Had a customer complain of no hot water / heating with their 6 month old Ecotec plus 837. I popped over and had a look, seized pump, stripped it out and it was sticking. The water quality (to me) was ok, no bits in the casing, the TF1 was cleaned and had a caught a little sludge but nothing much. I told the customer to contact Vaillant and arrange for an engineer to call out and change the pump.
He went out and changed the pump and then said to my customer that there was too much cleaner in the water and it needed flushed out!.
The customer has phoned me this morning telling me this so now I have to go out and see what the issue is with the system water. It was flushed when I installed the boiler and I find it strange that there would be cleaner in the system when it was drained and refilled and dosed with inhibitor. This is the first time I have had to get a warranty visit, has anyone ever heard of too much cleaner/inhibitor in a system as a cause of seizing a 6 month old boiler pump? or is it just Vaillant trying to cover up something?
