The gasket used to prevent leaks makes a perfect hiding place for mold. As opposed to the old design of the top load washers, it doesn’t have the seal when closed and it gives the drum time in between loads to dry out and mold isn’t an issue. Soap suds, fabric softeners, cold wash cycles all play a part in keeping the mold around.
If you’re pretty sure it’s the drain pump, you’ll need to call a professional out to check. It may be a good idea to remove the clothes and as much water as possible by hand before calling anyone out to work on the unit. This is where a good shop vac can save lots of time.
