Miele W1903 owner's manual

Actually this is what's happening (posted it earlier) then a friend said something about reset which I was unable to find:

"W1903 when in diagnostic mode, washer fills, agitates and spins properly with an empty tub (I.e. No clothes present). With a very small load, works but seems to struggle and with a larger load it can't agitate or spin, 'tho it tries. Suggestions please. Thanks"

Brushes are fine, machine is level, empty it does fine, will do small/medium loads with a bit of a struggle. Larger (and not THAT much larger) loads the thing will not agitate (tries, but just can't quite get there and spinning forget it!). Funny thing is, when I switch it to spin (i.e. not part of a program) it WILL drain and spin even the large load. Really can't figure this thing out. I do appreciate all of your help.
