Reset function
In order to reset the boiler’s operation in the event of a
fault, it is necessary to access the fault description screen.
If the lockout is of a non-volatile type that requires a reset
procedure, this will be indicated on the screen, and can be
performed by pressing the “ok” button on the REC10CH.
At this point, if the correct operating conditions have been
restored, the boiler will restart automatically.
There are a maximum of 3 consecutive attempts at a release
by the REC10CH
,
should all 3 attempts at reset fail, the
appliance will require to be isolated briefly from the electrical
supply in order to carry out any further reset attempts. Once
the electrical supply has been restored, further attempts
at reset can be carried out. In case of all the attempts are
exhausted the definitive fault E099 occurs on the display.

If the attempts to reset the boiler are unsuccessful,
please contact the Vokera technical helpline.
For fault E041
If the pressure drops below the safety pressure limit of
0.3 bar the boiler displays the fault code “E041 - WATER
TRANSDUCER LOAD THE SYSTEM” for a transitional time
of 30 sec during which it is possible to open the external filling
tap until the pressure is between 1 and 1.5 bar.

If the pressure drops frequently, contact your installer or
the Vokera customer care centre.
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 an engineer will be 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 primary exchanger (alarm code
E091). Once the cleaning operation has been completed,
reset to zero the total hour meter following the procedure
indicated below:
- select TECHNICAL EXHAUST PROBE RESET
CONFIRM or CANCEL.
