I replaced a dishwasher and the new dishwasher isn't drying like it should be (The old dishwasher didn't have this problem). The retailer told me that the drain hose might be kinked. The yellow line represents the route I have. The standard drain hose wasn't long enough so I spliced together another hose to make is long enough. When the drying cycle is done, the unit is really wet on the inside, but no standing water on the bottom.
My best guess is that the route to the drain is too long/steep and the water is draining back into the dishwasher.
Any thoughts on how to solve this issue would be greatly appreciated!
