I’ve had a leak in my Whirlpool WDT750SAHZ for some time. I’ve replaced the lower spray arm (WPW10498900), lower door seal (W10909089), and main door seal (W11177741), but am still getting leaks, mostly from the corners of the machine.
I’ve noticed that the new door seal has about an inch less excess extending into the tub. Not sure if that’s relevant.
