Unplug drain pump stick you meter leads inside the connector set to vac, put on drain and spin, start. Lid locks, basket jiggles then pump should come on with 120vac on that plug. No 120 and you have a good tag, you have a break in the harness most likely so just unplug drain pump connector from pcb and ohm harness end to end not continuity though even a fried wire will beep. Should be 0.01/0.03. Anything other than that you found the bad side. Then walk that line with needle probes to isolate break, cut, splice, do laundry.
