Started with front panel, two screws at bottom. Then disconnected the two bolts securing the top to the side panels. Then took the back panel off the control panel. Disconnected the hose that connects to the wash size dial. Disconnected the bolt holding the filler on. The plastic tab was broken. Then opened the top up, disconnected the hose clamp from the mixing valve, which was tricky. Then reinstalled the new filler spout.
