Hi my mother has a 30 year old worcester danesmoor 15/19 the problems started about a year ago, first the old tranny had melted so i went to replace it only to discover (not a shock really) it was an updated model so on went the new tranny and leads all was fine for about 3 months.
next to go was the pump, again this was replaced with a new version, solenoid and adpater.
which brings me on to this week from hell.it broke down again.
all operation was fine i.e pump vented, plenty oil in tank, fan runs, drive dog fine, sparks away - but no oil.
i checked for 240v on the solenoid lead and i get nothing, whipped off the solenoid and power up, stick a screwdriver through it and it doesnt magnetize.
so come to the conclusion it's the relay box. only to find they dont sell bho11.1 box anymore. should be replaced with bho64 series again cant get it. finally settled with bho 72.10 and adapter plate.
tried the new box and plate on everything worked (oil going through to injector) but no spark!!! so examined the wiring diagram and discovered there was no power going to tranny, so i swapped terminal 7 for 6 on the adapter plate and now it all works fine -------for about a minute.
boiler goes through a purge then lights, flame is established then after a minute goes to lockout. does anyone know what i do now, my poor mum has never heard me swear so much in all my life. cheers in advance
