Vaillant ecotec plus 831 pump replacement

This was a repair on a Vaillant ecotec Plus 831 in Sheffield, S11. The pump was still working but was failing and was making a rumbling noise at certain speeds.

On these models the pump can vary its speed depending on the load on the system. As such I have found that often they may run quietly until they run at a certain speed at which point they can be quite loud.

Vaillant ecotec F.75 repair

This was a repair I did on a Vaillant ecotec pro which had stopped working altogether. The display was showing the dreaded, yet extremely common F.75 fault code. The early versions of the ecotec boilers were fitted with problematic pumps and early versions of the pressure sensors also suffered from issues.

Vaillant ecotec Plus 937 hot water repair

This was a repair I did this week on Wednesday, on a Vaillant ecotec Plus 937, in Norton, Sheffield, S11, South Yorkshire. The issue was with the hot water not working properly.

I can typically repair hot water issues with the 937 within one visit. I carry plenty of spares these models including the expensive actoSTOR pump that you will read about.

Vaillant ecoTEC PLUS 418 service

This was a standard annual service of a Vaillant ecoTEC PLUS heat-only boiler in Ecclesfield, Sheffield S5, done in August 2018.

I started looking after this boiler back in 2015 a year after it had been installed.

This customer has had me back each year for its annual service. So far it has been a reliable boiler with no issues.
