Is water inside a washing machine motor normal?
Motors that use cooling water normally Chanel the water through the motor without any water coming in contact with the windings.
The insulation on motor windings is very thin and a motor may run for a while when wet but water usually will Usually cause a failure . I bake motors out that have gotten wet and they are ok in many cases but if it fails on start up they are usually toast. So dry the motor out reassemble and good luck.
If you have a small electric heater put the motor windings in front of that for 6-8 hours I have saved large electric motors by doing this when they did not fit in my motor oven just the hot air blowing over the coils will dry it off and reduce the chances of the motor shorting out soon because of moisture.
