E50 on Baxi Duo-tec Heat

Your boiler has lost the ability to accurately measure the temperature of the hot water, so it has shut down to prevent the system from overheating.

Call an engineer soon

Book a Gas Safe engineer within 24 to 48 hours. Your boiler may be unsafe or could break down completely if left.
