central heating boiler blowing 3A fuses

[dazahara]

hi all

i have a glowworm 30cxi that is blowing the external 3A fuse!

i have opened it up to find the divertor valve motor is wet around 3 pin plug, obviously this will need changed but i am concerned how the water has managed to get to it?

can i change just the motor or is there a bigger problem causing this????

please help!!!

Changing the motor will be like treating the symptoms NOT the cause. it is clear that there is water leaking from somewhere, is the boiler primary circuit losing pressure and needing recharging at the filling loop regularly? if so have a good look around could be the diverter valve spindle leaking into the motor, if no pressure loss, have a good look at the left hand hydroblock these are domestic water side and have a habit of splitting causing a near invisible fine spray of water to soak whate ever gets in it's way

the system never looses pressure and the only water/moisture i have found was inside the divertor motor (which i have now stripped off and cleaned out) i have refitted this and had a hot shower lol.

i have also ordered a new motor online although this may only be a short term fix????????????

i did notice a small o-ring inside the motor and was kinda hoping that this was the problem because it looks like a nightmare to change the diversion valve itself?

thanks again for thou reply!
