4055921177 Genuine Drive Belt M23 for Electrolux Group Washing Machines, Older Number 38528411, Not the Same as 38528403

Part 4055921177 is a genuine Electrolux M23 drive belt, also known by the older number 38528411. Don't mix it up with 38528403, which is a different belt, so check which number your machine needs. Fit this one when the old belt has snapped, stretched or started slipping. No model list is on file for 4055921177, so the number on your old belt or parts list is the best guide.

Washing machine not agitating or spinning? Check the drive belt

On belt driven machines, the drive belt carries power from the motor pulley to the transmission or drum pulley. As it ages, the rubber glazes, cracks or stretches, and it begins to slip under load. Signs include a motor that hums or runs while the drum or agitator barely moves, a burning rubber smell, squealing during spin, weak agitation with a full load, or a belt found lying in the bottom of the cabinet. A belt that keeps coming off can point to a worn pulley or loose motor mount, so check those while the panel is off.

Fitting the M23 belt

Unplug the machine and turn off the taps before removing the back or base panel. Note how the old belt is routed around the pulleys. Loosen the motor mount if the design allows, slip the new belt over both pulleys and set the tension so it deflects only slightly when pressed midway. Tighten the mount, turn the pulley by hand to check tracking, then test on a short cycle.
