So, as is usually the way, my boiler chose the most inconvenient time to break down- Easter weekend when expecting a houseful of guests! I have bodged a repair but just wondering if it is safe...
The problem is the diverted valve (glowworm betacom 24c) which appears to have been leaking into the valve motor causing it to fail in the CH position.
I cannot obtain a valve repair kit and replacement motor until after the weekend, so instead removed the motor, opened it up and manually rotated the internal wheel to the DHW position (centre stem fully extended to fully depress diverted valve)
I then clipped the motor back onto the diverter valve, which depressed the valve to DHW. I did not reattach the wires to the motor as I don't want it to switch, just stay on DHW. I suspect it is knackered anyway, I could hear water sloshing inside it...
So now I have hot water at least, but am slightly concerned that by essentially forcing the valve to remain permanently directing water to the DHW side I have overridden some kind of safety feature? Is there supposed to be any diverter valve bypass to CH under certain conditions (overheat perhaps) that is now no longer possible with the valve disconnected from the power? All seems to be operating perfectly, I just don't want to risk it if remotely dangerous!
Obviously the motor will be replaced asap and the leaking valve repaired but I really want to avoid huge call out fees if not strictly necessary. Any advice incredibly welcome!
