LG Dishwasher HE error code. What is this part?

I have an LG LDF5545ST dishwasher. Recently, it started showing an HE error code, indicating a problem with the heating element. I pulled out the dishwasher, turned it over, and removed the bottom cover. The issue is that the connection to the heating element corroded:

I confirmed that the heating element resistance is correct, then soldered a spade terminal onto the wire to verify that it works (it does). I'd now like to make a permanent fix.

The part that is corroded is a small connector with a ceramic base and two spade terminals. The part is easily removed, but isn't identified separately on the parts diagram. Rather it's part of the pump case assembly (Part #ABT72989202). On this dishwasher the heater element cannot be replaced separately from the ($200-$300) pump case assembly.

Since the heater element works, I'd like to replace the electrical connector.

The body of the connector as shown below is 17mm wide, and there should be a spade terminal coming off to the left and right from the main body.

On the back side, I found the following numbers that may or may not be part numbers. I've had no luck finding the part online.

Any help identifying this part and a place where I can buy it would be appreciated. Thank you!
