I have a bosch dw that just began to show 1 at the end of the cycle. Reading through the forums this is a very common problem with bosch. I removed the control module and I can see the burnt solder connection. Called Bosch and it is covered by warranty but not labor. I wouldn,t mind paying for a repair, but this sounds way too common. I payed $569 for this washer and now probably $100 repair call. The washer has been good to this point but bosch should stand behind their product. The lady I spoke with at Bosch said that this is not a common problem.
This is a common problem. If it will cost you about $100, do it. The part itself cost much more and is available through Bosch only.
