I have a bosch nexxt wfmc 6400uc front load washer that is not working. It dispenses detergent and then clicks to ready and just sits there. Sometimes it will go through the full cycle but it is hit or miss. We have tried everything and had a repairman out that ran diagnostics. No issues and of course the problem did notmpersist when he was there. Does any one possibly have a suggestion and/or a copy of the service/diagnostics manual so we can do this ourselves? Any help is greatly appreciated.
