This Maytag is 2.5 years old with no issues until a week ago. All cycles run fine and dishes in bottom rack are washed well as always. No leaks, no loud noises.
However, the top rack dishes are poorly washed;; a recently upturned glass had no water in it at the end of the cycle. Water level during wash level seems OK (just below center filter level). I hear some 'bubbling' during the wash cycle inside front right corner of the machine, but can not tell if that is a drain valve leaking. Perhaps pump issue? Thanks for any advice!

Hello,

You may want to start the troubleshooting from checking the chopper (#6 at the diagram). You can find more useful information in one of our previous threads: whirlpool dishwasher
