The very first thing you can do is check the wiring on the inside of the dishwasher. Don’t ignore any loose or burnt wires. Carefully check all the wiring and connections. If you find anything out of the ordinary, note it down.
If you are unable to see any apparent visible damage, then take a multimeter and test each wire for any short circuit or damage. It happens when the cable is broken under the protective insulation cover, and it can’t be detected with the eye. If you see any kind of fault in the wire, use the wire strippers and remove the faulty wire and replace it with a new one.
Another reason for the Bosch dishwasher error code e02 is due to the malfunctioning control module. Your heating element is an integral part of the system that controls how hot your dishwasher gets. It uses electricity to make sure that the dishes that you place in it stay warm. So if the heater element is not working correctly, hence it cannot supply heat water for washing dishes.
The thermostat that you can find on your unit could be completely broken. If it does not work, check that it is connected to the power. Your dishwasher may have an overload warning light that means the thermostat has overloaded, so make sure it is clear of the overload. It may also need to be replaced with a new one.
So you need to check the below elements for E02 Error.

The heating element relay is normally easy to find on the control module. The heater and component are connected by at least one cable. If you find a faulty wire, then you can contact a professional technician to replace the damaged wire, And that’s going to be cheaper than buying a new control board.
But many a time, the control panel is damaged and is beyond repair. In this scenario, we suggest you replace the old heating element relay with a new one. It will also be a much cheaper option. You also need to consider the service cost and compare it to the cost of getting the new one. Whatever cost you less, go for it.
