Hope somebody can point me in the right direction. My Maytag MAH8700 was delivering the "ND" code, I replace the drain pump once before and examined it again. I found the housing filled with dirty/black water (probably a bad gasket) and concluded that this may well have been my issue. I installed the new drain pump, but the results were the same, ND.
In "Service Mode" I performed the Board Input and Board Output test, all tested fine except two. On the Board Output when trying to test the Main Relay I receive a code of "ot", also when testing the Drain Pump I am getting the same "ot" code (pump NOT turning on or off).
I can't seem to find any reference for what "ot" means and what my next step should be. Any help would be appreciated.
