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 Pro 28 F61 repair

This was a repair I did today on a first generation Vaillant ecotec Pro 28 Combi boiler in Barnsley, S71.

The fault was an intermittent F.61 fault, allowing the boiler to be reset each time. Often is the case with these models that the printed circuit board starts to fail and presents the F.61 fault code.

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.
