What does the Ideal 2 / F fault code mean?

Your boiler has detected an inconsistent temperature reading between its internal sensors, causing it to shut down to prevent damage.

How much does it cost to fix Ideal error code 2 / F?

Typical repair cost for the Ideal 2 / F fault is £150-250 including labour.

The difference in heat between the safety sensor and the supply sensor is too large or the supply and return sensor have been interchanged.

This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
