Watch the video you recommended and do the valve replacement yourself! I bought the part online at a famous auction site (can't give the name or it will be blacked out). I paid $23.10 with free shipping. It took about a week to get here. You need Part # 607335. The seller's name was *buyitnow*. Search that auction site using the words Bosch 607335 Valve. You'll find it. Cheaper than a service call, which around is a minimum of $75.
