Hi, before I start I've read a vast amount of posts about this boiler now and realise it's problematic to say the least. We had ours fitted 2008 by warmsure. Shortly after we had a problem and the orange board was replaced, this also turned out to be faulty and was changed again within a week. We took out a policy with home serve to cover it and have had an engineer out at least once a yr plus yearly service. This year already we've had an engineer out about 4 or 5 times with a recurring problem; loosing pressure, boiler cutting out, shower alternating between cold and warm. Parts were replaced each visit plus had to pay engineer £40 for inhibitor in May as he drained system! Next I discovered a leak which was blamed on a loose nut, after he left found another leak engineer said it was a hairline crack. Original engineer was sent, said he couldn't see crack but changed the part anyway plus performed a service and refused to refill inhibitor free of charge after he drained system again. That was last week and couple days later shower is still going cold and then today it showed an error message L E. Is it possible something is being overlooked? I complained to Homeserve, they asked engineers to resolve it, they passed it back to homeserve, any suggestions?
