GE Model GSD5500G00BB Dishwasher. Water standing in tub.

Customer Question

GE Model GSD5500G00BB Dishwasher.
Water standing in tub. Appears to be dirty and not pump out. Removed plastic screen in the floor covering a sump. The holes on the bottom were 90% plugged with what looked like powdered soap. After cleaning, i ran a rinse cycle and dirty water- from what was left in the sump after I had hand emptied it- filled the tub. I then ran a short wash cycle and at the end dirty water still in the tub. Where do I go from here?

Any help would be appreciated. Thanks

I beleive your problem is going to be the piston and nut assembly, # XXXXX on this diagram, remove the screen in the very back(plastic) 4 screws holding it and remove the piston and nut by turning it counter clockwise, Part 821081this is what it looks like, its spring loaded and is suppose to close tight in drain cycle to prevent dirty water from returning into the tub. check the rubber part and see if it closes tightly, thanks Bryan

I have taken out the part. I don't know if it closes tightly. How do you tell. It looks worn but it looks like it should close. Does it have to be real smooth on the conical surface. If so it is not.
Thanks

I scraped the rubber cone and most of the irregularities appeared to be soap. Its more smooth after the scraping.

Without knowing how much pressure is put on it while operating, how do we know if it closes tightly enough. The rubber on the bottom edge of the cone looks like it is wearing but the top part where the cone makes the seal looks worn but smooth With the right pressure, It looks like it can close to me but I've never seen the piece before and have no experience.

I just ran it thru the rinse cycle and it still leaves water in the tub. I disconnected the hose where it connects to the disposal and found some gunk but it was not blocked.
What's next?
Regards

Expert:  Bryan replied 7 years ago.
i would take the hose off the disposal and get a bucket ,put the hose in the bucket and try draining it, see how fast thye water comes out, let me know , thanks Bryan
Customer: replied 7 years ago.
Water came out at a good pace and emptied a lot of what was in the tub.
Expert:  Bryan replied 7 years ago.
ok have you changed your garbage dispolsal lately?
Customer: replied 7 years ago.
Changed my garbage disposal lately? Have I put in a new one? No. How else can I change it?
Expert:  Bryan replied 7 years ago.
just wondering because there is a knockout in the drain you have to take out, if this is comming out of the hose full force when you put it in the bucket there must be a clog or restriction in the drain. have you put a large screw driver into the hole in the disposal and clear this.?
Customer: replied 7 years ago.
No, I think I must not have been clear.

I lowered the hose from the disposal below the level of the tub. Then water came out not before. I have not changed the disposal or anything to do with it. Water comes through the hole in the disposal. I know this because I mistakenly dumped some water in the sink while I had the hose off of the disposal and got wet. Dumb, eh?
Expert:  Bryan replied 7 years ago.
yeah I've done that too! anyway can you get the front bottom kick panel off so you can see under the dish washer?
Customer: replied 7 years ago.
Sure! Ok, its off!
Expert:  Bryan replied 7 years ago.
ok when you advance this to drain is the soleniod pull down all the way?
Customer: replied 7 years ago.
I don't have any way to advance the cycle to drain. There are only buttons, no dials on the control panel.
Expert:  Bryan replied 7 years ago.
ok doesnt it say cancel drain on one of the buttons?
Customer: replied 7 years ago.
No, Left to right the buttons are:

Sani Pots & Normal China Light Riinse Heated Lock Delay Start/
Wash Pans Chrystal Wash Only Dry Start Reset
Expert:  Bryan replied 7 years ago.
ok does reset make this go to drain?
Customer: replied 7 years ago.
I don't know. What is the part number on the solenoid that I should be watching if it does drain?
Expert:  Bryan replied 7 years ago.
acually i was looking at the parts in this dish washer and see that this has a drain booster pump, Part 771037I would say take a look at this, this is probably your problem, this will most likey be towards the back of machine though, you may have to take the machine out to get at this. Part 771037this may be bad,
Customer: replied 7 years ago.
ok I have it out and can see the part. Is there any test I should do?
Expert:  Bryan replied 7 years ago.
well does the blades inside feel loose at all. ? was there anything in the hoses or the pump?
Customer: replied 7 years ago.
Took out the part. Lots of water in the exit hose. Disconnected it and drained the tub sump. can't tell about the blades. Can only see them through the entrance hole.

What is next??
Expert:  Bryan replied 7 years ago.
well there isnt much more on this machine, try taking the drain hose an blow through it see if its clear, if it is, you probably have a weak drain pump. this should be pushing the water out fast, not much else left. Bryan
Customer: replied 7 years ago.
What about the box the exit from the pump goes into before it goes up to the disposal. Is there anything in there to plug up?
Customer: replied 7 years ago.
Also, If I pour water in the hole that drains the sump flows right thru and out the exit hose. Is that normal?
Customer: replied 7 years ago.
where is the most reasonable place to by the replacement part? Do you have a part number for it?
Expert:  Bryan replied 7 years ago.
thats where the piston and nut is correct? you have to check every possibility all the hoses and anything else going out, as far as the water draining yes I believe thats normal but the drain pump is what pushes the water up to the disposal,
