When Control Board Replacement Is Needed
Replacement of the control board becomes necessary in these situations:
- machine does not power on at all — no lights, sound, or display activity
- freezes during self-test or warm-up phase and does not progress
- same error codes or messages persist even after reset
- buttons or touch panel do not respond or respond incorrectly
- boiler does not heat, pump does not start, valves do not operate — despite power being present
- errors such as “electronics error”, “main board failure”, “control unit”, “E90–E99”
- machine stopped working properly after power surge or thunderstorm
- visible severe burn marks, charred traces, large darkened areas on power section of the board
- board repair is technically impossible or economically unjustified
- machine randomly reboots or shuts down
- all settings and recipes reset after every power-off
Replacing the control board is the fastest and most reliable way to bring the machine back to full operation when the electronics are severely damaged.
