Condensate baking up is the no. 1 cause of F1 faults on these. Anyone else noticed the amount of crap that gets in the condensate trap seems worse on the hxi's than most? Plus the condensate trap, siphon adaptor, float soon stops working and seems a poorer than usual bit of the art of...

For anyone who might be interested I got this reply after contacting the manufacturers tech support. ******* Thank you for your enquiry. The correct nominal voltage reading is 36V dc red to blue. Martyn D Buckley Technical Support Manager *******

Trouble with this is I know of an accident because the RCD fed both sockets and lighting in a garage. Someone using a disc-cutter was suddenly plunged into total darkness when the RCD tripped of couse the tool was still rotating at near operating speed - you need little imagination about the...

Yes looks like brushless dc motor, the voltage is applied to it all the time. Then Hall effect ic on the motor board will pulse probably twice per revolution and the speed controlled by PWM from the panel in the boiler - similar principle to bigger machines I am more used to. Will give them a...

Yes there were / are small clips on the impellor blades and a mark where one had fell off.

Yes thanks for that - it all makes sense to my gas fitting oppo, I don't mess with the gas side of things my area is electrical - and why I got involved here. It is quite definitely a mechanical / balance problem on the old unit we are not bothered about that. The service call was to fix a...

The vibration is not constant, (looking at the impeller and spinning it by hand it is quite obvious that a balance wieght or something has dropped off at some time). At low speed is more pronounced than when running at high speed but there is still some there, I guess it is the frequency of the...

Need some help from someone who is familiar with these boilers. The fan in this developed out-of-balance problems resulting in very noisy operation and vibration. This was replaced with a new fan which lasted for about 5 hours and then stopped. The voltage from the fan transformer on...
