I have a Kenmore HE3 front loading washer. I keep getting error 6. Manual doesn't address error code 6. Any ideas?

F/ 06 is a drive motor Tachometer Error

The control is unable to properly detect motor speed and machine will shut down.
If a failure occurs at high speed , the door will be unlocked after 3 minutes.

When my he 3t had problems, I found the technical documentation inside the machine washing taped to one of the inside walls.

F/02 long drain
F/05 water temp sensor error
F/07 motor control unit error

Also: the error "Sud" can mean too much detergent but it can also mean a problem with the drain pump ( a clog in the pump filter). Clean out the filter before the drain motor goes.
