Our Camray 2 boiler ran dry and some of the "crud" from the bottom of the tank has got into it (it's happened before) but we have no idea where the filter that requires cleaning is as we inherited it with no manual!

if the oil line is blocked turn off at tank disconnect then disconnect oil line at boiler use a bike pump to push any crap back through the oil line this is the cheapest way if it works good luck ive done it before lots of times

YOUR SHOULD HAVE A FILTER ON THE OIL TANK / OR INLINE ON THE OIL LINE.
1. CLEAN THE FILTERS
2. BLEED OIL PUMP
3. TRY TO FIRE THE BOILER
4 IF IT GO'S INTO LOCK OUT RESET ONE MORE TIME
5 IF NO GOOD CHANGE OIL NOZZLE AND RESTET LOCK OUT
6 I BLEAVE THAT CAMRAY IS MADE BY WORCESTER YOU CAN DOWN LOAD MANUALS
