electramate 2000 12kw, nightmare!

Post  southern nrg on Tue Dec 06, 2011 3:54 pm

i'm a pretty competent engineer (not good looking pretty), got a call out to the above mentioned boiler which i have repaired in the past, the problems where, earth fault to heater (element broken), heater pump fault, various leaks! poxy thing. ok changed the leaking / broken heater, the heater circ pump, pcb. heater circ pump not working still, boiler is cold and all the sensor readings are low, so i assume they work ok, im not getting any voltage between a1 - a2 of relays t2, t3,t4, think that is right as the manual which i have got in front of me is totally different wiring config. spoke to gledhill before i changed heater, pcb and pump , they didnt have a clue???? they also recommended i put an mip068 retro fit kit in to replace the relays? they sent with this retro kit a 9kw boiler wiring diagram and said it was the same for the 12kw??? the 12kw has 3 elements the 9kw has 2 elements so really struggling to work this out, i think when the heater or pump went it has also taken out a relay or two, also what i think are the relays are made by hagar, which from previous experience are really s*** on the consumer unit side of things. the rest of the relays / contactors are schneder. anyone have any idea? it would be much appreciated.
Tght lines.

It should come with all the info you need.
Pictures and words!
If not try South Coast Green Energies.

They may help you.
Or call Gledhill spares and ask them to email them.

got one off gledhill, who are sending it with yet more spares!!! one of the incoming 63amp contactors has started to melt probably due to either the fault with the heater? or a loose contact, have you had any experience with these melting? this is literally the second of these electramates i have worked on. have you ever replaced an electramate if so what with? by the way ordered the part last thursday spoke to gledhill today and at first they told me it was posted thursday, then rang me about 2 hrs later to tell me they are waiting for a part and not sent my order, very angry customers! thanks gledhill for letting me know when i ordered them!
