I have a Bosch Nexxt series front load washer, (model number WFMC220RUC/15) that is giving error code E13 and doesn't drain properly. I have opened the drain trap in the front and found a few coins and such. I cleared all that out, but the problem persists.
I then removed the drain tube on the back to see if it was blocked. Water flows freely through the tube, but when I stuck a finger into the pipe it is attached to on the back of the machine it seems fairly full of gunk.
Does this seem like the source of my problem, and if so, how can I clean it out? It doesn't appear to easily detach from the machine.
