Water comes out of the pressure relief
valve
Check if the filling cock is closed tightly (see
"Refilling procedure" on page 12).
Check on the pressure gauge that the pres-
sure in the central heating circuit is not
close to 3 bars. In this case, temperature
rise in the circuit can cause the pressure
relief valve to open. So that this does not
happen and to decrease the pressure to a
normal value, it is advisable to vent some of
the water in the appliance through the bleed
valves present in the radiators.
Reduced domestic hot water tempera-
ture
The likely causes may be impurities caught
in the domestic hot water flow switch filter or
limescale deposited in the domestic hot wa-
ter heat exchanger. It is advisable to have
the appliance cleaned out by an Authorised
Service Centre Engineer.
Should occasionally leak from the boiler
Shut off the valves positioned under the
boiler to page 16 and call an Authorised
Service Centre Engineer.
In this case or in case of prob-
lems other than those men-
tioned here, switch off the boil-
er, as described in section
"Switching off" on page 16
and call a competent and re-
sponsible Service Engineer.
