I had the same problem and I did the same repair with mine, see here:
http://www.xoutpost.com/bmw-sav-foru...er-broken.html
I was unable to find the MC33286DW (it is no longer produced) and instead used a MC33289DW bought from digikey for about $4. The ICs were almost the same, except pin 10 -- you'll see what I mean when you compare the datasheets. The only problem was that the washer wouldn't work after the repair (not sure as a result of pin 10, or some other failure on the board.)
I am by no means an expert, but I didn't have any problems with the desolder/solder of the SMD IC with a plain soldering iron with small tip and some flux.
The repair lasted about 16-17 months before the same IC burnt out again. There must be some other defect on the board and I'm surprised there aren't more failures listed here.
I tried the repair again but some of the pads lifted when I desoldered and just ended up buying a complete new unit. I wish the circuit boards were sold separately as the motor is fine. I should have looked to see if the circuit board on the new one was the same.
Let me know if you have any questions or need help. Good luck.
