The causes of error

Error code E 01 indicates an issue with the heater. Its contacts might have burnt; therefore the device does not receive a signal from the board that the element is on. Another cause is the burnt heater itself – this happens because of calcification caused by the use of hard water.

You need to check the heater to solve the problem. The difficulty is that the heater in Bosch dishwashers is a one-piece unit, with slots for hoses and nozzles. If it has no screws to take it apart, so you will have to replace the entire device.
