Baxi Solo 2 - No Power To Pump

[waz125]

Seen several related posts to this but not my specific problem.

Tripped the ring main RCD last night - after resetting, couldn't operate the boiler for HW/CH. Eventually traced the problem to the circulating pump (won't operate). Tested all the feeds into/out of the controller and boiler and all OK except the feed for the pump. There is no power getting to the pump. Disconnected the pump wiring and now controlling it manually with a plug and the boiler is working just fine (so long as I remember to turn on the pump before turning on the boiler).

I think that there is a fuse on the PCB which may have blown (and which probably tripped the RCD in the first place) but before I go and strip the unit down, can somebody confirm this for me.

Thanks

as far as recall there is not a pump specific fuse fitted
and the act of a fuse "blowing" will not trip an RCD anyway, usually its the cause of a fuse blowing that also trips the RCD

you probably have a faulty over run timer

OK - Thanks. If the over-run timer is faulty, will this stop the pump dead in its tracks?

yes, or make it run continously it depends how it has failed
it also depends on which model of baxi solo 2 you have as I think some models have seperate overrun modules and some have the overrun incorperated on the main PCB (I may be wrong about this but someone will clarify)
