Vaillant Ecotec + 837 Boiler F75 No Central Heating Or Hot Water

By Futli @futlim

Boiler was at Tavistock Road, Edgware. Client didnt have hotwater or heating for nearly a week. Other Engineers came but could not repair. It was clear according to the boiler Manufacture F75= Error, pump water shortage , and the cause = Water pressure sensor / pump defective, air in heating system, too little water in the boiler. And the solution = Check adjustable by pass, connect external expansion vessel to return. I am not convinced…What if the Boiler is lying because of a faulty PCB. Anyway I am not goin to tell you which part was actually faulty. I repaired the boiler and this nice family got their Hot water & heating back before the Xmas evening. God Bless! Hear is customer testimonial ” Professional, reliable, competitively priced company. The engineer ( Nish) was polite, accessible, responsive and went out of his way to complete the repair. Definitely recommend him. Thanks again.” Mr & Mrs Deva – Travistock Road, Edgware HA8 ( 10.02.2011)
