Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
have you cleaned the filter real good, also along the front where the door close the lip collects a lot of particles and crap, take a towel open the door and wipe along the front edge where the bottom of the door is , is it filthy? black stuff?
ok, well theres food particles in the sump area then, this means removing the machine form the cabinet and tearing down the pump assembly, this is a big job, wish there was an easy fix . we have the same type dishwasher and we used Glisten and it did the trick for ours, they sell that at most grocery stores. it should be used once a month, its better than dish washer magic, I would try this before tearing down the machine, thanks Bryan,
I purchased the Glisten as recommended and it did not solve the problem. What appears to have been the problem is that the rinse agent dispenser was broken. Upon replacing this, the glasses are clean again.
