What causes the Remeha 0$ fault?

This fault happens when the boiler loses its electrical supply immediately after a different internal problem caused it to shut down. Because the power was cut or interrupted during the shutdown process, the boiler's computer has 'forgotten' what the initial problem was and cannot safely restart. It is often caused by a failing main circuit board or a loose electrical connection that fails under the stress of a system error.

Typical repair cost £100-350 (including labour)
