Some owners of Bosch dishwashers feel worried when they see h01 (h: 01) or h02 (h: 02) on the display, because they mistake these indications for errors. However, these are just start-up time indications, which denote delayed start of wash cycles. For example, h01 (h: 01) means that the cycle will start in one hour, h02 (h: 02) – in two hours. In Bosch dishwashers, delayed start time ranges between 1 and 24 hours.
