Mike for Model Number WDT710PAYM6 My dishwasher runs, etc., but the middle and upper spray arms barely move and/or seem to spray out any water at all. I've had the thing out from under the cabinet and checked everything I can, but no giant hunks of glass or globs of food or anything at all untoward was found except for a very small, garden variety rubber band found in the drain pump chamber ("drain pump," part AP6020066 by Whirlpool) that I assume had more to do with produce than my dishwasher. I was, in fact, rather pleased with myself that the innards were so weirdly pristine! LOL! The motor located toward the back (what your site calls the "motor-pump," part number AP6022491 by Whirlpool) does seem to be a LOT louder than it used to be, but there again -- how do you know if that makes a difference? Thanks
Answer Hello Mike, If there are no clogs and the unit is filling with a sufficient amount of water, the issue will have to be an internal water leak causing a drop in the water pressure produced by the water pump. This could be a missing seal at the center spray arm connection point or even a cracked feed tube assembly. Read More... Answered by AppliancePartsPros.com | Friday, August 23, 2019
