Retains water in the bottom of the unit after it's done. I've removed the prelimanary screen and the secondary and cleaned the third. I poured in about 2 gallons of boiling water into the drain area, in case of grease blockage, and that did nothing but fill the bottom of the unit to the open door.

Remove the panel at the base of unit below door you should find the tech sheet which will tell you how to place unit into diagnostic, on the spray arms make sure the small holes are clean below the lower spray arm is a screen make sure it is clean not covered or cake with calcium build up if it clogged water cannot pass thru to enter the wash pump you can also remove the screws to take the upper halve apart to inspect the wash pump for any obstruction it is possible you could have a bad motor control or both you didn't mention after the unit fills do you hear the wash pump hum or click
I would asume the unit drains properly.if it does then you main need to replace the main wash pump.but if you can remove the screen in the bottom of the unit and look in the for any thing that may cause the impellar wheel to stop clear the obstruction.If the unit does not drain then you will have to do the same thing for the drain pump,you will have to remove the unit from the cabinet in order to get to the drain pump.
If the is standing water you can use a wwet dry shop vac and attch it to the end of the drain hose below the sink and remove all the water that way.
No drainage, or poor drainage issues are usually caused by either a failed drain pump, or the sump area under the sprayer is clogged with debris. The sump is the area at the bottom of the tub where water collects on the initial fill. A wash pump cycles the water throughout the wash cycle, followed by the same water being drained from the unit by means of a drain pump. This area is usually covered by a coarse screen and fine screen to prevent debris from accumulating. But, over time, some debris may still get past the screens and collect in the sump. This usually results in poor cleaning results due to restricted water flow through the spray arms, and poor draining.
I would recommend you remove the lower spray arm and screens and check the sump area for obstructions. If the unit still has standing water inside, use a wet/dry shop vac to drain. Remove the drain line from your sink and pull a vacuum on the end of the dishwasher drain hose. If the water drains freely from the unit, then you probably have a bad drain pump. If the water will not drain, you have a clog somewhere. Check your drain lines and pump for obstructions.
If you have any questions, please post back with a MODEL NUMBER. I hope this helps you.
Remove water out of dish washer to acess the screen to clean it out in the bottom. Once it is clean you may have to remove the drain hose to clean it out.
You may be able to remove water with a shop vac or cup to get water out of washer to check it out.
Food will get in the bottom at screen or past it and lodge in right before going to pump to stop it up.
Have you cleaned out the screen in the bottom of the dish washer. Sometime's food will get in the drain there past screen to stop the drain up. That would be the first place to check.You could use a shop vac to get up excess water to get to drain to clean out inside unit.
If this doesn't help I have included a little information on how to remove dishwasher from cabinet to acess drain line.
If you can't acess the drain line you may have to take dish washer loose and slide out to get to it. To do this remove 2 screws that are connected from tabs's near the top of the door under the cbainet top.
Open door and look up and there should be two metal tabs with screws in them holding the washer in place. Next you will need to shut water off and disconnect the water line which will be located near the left front at bottom once you take the removable panel loose.
Also shut power off to washer and you may have to disconnect the power supply if it isn't enough wire to pull unit out. If you if has enough wire and water line you maybe able to get it out without disconecting them.
On the back side of the pump the drain line is connected to it. You may be able to take it loose from underneath, not much room if it can be taken loose with unit in place .
Anyway I hope that I have included something that maybe of some help to you.
It will be smelly water and if you have access to a shop vac that will help you remove the standing water if not use a bowl or turkey blaster listed below.
Use a small bowl to remove standing water from washer to access screen to remove and check for blockage. Once you have removed all the water that you can with a bowl or cup. You can use a turkey blaster to sucton remaining water from dishwasher.
Then you remove screen and clean out drain and also check drain line for blockage from dishwasher to under sink.
Clean out drain to unclog in bottom of dishwasher and you may have to remove drain line to clean it.
I would check your drain line make sure its clear and you dont have any restrictions. You could also run 4 cups of vinegar through the unit to clean your screens you may have alot of soap scum built up. Also make sure your drain is not backing up. If this is a GE dishwasher you may have a bad piston and nut assembly. The other option would be a bad drain pump. Hope this helps _MJ_
the drain pump is fairly easy to replace. it locks into place beside the sump and motor. push tab in and rotate pump to pull out. you will lose water so have a towel handy. inspect drain hose for restrictions or kinks.
on all dishwasher think of them as a simple gutter system. the water only has one drain. At the bottom, if the pump can't pump out the water, its simply a bad pump or a clogged drain hose. Food particle can clog the "drain screen", use a good quality shop vac, clean 'drain screen', remove drain hose and clean thoroughly. If the hose goes into your drain pipe, remove that and clean that really good with snake it its metal or a strong 1/2 zip tie if its plastic.
