d.2 Low Information

Your boiler is currently taking a temporary break from heating after successfully reaching its target temperature to prevent it from turning on and off too frequently.

Monitor it

This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.

Technical description: Heating system max. off-period

What causes this fault?

This status occurs when your boiler has reached its required temperature and needs to wait for the water in your radiators to cool down before firing up again. It is a built-in protection feature designed to stop the burner from turning on and off too rapidly, which saves energy and protects the internal components from unnecessary wear. Once this brief 'anti-cycling' timer finishes, the boiler will automatically resume heating your home.

This is more common during autumn and spring when the weather is milder and your home requires less intensive heat to stay warm.

Typical repair cost £0 (including labour)
