I took the air vent off (part 8545533) and it was full of gross slime and doesn't vent well during drying cycle. Cleaned it and now the issue is why it happened. The motor opens and closes the venting seal but there's a dual seal that seem to be 'just' sitting there. They're curled a bit at the ends which allows a opening during the whole wash/dry cycle. There as seems to be water buildup there too when the unit runs. Are these seals suppose to be flat and free moving or sealed closed to the vent?
