For fault E060
The boiler is working normally, but does not provide any stability of the
domestic hot water temperature that, in any event, is supplied at a
temperature of around 50°C. The intervention of the Technical Assistance
Service is required.
For fault E091
The boiler has an auto-diagnostic system which, based on the total number
of hours in certain operating conditions, can signal the need to clean the
