Turn washer on so that timer is running, lid closed. Unplug washer and check continuity (zero ohms) from power cord neutral (large blade) to the wht/blk wire on the motor connector. If no good, check to gray wire. Also check from power cord hot (small blade) to motor orange and blue. You should have continuity to one or the other depending on where you are in the cycle. If the motor switch is good, you should have it to both. If no good, either timer is faulty or there is a wiring issue (broken wire, burnt/corroded connection...etc.).
