Hi all,
I´ve had an intermittent low pressure light problem for the last years or so, say every six months or so the light will come on (then no hot water or CH ), I will top up the pressure with the tap on the side, then it takes about a day and a half for the light to go out and it all works ok again for 6 months ish.
I am guessing that my pressure switch is getting stuck after a low pressure warning which would explain the day and a half for it to right itself and the low pressure light to go off and then all is ok.
I read on this forum that I can disconnect this from the PCB to get things working again, and also to see if it really is this switch causing the prob - can you check the picture below and tell me if this is the correct plug to unplug from the PCB (according to this old post here its the one with the 2 yeloow wires- //www.diynot.com/forums/viewtopic.php?t=17314- this should be the one):
Not the best picture but you can see I have pulled forward the front panel with the switches on and you can see the bottom left of the PCB.
I now also have a second problem which I may have caused myself. Having over pressurized the system I used the red tap thing inside the boiler on the right (picture below) to drain some water out of the overflow pipe that goes outside of the house to the drain:
This now drips constantly and the pressure slowly drop over the course of about 2 hours ish from 1 bar to 0.5 bar.
If I have the correct plug (with the yellow wires, pic 1 above) to disconnect the low pressure thing and can get my boiler providing hot water again, that would be a start. I can then deal with getting a new part for that.
I believe it also looks like I will need a new part that is now leaking (picture 2), but can counter that temporarily by adding more pressure when needed just so we can shower!!
So, all I need to know is, if I unplug that plug with 2 yellow wires from the PCB, will my low pressure light go off (as the pressure is ok when I top it up)?
