Guys the curved end of the existing 'drain heater" wire goes over the heater.
The straight end of the "drain heater" wire goes in the drain.
You will see some attached to the e-coil then go in front of the heater then in to the drain hole.
Too little heat transfer with this method.
Before they started putting the drain heater in these units I made copper wire heater assist and attached to the GLASS heater.
After they supplied the wire I discarded it (TOO SHORT) and replaced with a longer wire.
I have done hundreds and never had a heater failure due to the wire attached to the heater.
I used to use the aluminum ground wire supplied with Maytag washers until they quit supplying it.
If you can get 10 or 12 gauge aluminum wire,it works best for wrapping on glass.
