I'm looking for the manual for a Gaggenau GM926-710. It's about 10 years old+. The machine cycles for 3 hours on normal wash. I've ordered a new circuit board, which will arrive in 3 days (mainly because the kids have pushed all the buttons so many times, they no longer allow you to change the settings.) This probably won't solve the issue of the 3 hour cycle. Any help appreciated. Thanks, Matt
