Water leaking under the dishwasher
I looked under and found that 2 brass nuts that secured the heater element through the base housing of the dishwasher has split down each side of the nut and no longer was tight enough to keep water from leaking around either end of the heater element. I powered down the dishwasher at the circuit breaker and then reached under the dishwasher and pulled away the 2 wires that were attached to each side of the heater element. I removed the two nuts and replaced them with the parts I ordered from partselect.com. I then put the appropriate wires back at the end of the heater element and ran the dishwasher to check for leaks. No leaks... it was fixed.

Water leaking from under dishwasher
Removed lower trim covers (2 Phillips screws) disconnected power supply at breaker box. Removed wire from heating element, removed (broken) brass nut, unclipped heating element and removed. Removed flat washers and replaced with new grommets. Kind of tricky getting them in there. Also had to lube them with silicone to get the element back through. Installed new brass nuts and installed wire connectors. Reset breaker and started diswasher to verify repair. No leaks, working just fine, reinstalled lower trim covers

Water leak underneath dishwasher
Unplugged dishwasher, removed the 2 wires clipped to the heating element, removed both cracked nuts, replaced with new nuts from PartSelect, clipped on wires, plugged in and did a test cycle. Based upon service quote from Best Buy, I saved myself $125.00 for just the call out, not including parts and labor.
