Grant Vortex Combi Boiler Runs Intermittently


I have installed a Grant Vortex Combi boiler one year ago. I have faced some minor issues in the past but the problem, which I am facing now days, is quite irritating. The boiler runs intermittently. Due to this, the taps and the radiators are becoming hot & cold continuously. I have tried to fix the problem but no progress. Someone please help me

Thank you so much


Hi Wendy,

The main culprits behind your boiler runs intermittently are the faulty control panel and printed circuit board. Well, you cannot fix the problem alone. Therefore, I would advise calling an experienced Grant boiler engineer, as he will decide that whether a PCB is having the needed power supply or not by using the multimeter.
