggest contacting the manufacturer of the garbage disposal. They will be able to better assist in removing the drain plug from your garbage disposal. Hope this is helpful.

Hi - Is the unit making a grinding noise? If so, contact a professional because you may possibly have a defective drain motor/pump.

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.

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,

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.

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.

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.

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.

remve the drain line connected to the garbage disposal take a flat blade screwdriver insert it into the garbage disposal and hit the end of the screwdriver , the plug will pop out
to verify after hitting it stick the screwdriver back in if it has not removed the plug do it again

thats sure can be the problem, especially since you had 2 machines with the same problem??? whats the chances of that.?? check your installation of drain hose. correctly done the hose MUST wrap up and back down the side of d/w created what is called HIGH LOOP(prevents siplhoning of water out and would help with debris flowing back through. make sure your cleanig the disposer frequently sounds like your backing up into d/w for sure
