The MV's seem (from memory) to have closed. I've not had chance to check the continuity (unfortunately I work as a desk monkey but checking that is one of the jobs on my list this eve!)
Yeah i've been reading about the solo 2's and the PCB seems to control the pump over run which according to the manwell is based on a timing chip of about 8-10 mins... The boilers 10 years old so i'm thinking the PCB could have a dry joint or the timing chip's fekked! However not being GSR etc and not wanting to take any risks a man who can and is qualified is needed for that!
I've run the pump slow and fast (I was told to put it on fast to aid the overheat problem!), the pump itself isn't unsually noisy (I have heard some air come through it when the boilers going) its more the fact its constantly on whirring away!
