Thank you for choosing Manage My Life. There are several possible reasons why your dishwasher is leaving particles on your dishes.
Check the water level after it has run a few minutes. If there is a siphon problem the water will drain out as the dishwasher washes.
Some general things to check are at the end of the cycle when the dishwasher finishes the dishes should be almost too hot to touch. If the dishes are not hot at the end then the water heat function in rinse is not working. If the dishwasher does not heat the water it will not clean well.
The dishwasher needs to drain completely. If the dishwasher does not drain then the rinse can be with soapy water and leave a film on the dishes.
If some items are clean and some are not then it may be a spray arm or circulation problem. You can place cups in the corners of the rack and see it they all get the same amount of water. Usually when the upper spray arm is not rotating and the dishes are not cleaning very good there is either a water fill problem or water circulation problem.
The other possibility would be a restriction in the pump/motor assembly, not draining out or poor wash motor performance.
