The Dispenser Drawer on my Whirlpool integrated dishwasher will not open when on any cycle, opens manually no problem not broken. Spoke to Whirlpool they say it is operated by water. Dishwasher very clean and we have cleaned all parts inside nothing clogging it up.
remove decor door and look in small gap in outer door,top left hand . you will proberly find that the small wire plug that fits into the dispenser as fallen out.
