When I was empty the dishwasher. I noticed the rack be getting caught on something. I looked at the bottom of the dishwasher and noticed a substantial spoon had fall down there. I reach down and grabbed it, but later I noticed some other things that seem to be part of the dishwasher. One be what looked like a white plastic holder of some sort... it might hold been a cup holder except the circle be too small to hold any regular sized cups. The other thing be about a one foot piece of white rubber tubing. It be oval shaped and I looked around for places it might obviously fit contained by, but I couldn't find anything. Anyone know where these things are? I don't enjoy access to the owners manual.
Why is my wood buring stove broken correctly?
Answers:    Go to the Kenmore pattern site. to find out if they have an on procession book for the dishwasher.
have your mod.# and serial number handy because it will be asked for. I bought a washer at sear and the manual be missing so I ordered one on line.
