How to test the voltage on a Hall Effect sensor (float switch/bobbin type) 

Cheers Rob great info. So in effect the it's just a hall effect flip flop switch.

Fantastic video again mate, well done!!!! Jazz from igasplumb

Hi Rob, a thousand salutations, really awesome video, thanks so much.

Cheers Rob.. Informative as always

Finding these Baxi videos a great help to me as I’ve only recently delved into fault finding and repairs. Do you do any on sequence of operation?

These videos are very good, love the positivity 👍🏻

Loving these video's mate keep safe

Great video Rob your a star

Great video thanks once again

Excellent, thanks for that

👊 Nice !

First thank you for these videos they are very informative. A question from lowly homeowner. I have an old boiler (mascot ht330) which I think is the same as BAXI. If the boiler does not fire when the hot tap is on. But I can place a magnet on top of the hall sensor and trick the boiler into turning on. And I ran the descaling solution through so I think the boiler as clean as I can make now, but the issue is still there. Should try to replace the hall sensor or the mechanical bobber inside? How can I determine if the hall sensor is bad? I presume if I can get the boiler to turn on with a magnet its more likely that the bober assembly needs to be replaced or cleaned. Maybe you have a training on fixing the bober assembly? Again thank you for these videos.

Hi Rob could you please show us how to change a fan on the old Potterton Prima F 60F heat only boiler please. Thanks

Where can I get the magnetic strap for my multimeter? So handy

How do you check the condensate level switch on a combi boiler. I have one that seems to be sticking and wont switch on as condensate water rises. Untill the high water sensor powers the boiler off.
