Hello Janman. This isn't an answer to your question, it's more a question for you. I have the same kind of boiler and I'm having the exact same problem. I was just wondering if you had managed to fix it ?? I was told it was the thermostat that was broken and the guy that was supposed to be fixing it hasn't got back to me yet. can you help at all ??
Thanks in advance
