Poor wash performance - spray action not energetic enough
After 7 years of use, our Maytag MDB7130 is showing poor wash performance because the water is NOT being sprayed energetically enough. I cleaned screens and that certainly restored performance for a while but now I need to clean screens more and more often. Now only 2 days since screens cleaned and washing performance is just abysmal. Plenty of nice hot water in tub, just doesn't splash as hard as before, e.g. the soap in the dispenser isn't even getting exposed to the water! Going to pull arm and filter cover off and clean again but I may have to disassemble even farther. Any ideas?

All of the water coming to the upper spray arm comes through the feed tube. If the feed tube is blocked or the probe flapper is hung open, water will not flow properly to the upper spray arm. Be sure that when you push in the upper rack the manifold probe is in position in the feed tube. Try adding more water in the tub to see if the upper spray arm starts rotating. Other possibilities; low water charge, cracked spray arm & poor wash pump performance.
Probably a blocked spray arm (part that spins around). Remove each of the spray arms and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results. Hope this helps
Probably a blocked spray arm. Remove the top spray arm and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results. Yes there will also be a filter in the base of the unit to clean. This needs to be done regularly to avoid food getting into the working parts of the unit.
It MIGHT be a bad "impeller". This is a little propeller-like device that chops up chunks of food and in some cases performs part of the pumping action of the water. Not an expensive part, but sometimes a pain to replace.
A common cause of poor washing is improper loading—dishes block or impede the spray arms or prevent the soap dispenser from opening. On the other hand, if your dishwasher has chronic problems with washing, the problem may not be your dishwasher. Your home's water pressure may be too low, the water may be too hard, you may not be using the right amount of detergent, or the water temperature may not be hot enough
