Hi, I have a fault with my Ariston A23/MFFI Microcombi.
I've had to replace a faulty Air Pressure Switch 3 weeks ago. Since then a different fault has developed where the boiler switches on but trips out after 2/3 seconds, then restarts and trips out again after 2/3 seconds. This goes on as long as the boiler is switched on.
The boiler is heating the radiators and the water but i need to solve this constant switching on/off problem.
The PCB has been checked by a pro and is working ok, but they haven't ben able to diagnose the problem.
The boiler is less than 2 years old but out of guarantee.
Any suggestions welcome!
Thanks.
