I followed the instructions to verify whether the problem was the control panel or the control board. Basically, if you disconnect the control panel from the control board, reconnect the AC, and close the washer door and the pump comes on and runs for 2 minutes before turning off then the problem is with the control panel. If nothing happens then the problem is with the control board. For me the problem was the control panel (pump ran for 2 minutes and then shut off) which is a good result considering the control board is much more expensive. I replaced the control panel and the machine is running like new. I might add that it's a shame that the little buttons on the control panel fail so easily.
