How can I fix my Ferroli Modena 102?My 2 year old Ferroli Modena 102 Boiler was working brilliantly just until about a month ago. Whenever the hot water is turned on in kitchen or shower the hot water is only running for 2 to 3 minutes, it then becomes cold for about a minute, and then it heats again, and this pattern of hot then cold gets repeated again and again whilst the water is running.
Could someone please advise which part would need changing and how to do it.
Thanks

i think mike is right, so try it rod and its simple, otherwise it cost an arm and a leg for engineers to come out with 5 diffrent parts that you end up paying a fortune for.

to check this you need to locate the two thermistors one is on the flow pipe ( far left ) and the other on the hot water pipe ( the one beside the flow ) these sensors are inside the boiler so remove thye case and trace the pipe up over till you find them. one will have green wires and the other red these are push on connectors swap the leads over and the water stays hot it is the hot water temperature sensor ( 99 % definate anyway but better still to test ( do not leave boiler run like this permantly or temrerarily as will damage boiler

hi,
sorry sounds like one for a boiler engineer; could be temperature sensor, gas valve modulator, circuit board, scaled up heat-exchanger, air pressure switch, etc... too hard to tell without being there
