FD number tells you its age, it was manufactured in September 2014 so almost 7 years old.
E02 indicates fault with electronics caused by faulty operating module.
However, please try this to solve the issue:
You will have to unplug the appliance and pull it out, then tip it backwards by around 45 degrees so excess water drains off completely.
After you have done this, check the drain hose where it connects to house drain and make sure it is not clogged.
Then please clean the mesh filter from inside and make sure it is not blocked.
Now, reconnect everything and plug it back; select any program.
It should work however, if the problem occurs again you will have to replace the operating module.
The cost of repair will be around £66 + repair charges (£99 if done by Bosch).
Please let me know if you need me to clarify anything or if you have any additional questions-I am happy to help!
