There are countless stories about Bosch dishwasher owners being confronted and confound with h01 (h: 01) or h02 (h: 02), which appear as they try to run their machines. There is some good news: these are not errors! These messages appear when users accidentally hot the start-up timer menu and delay the cycle start. The h01 indicates nothing but the fact that you will need to wait an hour or two (h02) before the cycle starts. The maximum delay time for most Bosch dishwashers is 24 hours.
