Dishwasher leaking in what seems like a strange way
Woke up this morning to an E15 error code indicating water in base of dishwasher (washer had stopped overnight, dishes still dirty).
Pulled dishwasher out and watched it while running normal cycle to look for the location of the leak.
• no leak while draining
• no leak while filling
• leak appears with start of prewash cycle, splashing pretty heavily out of the two holes circled in the picture
Behind those two holes and that entire piece of plastic itself there's nothing but a solid piece of styrofoam. The inlet valve doesn't seem to be close enough to be the source of the problem.
I guess its leaking out of the tub from the circled area in the second picture? Is that possible? I don't know what's behind the plastic there or how I would go about taking it off...
BTW the black gasket that seals the tub's back wall looks perfectly fine. If it were to be leaking there, I don't think it could be leaking the amount of water that I saw coming out of those holes.
Thanks in advance for any advice given :)
