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.
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.
I purchased a wonderful portable dishwasher at a garage sale for $20. The woman had just redecorated her kitchen and was selling the relatively new portable model. All it needed was a new caster and a faucet adapter. After ordering the parts, they arrived in a couple days, and after less than 5 minutes of installing them I had a "new" dishwasher that works like a champ! Thanks for making this so easy!
