The MDB3700AWE is a built-in dishwasher whose faults tend to show up at the drain pump, check valve or sump filter long before anything else gives trouble. Because several builds share this base number, the plate inside the door or on the cabinet is the reference a parts order should use.
Stick to clearing the filter, checking the spray arms spin and loading properly and switch the appliance off at the breaker before looking at anything. Internal diagnosis needs meters and training.
