Kevin for Model Number gu2275xtvy0 I'm trying to remove the lower arm to access the filter area since the top rack is not getting clean and already have checked the top sprayer and mid arm with no blockage found in either. The mid arm turns very slowly and the top doesn't turn at all. I have tried to hold the top nut of the hub and turned the lower arm in both directions, but does not come apart.
Answer Hi Kevin. Is your water manifold that delivers the water supply to each spray arm intact to the rear wall correctly? Is the separate manifold probes going into the manifold holes? Also look at the not - selected hole and make sure that whole is shut wit the flap. The manifold probe part # is WPW10082831. Are the spray arms turning freely? Is the manifold plugged into the pump / motor assembly? Remove all racks. Unscrew the Phillip's screw in the middle bossed area of the manifold. Remove the manifold by unclasping it from the top of the Accumulator assembly. Then there are top 3 - screws that hold it onto the pump assembly. Cleaning it out will help drastically. Use Glisten dishwasher cleaner monthly to keep it all cleaned. Glisten part # is W10549845. Hope this helps. Thank you. Read More... Answered by AppliancePartsPros.com | Tuesday, July 12, 2011
