If your Bosch dishwasher displays an E01 error on the display, do not rush to panic - this is how the self-diagnosis system notifies you of a breakdown in the heater, which you can fix yourself. You may also notice that the water in the machine has stopped heating or the equipment has stopped and does not start the washing cycle.
You can find out why the Bosch dishwasher shows error E01 on the display by looking at the instructions or reading the decoding below.
The meaning and causes of occurrence
DTC E 01 in the PMM indicates problems with the heater. Perhaps its contacts have burned out, so the device does not receive a signal from the power-on board. Another reason is that the heater itself burns out, this happens when scale is formed due to hard water.
To solve the problem, check the heater. The difficulty is that in the Bosch dishwashers, the unit with the heating element is solid, with leads for hoses and pipes. If it does not have screws for disassembly, you will have to completely replace the entire device.
How to fix the problem
First, make sure that the system generates an E1 error not by accident. To do this, reset the icons from the screen:
- disconnect the machine from the network for 10-15 minutes;
- run the PMM and look at the display.
Is the error on? Then proceed to check the heater.
Important! The flowing heater for the Bosch dishwasher costs from 3,000 to 10,000 rubles. Therefore, think carefully and make sure it is malfunctioning before making a replacement.

- Disconnect the equipment from the network, water supply and sewage.
