The boiler works regularly but does not ensure the stability of the hot water
temperature which, however, is delivered at a temperature of approximately
50°C.
Contact the Technical Assistance Centre.
Fault code 91
The boiler has a self-diagnosis system which, on the basis of the hours totalised
in particular operating conditions, signals the need for maintenance or cleaning
of the primary exchanger (alarm code 91). After cleaning using the kit supplied
as an accessory, reset the hour counter as follows:
- disconnect the mains power supply
- pull out handle A (Fig. 12.17)
- switch on the boiler by pressing and holding down button B (Fig. 12.17) for
at least 4 seconds
- to check the counter has been reset, switch the boiler off and back on
again; after all the digit segments have lit up, the counter value will be
displayed.
To check the number of hours, multiply the value by 100 (e.g.: value displayed
18 = 1800 hours totalised – value displayed 1= 100 hours totalised).
N.B.: perform the counter reset procedure every time the primary exchanger
is thoroughly cleaned or replaced.
