Hi everyone,

I went to top up my Logic S15 boiler earlier as the pressure gauge was at zero. I’d done this before so I knew to expect to hear rushing water through the pipes when i turned the valve, but I heard nothing. I unscrewed the filling loop because i thought that might be the issue, but the filling loop was clear and it was the tap that wasn’t letting any water through. By now, I’d already moved some of the other valves and couldn’t work out what they’d looked like before, so I couldnt return them to their open/closed positions. Any way I turn the one connected to the cold pipe doesn’t allow water out, though.


I read online that there might be a leak causing the pipe to not let cold water through, but all the other taps in the house are letting water out at their maximum pressures — like normal, basically. I’m wondering if there’s something I’m missing or an easy fix for all of this before I call someone to help. I’ve attached some pictures here: https://imgur.com/a/48U3TlP


Thanks!!
 
The cold inlet isolation valve on some ideal boilers is a 3way ,off/cold water on / position for passing water to filling loop so would think yo have it in wrong position
 
It looks as though the flow and return valves (black handles) are closed? Also your gas isolation valve (yellow handle) looks closed.

Thank you, I’ll try to get it into a different position and see what happens

Thank you haha, I’ve turned them all in the opposite direction now
 
Sounds like the cold side might have failed, it has a double check valve inside, which may have failed, or the ball inside no longer turns. You can purchase new ones, and by the sounds of it, you sound capable enough to replace it.
