Dishes are no longer getting clean. Most are, but several are not. It does not matter if on the top rack or bottom rack or if they are in the silverware rack.
Answer Hello Bob,
This is most times caused by a low water fill. The unit should fill to within 1/2 inch of the bottom of the heating element. If you are not filling enough, the water inlet valve is the most likely cause. You should ensure the unit is installed in a level position for proper water fill. If the unit is filling satisfactorily, the issue will be due to poor water circulation. This can be due to stopped up screens and spray arms, foreign matter in the circulation pump impeller or a defective circulation pump. When loading the unit, you should ensure that all spray arms can move freely without hitting any of the loaded items.
We always have to run the dishes through at least 2 times to get them even close to clean.
Answer Hello Dante,
Sounds like you are either using a cheap detergent or there is a heating circuit failure.
