WHAT is that noise?

[jmurray01]

If a washer motor is anything like a Vacuum Cleaner motor, it'll over rev with no belt, so I wouldn't recommend it. Just as I wouldn't recommend running a Vacuum Cleaner with no belt, with the exception of older models (Juniors for example) which deliberalely lifted the belt off the motor pulley when the hose was fitted.

the fan on the vacuum cleaner motor serves as a load without the brush belt-the fan should be a sufficient enough of a load on the motor to prevent racing or overreving.I am not famaliar with the motors used in washers out side the US-do these motors have an internal fan-if so should be safe to run it without a belt.If it DOESN'T have a fan-then wouldn't do it.and Vacuums--such as direct air uprights-have a fan inside the motor for cooling-this serves as a min load,too.
