Have affected solution for last 12 months by replacing the main PCB.
Went for brand new rather than exchange unit from North London outlet, as they didn't have any stock of old boards to repair (so cost me over £300!)
However, now boiler seems to be on the blink again, (no HW whilst CH is...
Yep, CH is doing everything it ever did. Turn up the thermostat and the boiler fires up and rads get hot.
HW, turn on and nothing happens. Not a click, a whirrr, zip!
Hence my Question about the flow sensor and diverter valve.
Could all be academic if I cant get any spares though?
My son has now found a valve to top up the pressure and were back on to 1.5 bar, but still no HW.
So any thoughts on the Flow Sensor or, as somebody has mentioned, a HW/CH diverter valve solenoid / motor??
I'm still trying to source spares and loved the coment from one of the other forums...
Thanks Dave,
Its actually got three pressure lights that double up with a few more as temp indicatiors.
I'm not clear on how to re-pressurise when the system seems to be permenantly linked to the mains (no valves along the mainfold except for the yellow Gas Supply)
Cheers C..
Hi Guys,
We've got Radiant slimline 24 that has been working fine, but suddenly refuses to heat the hot water. Central heating is fine.
Pressure is at 0.5 bar and manual says set at 1.5 initally, but the system seems to be hard plumbed into the water mains. Can't find any input filters, so...
