Halstead 102 combi boiler, hot water sometimes cuts out when running a bath or shower any suggestions?

The most likely culprit is the primary sensor.


Does the boiler not display any fault codes or flashing lights.


If the boiler has a divertor valve then the diaphragm might be stretched and needing replaced.


Can only offer an educated guess.Halstead 102 combi boiler, hot water sometimes cuts out when running a bath or shower any suggestions?
I am assuming you are in the UK, and that you are using this for both heat and hot water?





Typically, this is caused by a faulty flow-switch/diverter valve. This valve may be sticking due to sludge or age. Could also be the secondary (domestic water) heat exchanger is clogged.





Get it serviced. Demand-type water heaters should only be touched by competent and qualified technicians.
