Q:

How do i remove the lower spray arm of my Maytag Dishwasher model MDC4100AWX?

A:

If the spray arms do not rotate , the dishes are not getting cleaned. Getting this fixed before more water and energy is wasted is important. I did locate two similar questions with information that may help while you wait for the expert to review this model and respond. I attached the links below.

There should be a nut holding the spray arm. I believe the following video will show how to do this: Removing Maytag Dishwasher Lower Spray Arm . The vinegar soak should help but I have seem mineral build up so bad the parts had to be replaced. The video is of a similar model but it should help.

Thanks Barbara. One of those responses helped me figure out how to take apart the lower spray arm. I did that and cleaned up the rinse arm assembly, pump filter and filter plate. There was a lot of lime deposits, especially clogging up the vent holes on the rinse arm assembly, item 7 here: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=47146&diagram_id=28469558#d28469558 The water sprays more forcefully now but the rinse arm assembly is still sticking when it turns. Seems to get caught slightly on the pump housing. Is the rinse arm just old and or is there something else worn causing this? Appreciate any ideas.

Thanks Fred. While I was responding to Barbara I was running it once again with some "salts" I had recommended to me for cleaning it and now the lower spray arm is turning nicely. We'll see if it stays fixed. Which parts would you recommend I replace if it starts sticking again?
