Drainage Failure, Sump Pump Replacement

My Dishwasher Does Not Drain. Itis Not Due To A Kink In The Hose Nor The Sink Drain. I Suspect …do I Need To Remove The Door To Access The Sump Pump And What Is There To Do To Access The Solenoid Valve?
THE MODEL NO. IS: SHU8805UC

The model number you posted does not come up. Is it an American model? Verify and repost it.
