detergent door leaking - Neptune-

Greetings all. Just bought this unit off craigslist. It was in someone’s garage for the last year or so. The unit is two years old, came with delivery info from factory. Plugged it in and found a leak where the drain hose comes off the pump and got that fixed. The problem is in the "Rinse and Spin" cycle, a fair amount of water comes out of the detergent drawer. During a regular wash it doesn’t leak at all. During the rinse and spin it seems that water is sprayed into all three of the bays, and it ends up coming out around the drawer and running down the front and inside of the machine. There is no gasket on the drawer. Should there be?

TIA for any help.
