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.

Leaking Magnaclean magnetic system filter

This was the 2nd of my 6 jobs that I did on this Friday for a customer who lives in Barnsley, S72. This repair wasn’t anything major, actually quite a trivial problem.

These type of filters have an O ring seal at the top which can leak. On the lid it does stipulate that the lid should only be hand tightened, but often they get over tightened. There is a tool to remove the lid sometimes it is used to tighten the lid as well.

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.

Vaillant ecoMAX Pro 28 E service

This was an annual service of a Vaillant ecoMAX Pro 28 E heat only boiler, in Mosborough, Sheffield, S12.

I don’t come across many of these boilers in the area I work in to be honest. Most of them I come across are branded as Glowworm hxi boilers which is almost identical to the ecoMAX Pro. The ecoTEC Plus 400 Series which supersedes the ecoMAX Pro is also very similar.

Vaillant TURBOmax Plus 828E Repair

This was another Vaillant TURBOmax Plus 828E I worked on this week, this one being a repair of a faulty printed circuit board. this was a job for a customer of mine who lives in S70, Barnsley, South Yorkshire.

This boiler is installed in a fairly large house and the customer actually has 3 of them which service various parts of the house.
