Chosen Solution
Dishwasher stops draining at end of cycle. i press ‘cancel’ & it drains completely. Other Issues: foul smell from disposal even immediately after cleaning. same sludgy pipe smell in dishwasher. I have:
- Checked/cleared all hoses running from dishwasher, disposal & air gap.- 2) Checked/cleared filter, chopper assembly, drain hose/pump connection. 3)-Snaked pipe going out from wall. Of Note: there is an Air Gap and High Loop on Drain Hose. And i’ve noticed that the rinse aid level has remained at full for several weeks when usually it consistently drops with each use. My inkling is improper hose pathways, but they look ok to me - or weak drain pump. Any suggestions before i start replacing parts?
Update (05/19/2021) Jayeff, thank you for looking at my post, and for the suggestion. No,i have not tried eliminating the loop, but i will. That’s how it was installed and has been working well for years. I am attaching a photo with more detail, if you wouldn’t mind… let me know if it looks right. Also of note: there is always water in the drain hose all the way to the top of the air gap - even when there is no water in the tub. What does this suggest?
I am so baffled- i don’t know which is the more likely fix: replace control board or drain pump. leaning toward new pump. Update (06/15/2021) Ok guys, there’s a new twist in my dishwasher drain drama - it has further confused me, but i’m hoping it will make sense to you tech experts. Before removing the drain pump, as discussed previously in this thread, I ran it… and chose a different wash setting. Our panel always defaults to Normal Wash + Heated Dry. ..b/c that’s what we always use. I ran it on Light/ China Clean Up - and no Heated Dry & guess what? It went full cycle, wash, rinse and drain.. to the end! No stopping and no water left in the tub. Does this confirm your suspicions of the control board as culprit? p.s., still full water in air gap line… separate issues?
Hi @hilife Standing water in the drain pipe between the air gap and I presume the bottom of the loop at the back of the machine is not good. Maybe a little but not all the way to the top of the pipe. There will be no draining back of the water into the machine as there is a check valve that diverts the dirty wash water to the drain pump but prevents it coming back into the machine itself You said that you checked the drain hose for clogs etc but maybe you need to check the drain pump itself (as best you can) to see if the pump is OK and not clogged (maybe where the smell is coming from?) or perhaps the impeller blades may be broken or slipping reducing the pressure of the flow through the pump. Here’s a link showing the location of the pump. It also has a video on replacing the pump as well which may help. Here’s the tech sheet for the dishwasher which may also help. On the lower half of p.1 on the left side, it describes how to get into the diagnostic mode so that all the functions of the dishwasher can be tested. (Sometimes the tech sheet can be found behind the kick plate (toe plate?) in a plastic sleeve as well) If it is determined that the pump is the problem there are other suppliers online that may suit you better. just search for KUDS02FRSS4 parts to get results.
If pressing cycle makes the unit fully drain, and it doesn’t seem to struggle doing it, I’m thinking its more of controller issue. You didn’t post brand or model so can’t confirm, but does the controller also tell when to add the rinse aid? Because you mentioned that stopped dispensing as well. The hoses look correct. As for the smell, try running an.empty cycle on the dishwasher with a little bleach, and drain it immediately after. Then fill with clean water and drain again. As for the smell in the disposal, what worked for me when I had that issue was filling the sink with hot soapy water, pulling the drain, and letting the sink empty completely while running the disposal the whole time.
Agree, if it drains easily on CANCEL then the pump is working. If the loops have been there for years, leave them. It more sounds like a control issue. Are you sure it is at the final drain cycle when it stops. It may be at the drain cycle prior to the rinse if it is not taking any rinse aid.
