Removed three 1/4" hex head screws from the back panel, tilted it toward the front of the machine, and slid it to the right to remove the upper front panel. Two 1/4" hex head screws and the wire clip holding the fill tube. Carefully remove fill tube from water valve. Then reverse the procedure. The control assembly had 5/16" hex head screws, three for the dials and a nylon bracket aligning the left side of the control arm and the right side with two 5/16" hex head screws with four plug-ins. The fifth plug-in with the wire loop on the top has to be used from the replaced assembly, being careful not to bend the pins. The control assembly needs to have the dial controls inserted into the assembly when reinstalling the board. Patience.
