Bought dishwasher second hand. Previous owner had stored in garage approx. one month before I picked up. Had handyman install unit next day along with new sink and disposal. After installed, door is leaking steady drip at corners. Have replaced rubber "boots" at corners where door closes, still drips. Also water won't drain out at end of cycle. Handyman is to return tomorrow. Asking here to try and have info ready for him. Thanks in advance for help!
