The start light is flashing at what seems to be the end of wash. the done light used to come on. the washer is only a couple of months old.

I would replace the timer.

Maybe the machine is telling you that your load is uneven, When going through a spin cycle it will detect if the load is too heavy on one side. Just open the door and spread the load evenly. good luck.

Hello- If the drum does not turn in either wash or spin I would check the belt drive.

Hi,

Thanks for writing to Fixya.com.

This sound like a loose connection in the wiring in the machine. The probability is that the vibration from the machine is enough to work some connections loose. If you have someone competent to do this, then check that all connectors are pushed firmly onto their circuit boards.
Thanks for contacting Fixya and please accept the solution if it has helped you.

If nothing works you have to either,
1. change your washing machine/filter
or
2. Use a Lint Roller to remove lint on dark-colored clothes
