E:13 We continue to get an error message of E:13. What is this?

Hello and welcome to fixya.

The E13 error code on the WFMC series Bosch washer`s refer to a drainage problem, ( or in Bosch terms "pump time exceeded" )

What you may have is either a clogged pump, improper detergent being used, ( must use "HE"/lo-sudsing detergent ) hence suds not allowing a proper drain cycle, or wires loose at the pump...the later being the least likely.

You haven`t mentioned if you`ve checked the pump...of course why would you if you didn`t know what E13 meant...

Anyway, here`s the most likely way to remedy a E13 code.

**Unplug the washer from the wall or turn off the breaker before attempting any repairs**
