Position markers A and B are shown only on the Drayton DV controller unit. Note that the "brass body" has a right way up, and a wrong one. It is the right way up in the photo. In the photo of the DV 'brass body' in position (with the controller off for clarity), there are three connections ...

You are not giving me and Steve much credit yet! Here is a picture of the Diverter valve we took out. Let me know if you would like to see a photo of it dismantled. I cleaned it up, refurbished as required, and reassembled it using the correct lube. Now it is a 'good as new spare'. But, in the...

The valve is the usual "right way round". The manual tells us the make and model is Worcester Bosch Group GREENSTAR HEATSLAVE EXTERNAL 25/32 Floor standing external oil fired condensing combination boiler using balanced flue system. It was installed in October 2013, and has run faultlessly...

I can't see a way to take your valve pic out, so my apologies for repeating it. Here's a pic of my Drayton, right side of controller body, indicator peg again clearly at rest at Position A, which is (in my boiler at least) the default resting position which is for DHW. Position B is for...

No, there is not. Definitely NOT.

Chris, That is NOT my model of DV valve. My one is a competely different make, model and fittings. Mine is a DRAYTON "Hansen Class 'F'" DIVERTER VALVE 27904 8-718-684-238 and I have it IN MY HAND. Position A is the default rest position and is the DHW position FOR CERTAIN. Position B is CH...

Thanks Hairymelon. Almost certainly NOT. What happens when I open a DHW hot tap depends on the flow switch working. However, I will check it at the first opportunity. That is quite easy to do. For example : 1. the CH has been working all today, but crucially I HAVE NOT RUN ANY DHW ALL DAY...

Meldrewsmate, It is a kerosene external boiler, sealed system. You point out "I am not familiar with this boiler". It seems clear to us there is a specific problem, and it is clear to us so far that the usual fixes aren't dealing with it. This is going to need a really expert Heatslave 26/32...

Many thanks. That was kind. I'm only 79, so I am not well up on how these forums work. My CH has been running non-stop all day, and will be till I turn the electric blanket to full turbo-boost, and go to my bed ! Before I turn in I will set the ROOM STAT to about 20°C. The CH will stop right...

ADDENDUM. I should have said that the DHW is working just as it should, night and day. My apologies for struggling to find my way around the forum. Just put it down to old age. Charles

FAO IANMCD please. Ian, As someone with 70-years reputation for fixing just about anything, including professionally to this day, it's a bitter blow that I can't fix my own boiler, and neither so far has my plumber / heating engineer Steve been able to, though he did do some good diagnosis, and...
