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.

Gentlemen,
My repair got delayed again due to working out some health problems that my parents are facing,sorry this has been so drawn out.
You have both been very generous but if I may I have a few last questions before I start.
I recieved my impeller and I notice that there are two cone shaped washers in the bag. Do I install both one on top the the other or just one? I would like to keep one so if I have to get back into the pump (to replace the lower wash pump housing) I have a new washer available or doesn't that matter if the cone washer is flattened?
Also related to the spacers, should I put them back in the same order they came out or mix them up for more even ware?
I am most worried about the spacer on the bottom under the impeller. Should I try to find a new one of those? I don't know if that bares any friction or not. It is not clean like three of the four on the top. The dirty one on top is the one that made contact with the seal.

Does the o-ring seal on top of the impeller need any special seating by itself or just wet it and let it seat by the preasure of the spacers?

Also I think I may have found a lower wash pump housing. I plan to get it but I am worried about damaging the drain housing if I take a chunk out of it while wiggling the broken piece out or from the preasure of installing the new one. I believe that that piece has been broken for some time so my head tells me to leave well enough alone for now and just keep the new one in reserve and put the lower pump housing back together as was suggested and see how that goes. What does your experience tell you.
As always the advise is very appreciated!

Thanks,
John
