Of course you can open the door during the cycle to check to see if it's leaving water. When you first hear water draining, time it. About 45 second later you will hear the drain valve snap shut and the timer will advance to the next fill. That moment is the time to open the door and check to see if it is emptying completely. When you close the door, you will have to push the cycle button that you had first chosen to start the machine again.
I suppose the safety pressure valve could be faulty and that it's overfilling. If that IS the case, though, I suspect that it would be overfilling enough such that machine would be leaking. You can also open the machine while it's washing to check. Just lift the handle and wait a few seconds until the water stops if you want to avoid getting wet! As to possible causes for this...while I suppose there COULD be a problem with the drain pump impeller, most likely there is an obstruction somewhere. This could be in the pump, one of the hoses, or perhaps the drain valve itself. I would start my investigations with the easiest things first the hoses, then the drain valve and save any investigation of the pump until last. Here is what the water level is on my KDS-16 for a full fill.

Kenmore71, Thanks for the good advise and the picture of the water level. Any thoughts on how to loosen up that screw if I have to look in the pump? | ||

I read your first post again and I fear that I may be the bearer of bad news. A squealing sound that goes away when water is added is, more often that not, a leaking seal that is allowing water into a bearing. The water quiets down the squealing bearing FOR A WHILE until the the bearing rusts to the point where it seizes.
I've never had the pump apart on a KA dishwasher so I have no ideas to share with you there. Have you downloaded the KD-16 series service manual from Automatic Ephemera? I've posted the link below. It's a small price to pay for a clean scan of the same manual that KA repairman would have had in tow in 1970! CLICK HERE TO GO TO Kenmore71's LINK | ||

KDS-16 Draining problems The most common reasons that these DWs don't drain fully are.
Clogged air-gap on the sink counter-top [ if your DW has one]
A piece if broken glass or other forigen object caught in the drain valve or other blockages in the drain line.
Damaged drain impeller in the pump, this was really very common on 15-20 KA DWs and if the two things above don't turn up the problem you should disassemble the pump and look. The main SS impeller screw will unscrew if you use a good screwdriver, you will not be able to break this screw off with hand force. | ||

Thought I would have a chance during the week to work on this and report back. Looks like it's the weekend again. Didn't want to wait any longer to thank you guys for the help so far. I will report back on my finding. John | ||

Broken Port on The Lower Pump Housing I am going to give a little difference advice on dealing with this problem, { I have been repairing residential KA DWs for nearly 40 years ] And I have seen this part broken at least a hundred times [ this part breaks off easily if you don't rock it loose after the screws are removed ] You can put epoxy or a good waterproof sealant on it if you wish or you can just screw the upper part back in place, it will form a very good seal when the two broken parts are screwed into place, also do not remove the part that is stuck in place unless you find an intact replacement, that part does not need to be removed to rebuild the drain impeller and water seal. | ||

Removing Drain Impeller Bits The picture of your failed drain impeller is what I expected to see when you first described the problem you were having with poor draining performance. Back when these machines were popular we would often do several drain impeller replacements a DAY, the 18-20 KA DWs also had lots of problems with broken drain impellers from foreign objects getting caught in the pumps. KA didn't didn't cure this problem till the introduced the all new new pump design used in the KD 21 and 22 machines.
I would remove the hose and drain valve and check for any bits of stuff stuck in the hose or drain valve, doing this will not likely cause any problems. You may also want to replace this section of hose and the two clamps unless the original is in great shape, automotive heater hose of the correct diameter will work great for the temperature and pressure involved here.
