How to fix Bosch E03
Turn the breaker off for 30 seconds
Shut off the circuit breaker that feeds the fridge, wait half a minute and restore it. See whether the code is back once the display wakes up.
Make sure the panel is dry
Wipe the dispenser panel with a dry cloth. Water or ice drips around the buttons can make a touch panel act up.
