Do-It-Yourself Story

Removed and cleaned plastic filter strainers (located in the bottom rear of the dish compartment) that was packed with sediment. In doing so I found the filter gasket assembly badly deteriorating (rubber coming apart with the simplest of touch). While trying to remove the filter gasket, I broke the lower spray arm assembly due to the plastic being brittle. (Unit is over 10 years old!) Then, while ordering parts, I read that the Piston & Nut assembly is the typical cause of the condition I was experiencing. Since it was only $10, I figured why not. All 3 components were exceptionally easy to replace and dishwasher is back to normal operation.
