Please tell me how to disassemble the pump to see if debris is fowling the little fan. Have been through the drain system up to and past the pump. Even took the pump out but didn't see any obvious obstructions. The noise began abruptly and is definitely emanating from the pump and appears to be related to that little fan. Don't know if the fan is supposed to spin freely or catch slightly as if attached to a spring (which is how mine moves.) Also, I wonder is this is a warning sign that the pump may be short lived. Other that the noise from the pump, the machine works fine. But obviously the noise is significant enough to make me break in and check it out.
Okay, the followng link explains how to check the drain pump:

If you've already removed the pump once, then you are already ahead of the game. All you should have to do is remove the clean out trap and check the reservior. You can separate the motor from the pump by removing the screws that hold it in place from the pump housing. These pumps can make some noise. They will cavitate sometimes when the water has been pushed through the system and they begin to pump air. However, if the pump is exhibiting louder than usual noises, it may be time to replace it. Replacement pumps can be ordered on oine at searspartsdirect.com or replairclinic.com. Compare the two sites for the best price. I hope this answers your questions. let me know if you need further assistance.
Yes, the clean out reservoir is the molded plastic portion of the pump. If you've already cleaned it out, then you don't need to repeat that step. As far as placement of the drain hose, the following link gives some simple advice on basic washer installation:

Most importantly, make sure your drain standpipe is the correct diameter, and that you have not created a siphoning condition. This occurs when there is not a proper air gap for the drain line. This can happen when the standpipe diameter is too small, if you've sealed the top of the standpipe, or if you have the drain hose shoved down in the standpipe too far. Also make sure the height of the drain standpipe does not exceed 72 inches, or you may experience drainage problems.
To answer your next question, yes, it is normal for the drain pump to cavitate like it does. These pumps are particularly noisy at times. As long as the pump is functioning properly, you probably don't have anything to worry about but the noise. If the noise gets progressively louder, you may consider replacing the pump. Searspartsdirect.com carries them for about $70. I hope this helps you.

Are the clean out trap and reservoir the white molded plastic part of the pump assembly? If not where are they and how do I remove them. If so, how do I remove them? In-situ, I have cleaned the white part of the pump assembly and vacumed the inlet and outlet hoses. You are right re cavitation noise. I recognized the sound as cavitation as soon as you mentioned it. Is it OK to use my washer for now? Also, what is the best configuration for the drainage hose? It seems like the machine will drain best if the hose is not allowed to sag below the level of the drainage end and the drainage end inserted in the drainage pipe below the level of the outlet on the washer.???
Thank you. All is well. I took the pump motor out of the black housing and fussed with the 'little fan' then put all together again and gave it a try...there was a little cavitation at first but it cleared up and is running quiet as ever. I think there was a couple of things occurring...initially debris in the pump assembly, followed by me messing with drain line. There must have been sand or something small in the 'little fan' because it was after fussing with it that the cavitation went away. I can see how a cavitation could develop if the 'little propellar' was not functioning properly. Thank you again. Wish I could have found someone like you when I had to overhaul my dishwasher...learning to read the electrical circuit chart flattened my learning curve significantly.
