I have a Siemens washer

The timer/control board in your washer has failed.
Your Washer is a re-branded BOSCH.
SEE THE CONTROLLER HERE

At $350+ for a new board - you may be better off investing in a new machine with a warranty.

The link above will allow you to order the controller as well - if thats the route you choose.

It is simple plug and play - and you can do it yourself in a few hours.
Most of the time is spent disassembling the cabinet.

Thanks for using FixYa!!
