halstead eden cbx 32 problem

[andydoo]

Hi
have a halstead cbx 32 combi. installed 2006. CH working fine DHW will work only if I turn off the CH and reset the boiler, then I have no CH untill a further reset of boiler. 1 engineer said nothing is wrong? 2nd engineer never turned up! please help (what could this be?)

most likely the flow switch is no good, they fail regularly on these boilers

many thanks, is this something I can replace myself?

fairly easy to do. turn off the water first though!! and put fresh fibre washers either side.

when you say you have to reset the boiler do you get a red light? if so hold the button in for 3 seconds and it will give you a fault code via the 4 small lights.then check the code on the lower case flap.If the boiler is locking out (showing red)its unlikely to be the flow switch

I know this is an old post but I'm having same problems, did you solve it? Any one any ideas, no fault codes or red led but same problem as above. Thanks in advance

Probably the same solution then...

Looking at the manual, the flow switches look clip on type, what did the post mean about putting fibre washers on aswell, cheers for replying.

Just a follow up , it was the diverter valve motor head. Very expensive repair!!

I expect the motors are only about £30 to buy and should have been about £84 to diagnose the fault!

Thats surely not very expensive!

Replacement motor was £159, labour from gas engineer was £60. Checked price on line, could have got it few pounds cheaper but would have to wait for it. Halstead parts very expensive since Dimplex took them over. Engineer advised me to keep the old one & get it repaired for future use as they tend to go quite a lot.
