Fuse blowing with boiler & programmer working for a whi - Central Heating job in Purley, Surrey

Job description

I have a very old but reliable Ideal Standard E Type RS60/80 boiler that is generally very reliable and a Sunvic Select programmer. The boiler is a cast iron boiler from the 1970s.

The whole system works perfectly for a while and then blows the main fuse which I have changed several times from initially a 3 amp fuse to a 5 amp fuse. The 5 amp fuse works a bit longer but still blows. I need an engineer who is good at fault finding

Feedback for Ignis Installations

Mark from Ignis Installations arrived and diagnosed the fault with my boiler system where fuses kept blowing. He bypassed the programmer and got the boiler working and informed me that I need a new programmer. He specified a programmer which was a direct replacement and informed me that I could buy and replace it if I so wished in order to save money or he would do the work himself. I decided to purchase and fit one myself which I have done and the system is now working perfectly. So far no fuses have blown.
I would use Mark again as he was very friendly and helpful and appeared to be very good at fault finding.
