I just bought a Bosch too - mine smells like something died inside. We don't dirty a lot of dishes so it's several days before we run it. However, it smells so bad that we have to hold our breath to load it after a few days of sitting.
We went to Lowes to let them know and they gave us some dishwasher disinfectant to try and told us some bs about it may have a stale smell when it was run and tested at the factory.
