BoilerFaultCodesTechnical description
EEPROM error
What causes this fault?
This fault occurs when the boiler's internal memory chip, which stores critical operating data, becomes corrupted or suffers an electrical failure. The most common reason is a power surge or natural wear and tear of the electronic components on the main control board, which prevents the computer from reading its own instructions. Because the boiler no longer knows its safety limits or settings, it shuts down immediately to prevent unsafe operation.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
