Baxi duo tec2 GA 40 flow sensor?

[jakeh83]

Hey guys/gals after some help been to a job fluctuating temps on shower, new blending valve changed as was passing, but boiler still won't stay on and kicks off after a minute of shower running, the hall sensor is flashing detecting flow but was wondering weather the dhw Ntc sensor could be faulty, P2P is clean and customer had cartridge changed on shower. Any help appreciated

Good starting point.

It could be the easiest and cheapest thing to change to see if it rectifies the problem.
Meaning: If you changed it and it didn't fix the problem, you wouldn't bother removing it and putting the old one back in.

How do you know p2p is clean?
Does the same happen on heating?
