HELP!

So sick of replacing our clothes and having to restart machine over and over due to F20 error code ughh so damn frustrated I have had my set for almost 2 years and after a few months of having them I started having problems with it! We've had it checked out so much its annoying already, the fact that I have to unplug and restart my washer over and over again just to get it to finish a load is costing an arm and leg on my electricity bill! So I'm with whom ever is gonna start a class action suit on this company for there uncompitent machines! If u need to contact me due so at tami361@yahoo.com
