Again, thanks for answering my questions!
The water flows, not drips, out of the lower right corner of the door.
I removed the pump cover today and found the seal in very good condition. When the seal was cleaned of some whitish deposits, carefully replaced with the black rubber edge slightly higher than the groove in which it fits, and the screws firmly torqued by hand, the overflow in the right corner returned. The water does not spurt out but flows out quickly with a pint coming out within a minute.
The screws for the pump cover are "staninless" steel but show some rusting under the head area on the screw shaft.
