Worcester heatslave 15/19

Hi
Anyone worked on the worcester heatslave 15/19

Been on a breakdown today the boiler had locked out due to the isolation valve being closed from the oil tank.
the burner to come on but it was supplying a very low heat and the rads stayed cold and the hot water was luke warm and the boiler would not fire up fully for any demand called for.
Worcerter say it takes up to one n half hrs to heat the tank before burner will light fully but 2 hrs in and still nothing but low heat from burner.
Any ideas greatfull
Neil

not sure where your coming fm but my simple understanding is that your burner is at its normal firing rate or off, no in between on a pressure jet boiler, sounds like your talking about a boiler locking out due to an air lock in the fuel line that needs bleeding or the filters cleaning. If fuel supply is ok you may have knackered fuel pump with blown seals / gears if the poor thing has been running dry. tested your pump pressure is at correct levels? have a read of these for some help Heatslave CF 15/19 Combi (discontinued December 2007) literature - Worcester, Bosch Group UK installer site

What was the oil pressure when it was running?

These things are on or off.

seems theres a new pressure jet burner out there with a low/ high firing rate or someone is muddling gas and oil when chatting to WB techies

It certainly doesnt take an hour and a half to heat the store.

And a two stage burner would be bouncing back off the rear of the combustion chamber.
