I have a Hotpoint HDA3600 dishwasher, installed new less than two years ago, which has stopped draining.
I believe that I have followed all of the steps - checked that the drain hose is clear, watched the solenoid action, cleaned the basket - and everything looks right, but is still won’t drain.
Help?
I am assuming that the pump does run during drain and that the wash cycle runs normally.

Remove the drain line from the house plumbing, pull it back through the cabinets and then drain it into a pot/bowl, gravity should empty out most of the water. If not you have a plug in the drain system.
Did you check it all the way back to the sump?
Remove it and it’s fitting to the sump and check it.
Have you checked the house drain/ dishwasher hook up fitting.
One way to be sure this is not the problem is to undo the drain hose at the house plumbing and try a drain cycle into a pail. Be sure to hold the hose securely in the pail while doing this, also put a towel over the pail to stop the water from splashing all over, unless of coarse you want a shower.

I am assuming the solenoid plunger is pulled down and stays down while it tries to drain.
Is the water still being directed up to the wash arms?
If yes it could be that the flapper valve in the pump assembly has come loose from the actuation arm.

I am assuming you mean the sump in the bottom center of the unit.
I would empty the unit of water so you can properly check the drain components. You should be able either undo the drain hose and empty it into a pot/bowl or siphon out most of the water. A turkey baster comes in handy to get the last bit of water out of the sump.
Hi, Denman - thanks for the reply.
I actually took the machine out of the wall and disassembled it yesterday to troubleshoot the problem. The drainage is unblocked all the way from the box to the sink
What I noticed is that the dishwasher drains much better - higher flow rate and more water volume - the closer the drain hose end is to the floor.
Does this indicate a bad pump? The unit is pretty new, but maybe…
The motor seems to be rotating at a good clip, but might that be the problem?
Anyway, it’s obvious that inadequate pressure is being generated by the drain system.
Any more help?
Here are your parts
Replacement parts for HDA3600 models | AppliancePartsPros.com
Just to double check. I went through the parts list and it does not look like this unit has a Piston & Nut assembly but wanted to double check since I could not find a parts breakdown.
Below is a link to a unit that has this Item 564 in Section 2. This is often a cause of poor draining.

If you click on the picture of the pump on the first page of the parts a new page will open with more views. If you look at the down the throat picture you will see that there is a black seal in the center of the flapper valve. Check to ensure this is there.

I think it pretty well has to be a pump problem as you have checked everything else. I would pull the pump and check it. Perhaps the impeller is slipping on the motor shaft or something similar.
Denman,
Thanks again for your help and thoroughness.
Partsdirect also happens to have the parts diagrams for this dishwasher.
(This is one thing that I really like about Sears!)
No, this washer does not have a piston and nut. It uses a plastic ball called a “Ball filter” (451 on the diagram) to perform that function. Yes, it’s really a plastic ball. If I was a little less mechanical, I would have thrown it away!
I notice that the flapper valve in the picture has a black rubber stem sticking out of the middle of it - kind of like a golf tee? Is that the seal you are talking about? If so, it is definitely missing from the flapper in my pump. Is that the smoking gun?
(Also, my coupler - part 450 - is destroyed. I plan to replace that, but I don’t think that will cause a draining problem - will it?)
Thanks again for your help. Your advice on the rubber stem would be most helpful!

Yes, I think it is. With it missing water will be pumped back through the machine rather than out the drain.

Cannot say for sure on this but anything in the water flow path that is messed up will contribute to your problem.
FYI: I am off to the lake for a few days so will be unavailable. Sometimes when this forum gets busy none of the regulars here have time to look at a post if they see another regular is answering so if you still need help and do not get a timely response, you may want to start a new post with a link back to this one.
Okay, Denman. Thanks for your help. Looks like I will be replacing the pump in this unit
Thanks again!

The ball is VERY important to the drain function on your machine. It has to seal the bottom of the filter shaft to prevent the water from recirculating back through the filter.
I have a similar problem. The solenoid clicks down defintely, but there is no action, only a low hum sound. Does that mean the motor is bad, or what? Thanks, Ed
It could be the motor but may also be something jammed in the impeller/chopper.

I was cleaning my dishwasher yesterday and ran it with the covers off - I found the ball, but, I don’t know where it goes. Can someone tell me exactly where the ball goes? It’s not draining and I knew it has to do with the ball and where to put it.
Thank you,
As far as I know Hotpoint (GE) does not use a ball in their units.
Are you sure it is the same model as the original post.
Looking at the parts breakdown for these units I also cannot find a ball.
