Discuss How does a boiler sense the condensate pipe is blocked? in the Central Heating Forum area at PlumbersForums.net
Thanks oz-plumber, I did wonder if perhaps sensor failure could cause the same effect (boiler shutdown/lockout)There are sensors in the heat exchanger that are specific to this fault.
They detect the condensate level in the heat exchanger and hence attribute the fault to condensate blockage.
Mind you - 30% of the faults are caused by faulty sensors!!!
Worcester Bosch Greenstar 18Ri.What boiler are we talking about?

they work on fan pressure
What does? Are you saying an increase in fan pressure correlates to a blocked discharge? That would make sense
how the boiler senses the condy is blocked water will rise back into the hex blocking the flue so the ap switch senses this which in turn turns the boiler off / fault
Don’t under any circumstances attempt to by pass the sensor.
To avoid such intervention, most boiler control logic sequences will initially test the APS to be open before fan start up, only firing once the fan has started and subsequently proved the APS closed.
Never override or attempt to override a safety control sequence.
In my business it is a summary dismissal offence.
