We found excessive standing water in the bottom, very dirty, and the water level is close to over spilling the unit onto the floor. Garbage disposer is working fine. I pulled the dishwasher drain hose connection at the garbage disposer and it is open. Now I'm wondering if there is access to the drain from the unit's inside bottom where I could run a cleaning rod? Is drain cleaner ever used to attempt to unclogg, or is this too dangerous? I looked on the parts diagram and it appears that two pumps exist that are coupled with a 90 degree fitting. I would appreciate ideas as to easy steps to take, followed by hard steps if needed. Thanks a million for any help.

Can you get the washer to go into a drain cycle
If you can does it drain at all, look and listen for symptoms

Looks like you have 2 filters in the unit
Part 508 in the sump and Part 451 for the main pump
I would check these first before worrying about a drain hose clog

What is happening here is the water from the sink is draining in the dishwasher. Look where the drain hose from the dishwasher connects to the disposal. If the hose goes stright down to the dishwasher, that is your problem. When the hose comes out of the disposal to the dishwasher, it should go up first about 9 to 12' higher then the disposal. Pull on the hose, you should have enough, and either tape it to the drain line, or one of the two water lines, or get a plastc strap, and tighted it around on e of the water lines, and you got it. Good Luck Tom

Dear Tom, you hit the bulls eye.
We can run the rinse only cycle and it drained completely, and yes, the drain line does not connect through an air gap because we have a rinsing spray in the location instead (I'm not brave enough to consider drilling another hole in the porceline sink top to place an air gap).

And somehow you knew that the drain line lacks the upper loop above the sink bottom elevation (how did you know?). The only catch is that we have no slack in the the drainline so I'll be splicing in an extension, with hopes it does not catch stuff at the splice and create an obstruction. We are going to start using monthly DW treatments of the descale/delime products just to make sure. Thanks a million for the professional diagnosis! We'll check back if something else arises, and if you any further advice, regards and Happy Holidays.

Can anyone tell me how the washer arm can be removed to allow access to the drain inside this DW? thanks a million. There is a drain next to the washer arm shaft that needs to be accessed.
