my 3120 w pc upgrade runs about a minute. then shuts down. It will do this and only this each and every time I ask it to wash the dishes. There is water remaining in the bottom of the unit. But I've checked the drain and theres no issues. SO what gives I wonder. I live way out in the sticks so a repairman is almost not an option....sure was a nice working unit....right up until it wasn't !
