Mark D Cedar Park , TX November 17, 2014 Appliance: Model GHDT168V55SS Dishwasher leaking below door Lower spray arm had melted after becoming stuck on the heating element causing the spray to directly impact the seal at the bottom of the door. I pushed the elevated heating element down to prevent further interference and replaced the spray arm. All is well. The spray arm removes easily if one lifts it while turning counter clockwise.
