Do what stevet said. I just finished a renovation on a KDS-20. I have a repair manual, which always helps. I took out the selector switch and completely soaked it in WD-40, then blew it out with compressed air and wiped it off with a lint free cloth. Remove the decorative buttons before you start and make a diagram where all the wires go. When you reinstall, push the switch all the way to the left, before you tighten down the screws completely. You may have to adjust the switch cancel lever, if it doesn't push the reset tabs in all the way when you open the door. The door latch lever pushes the switch cancel lever when you open it. The switch cancel lever hangs down and is adjustable up and down to make it push harder or easier on the reset tabs. Clean the decorative buttons and spray a little bit of WD-40 on the back side of them to make them go on easier. Pay close attention when you pull them off, so you'll know exactly how they go back on. On mine it seemed like they were all the way on, but I discovered if I pushed just a little bit more, they popped on a bit farther. I don't know if your model will be like this or not. Also, when you're taking the control panel apart, it's easy to drop the end pieces and break them. Be careful when cleaning the inside panel. You can mess up the decorative back of the plastic and it will make the front look bad. All of this probably won't help with your pump-out problem, but if you figure out what's wrong with the pump you can do this to help the switch work better. If you do this, don't take the switch apart, just soak it a lot with the WD-40 and blow it out really well and wipe it off. Remember, after the KD-20 series, they switched to the reversing motor for pump-out. The ones before were single direction motors. I don't know if that could be a clue to your problem or not. If you figure out what's wrong and the rest of the machine is in pretty good condition, a pump rebuilt might be a good idea, if you think you can tackle it. Check thread #27751. One thing I omitted in that thread number is that there is a rubber "O" ring that goes between the wash and pump-out impeller. The pump rebuild kits don't have spacer shims under the pump-out impeller any more. They just have a rubber and white plastic insert piece that pushes into the bottom of the pump-out impeller. They still have shims between the pump-out impeller and the wash impeller. You have to put them back in the same way they came out or the impellers will drag and squeal. I've never worked on any thing newer than a KD-20, but I don't think they changed much until the 23. Hope that helps.
