Grant Vortex oil boiler sensor replacement

[PThomas]

We have a 26e Grant boiler, this week it wouldn't fire up, the power light blinked slowly but never fully illuminated. Some googling and a call to Grant and we diagnosed a failed PCB.
Luckily a local plumbers merchant had one in stock, so I was able to replace it the same day - all working again

However, the new board comes with 2 new replacement sensors, white for the store sensor and black for the flow sensor.
I didn't want to change these at the same time, to check everything was working first. (Nothing worse than changing multiple things and not knowing what caused the issue, or even bigger issue if something else doesn't work after you introduced a new problem!)

Any advice on replacing these sensors? do they just push into their housing? Will the old ones be a pain to remove?

Simple answer don't bother we actually only change the sensors when we know they're not working.

@Exedon I belive the black Flow Thermistor is easy pull out & replace. what about the store Thermistor ?

If you want to create work crack on
I would add we have only ever changed 2 grant thermistors.
We look after over 300 grant combi's.
