Question about Heating & Cooling
SOURCE: ariston micro genus combi boiler
having found a circuit diagram, realised that the divertor valve was electrically operated.i unplugged this then unclipped the motor from the valve body,the diverter valve is spring loaded and once i'd removed the motor the spring raised the valve to divert water through the dhw heat exchanger,giving us hot water but no heating, if i refit the motor the problem comes back heating no dhw.ordered new motorised valve assembly £30 next day order .
this was a simple fix without having to drain the system down.

SOURCE: ariston genus premium 24 error
Code 101 is related to connection between pcb and boiler unit.check if the electrodes are still sparking even after the gas had lit, this means the pcb is not detecting the flame and trying to relight.Try reset,
If operation is blocked, the display shows the text RESET and the relevant error code. To restore boiler operation, simply press the RESET button on the control panel. If still the same error is coming up then turn the unit off for 1 hour then restart it again and check.If still the same error is coming up then press the "INFO TOP" button on the system .Simply by repeatedly pressing the "INFO TOP" button, the user may immediately view a whole range of information which is necessary to the correct operation of the boiler.---------If the reset is not helping and still the error is coming up again then the pcb has to be checked to resolve the problem.-----------Thanks.Helpmech.

It clearly indicated the problem is the programmer.The board does not accepts the settings.In old system or short circuit system this problem occurs.Solution is to replace the control board.
Please do rate the solution if the issue is resolved or post a comment for further assistance.
Thank you for using fixya have a nice day:-)
