Manufacturer manualEEPROM error | Electronics defective
Shared across the ecoTEC plus range
This code is shared by the boilers in this range, which use the same control board. It may not be printed in this exact variant’s manual.
What causes this fault?
This fault occurs when the main control board suffers a permanent memory failure, meaning it can no longer remember the specific settings required to run your boiler safely. The most common reason is a physical hardware defect within the internal circuitry, often caused by age or an electrical surge that has damaged the board’s microchips.
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.
