definately, As i said above i came home and stuck the exact same gauge into my own pump and it was reading no sweat. I know it doesnt really make any sense. Was thinking that maybe a tigerloop might have been fitted at some stage and the wee grub screw you put in might have re...

Hi Tony, I was thinking that myself but on teh side of the pump you a test point that says P and the test point below it says V and these usually signify your pressure and vacuum test points?? I was on the Danfoss website last night trying to get the tech spec for the pump but couldnt...

Alright guys, Was just out an annual service on a Nuway Boxer Oil Burner and there and was going through the regular checks. Burner seems to be working away merrily. The pump type on the burner was Danfoss Type BFP 31L and when i screwed my pressure guage into the port labelled P on the...

I hear what you are saying but the nozzle isnt a year old yet??? I have seen some nozzle totally blocked up and still burning sweet. This one still looks brand new. Take on board you cant tell by looking at it. Before i started servciing myself i had a Sterling burner, which i think...

I serviced the boiler myself about 8 mths and i checked the nozzle as well and it is all clear.

Hi guys, Was just out a job there where the boiler flue is churning out black soot and blackening the wall. The burner is a 1992 Bentone Electro Oil (serial No 031201000010039 (unless info!!). Has a danfoss pump fitted and a riello Capacitor!!! I was recently called out to bleed this...

I take it is a nightmare then???? The insturtions in the manual made it sound like a gift!!! Just take out a couple of clips and away you go. I will go back tommorrow and gently persuade it to work!!!! Grill

Update gentlemen, Went back to the job tonight armed with a new PCB. The discovered that the 230 V terminal wasn't plugged into the existing board and hence the lights came on on the dash. Still no heat or hot water. So i checked both flow switch (had to screw them out as there was...

Hi again guys, Went back to this boiler again tonight to check the DHW flow switch and found that i was getting no lights at all on the front panel!!!! I checked i had 240 V in okay and checked the two fuses on the board which were both fine. I then checked to see was i getting 240 V to...

Ah right thats makes sense then. I was wondering about that!!!!! Have any of you guys got any idea about this digital clock??? Grill

Hi ya, Im looking at the MIs for the Calydra Comfort and on the instructions for changing the DHW flow switch it says DHW Flow Switch - Disconnect the electrical connections, undo the securing clip, and remove the micro switch reassemble in reverse order That is our of the Maintenace...

Ah ha i see what you mean now!!!!! If it is the switch then how do you go about changing it?? In the MIs it just says "Disconnect electrical connection, undo clip and remove microswitch". Doesnt say anything about draining down the DHW circuit!!! Is it possible to have a dry flow...

Hi Scatmanjohn, What exactly do you mean by "Chaff calydra YUK." Is the flow switch a common fault then. Im reading through the manual here and it telling me that there is a series of flashing lights for faults. Are these boilers easy to work on???? Cheers Grill

Hi All, Was called out to a Chaffoteaux et Maury Calydra Comfort 100 today which has heat working but no DHW. I took the MI,s with me but when i got there the clock is a digital one and not mechanical as per the MI,s. Anyway i couldn't even work out how to get the heat on so i had to...

Problem solved, The guy had dislodged the control box when he was messing about with the pump. Fixed it back in place, Set up the pump correctly and away she went. Thanks again Grill

The pressure in the danfoss oil pump. This adjustable and should read about 8 bar. He messed about with the pressure adjustment when he was trying to bleed the burner so this will need to be setup properly again. grill

Do you think it might be down to him messing about with the pump pressure??? I will set it up properly and set it to 8 bar. Will ahve to do a few more checks as well obviously. Grill

Evening people, Got a phone call from my mate to say he had run out of oil and asking how does he bleed his Sterling boiler (Danfoss pump). So i explained to him how to do it. Got the oil through but he failed to mention to me that he had messed about with pressure adjustment screw as well...
