Hi All.
I have a Worcester Highflow 3.5 Gas boiler which seems to have developed a fault and I thought I would ask you guys for some advice.
I will not be attempting any major repairs myself (simple stuff I can do i.e. resetting things, testing and so on), I will leave that to the experts. But I would like to hear you opinions even if its just so i can prepare myself for the shock of the likley final bill.
The problem is this....We normally leave the hot water on all the time and the heating on the timer twice a day.
Now when i turn on the hot water, the radiators get very hot very quickly, whilst the hot water does not heat up beyond tepid or hand warm, then goes cold. Meanwhile, the rads get hotter and hotter.
Also, because my gas meter is in view of the bioler, I can see that the meter is whirring away at full belt, as if a hot water tap or the shower was on.
All of this is happening whilst the heating is in the OFF position...!
So with the water on and the heating off, I can heat the house till the rads are bouncing but with no hot water.
Next, i tried turning the water OFF and the heating ON....
In this case, the rads again get hot and i notice that the hot water light is showing that the DHW is ON as well as the CH even though the DHW switch is showing OFF !. I also notice that the gas is being used at a much reduced rate.
Again, I can get a sinkfull of hot water and thats all but the heating is working overtime. At least now though, the boiler switches the heating on and off according to the setting of the CH temp setting dial (as long as i set the HW dial to off) thus regulating the temp.
I can get the temp and the preassure to stabalise at around 2.5 bar by setting the DHW to off and the CH to just below position one on the dial. At this setting the rads are hot (hotter than they should be at this temp) and the preassure shows around 2.5 bar....if i turn either of the dials higher then the temp goes through the roof along with the preassure.
I wondered if I have a broken/stuck 3 way valve ? and is there a way to free it or a reset procedure I can try ?
Many Thanks
Shaun
