Product review (5 stars): Solved my leaking JetDry issue
A little while ago, I started noticing that JetDry was leaking down my dishwasher door and it appeared to be coming from the cap area.  I found this replacement cap and the leak has totally stopped, the gasket must of worn down or warped or something on the old one.
My dishwasher is a Whirlpool GU2700XT
