Does not drain the water at the end of cycle

My dishwasher seems to function normally. The dishes seem clean, but the water from the last cycle remains in after it has stopped. The water is clear. I have read the manual and reset the system several times. When I press the cancel button to flush out the remaining water in the morning, you can hear the water being pumped out, and it sounds like the pump is working well.

I repair and resell used dishwashers as a retirement hobby. After having examined many dishwashers that were replaced because they wouldn't drain, the largest percentage of them were simply because of a clogged drain hose or pump strainer. Too many people seem to think that the dishwasher is first cousin to a garbage disposal. It is not. Even if the instructions state that you do not need to pre-rinse dishes, you should pre-rinse them anyway. The macerators in the dishwashers(the thing that grinds up the food particles, slightly similar to the one in a disposal) are designed to grind up small, soft bits of food, not leftover steak scraps, popsicle sticks, wire bag twist ties (or even plastic ones), paper and plastic jar lables, etc. Yes, I have found all this and more in the pumps). This stuff will clog or possibly destroy the pump/macerator assembly, resulting in a costly repair or replacement of the dishwasher. Sometimes, if enough garbage makes it past the pump and is drained, it begins to collect in the drain hose, and will slowly build up over time to the point where, lo and behold, it will no longer drain. easy fix for that is to first remove the drain hose end from the nipple it's connected to on the sink or disposal, put the end in a bucket, then fill and drain the dishwasher to see if a garbage clog will simply blow out. If that doesn't work, but you see a small dribble of water, you may have to pull the dishwasher out and remove the hose from it to clean it out. Don't forget that there's still water in the unit, so put a drain pan under it before removing the hose, or even better, if you have the unit completely out of it's hole, just tilt it onto it's back before pulling the hose. do not tilt it onto it's side or front, or you'll have the water running out, or into the door cavity, possibly doing damage to the controls.

"Check to see all of your filters are clear. There are float switches or sensors under the water that can get stuck down when they are dirty. After you reset the unit and the water has pumped out, go in with a screwdriver and remove all the covers and screens. Clean everything. If you have sensors or floats, clean them out too.

Be sure to remove all covers as fine particles can make it through some of the micron filters and clog pumps.

Let us know,

"I just installed a new garbage disposal because the last one developed a leak in the plastic casing.

Garbage disposal worked great, but my dishwasher filled up with water. I realized that I forgot to remove the stopper plug from the disposal! They make them with a plug in case you're not hooking up a dishwasher.

So if you just installed a new disposal and now your dishwasher is filling up with water, check to see if there's a plastic plug blocking your drain."

"I had this problem once with my LG dishwasher and ended up replacing the sump assembly and few other parts, cleaned all components an pipes, nothing helped. But then I realized that I haven't checked the wires inside the door. Sure enough a couple of wires got glued to the door insulation due to heat and were torn when the door was opening/closing. One was a ground wire and the other was a white wire running all the way up to control box. Once I fixed the wires all started working properly.

I tend to agree with Mike B, if the water is clean at the end of a cycle and it is draining just fine at the beginning of the next cycle, the problem is likely not with filters or pump or hose configuration. It very well could be the timer, but it also could be the wire that runs the timer, or it could be some other control I am not aware of. But I would also agree with Gil in that it never hurts to run basic troubleshooting before rushing to the store like I did. At the end though we should be grateful for people like Mike B for offering worthwhile opinions that May or may not help and we should decide for ourselves on whether or not to accept the advice instead of making nuisance comments like the one above.
