If you ever run into one of these overly-"smart" GE front loaders with a "smart" dispense pedestal, Brother nickfixit offers these sage words of advice:

Run! Do not get involved! The design is so flawed you can not fix it so it stays working. You'll be replacing the pump assembly and cleaning ever inch of hose, every connector, and the tanks. Over and over and over......

We will not warranty or cover these with any service contract, it's a total looser with certain multiple unpaid recalls
