Worcester 28i JUNIOR combi, No Lights 🚥❌, No Power 😵, Fault Finding and Repair 🤓 

you cant go wrong with a video like this, very detailed, thank you.

Most best is your explanation

A-MA-ZING absolutely perfect just what i needed. Just need to watch your other vid on multi-meters, but i have one question, which way round does the transformer go? as i 'feel' it can go back on (new one I've ordered) in 2 different ways it will slot in place!! a plumber told me it will only go back one way but i think i could re-fit it 2 ways so might cause more damage. alas when i removed it i had a problem (wont tell you what that was!) so i was distracted so didnt notice its orientation

What an educating video, it saves my day Bravo

Great video mate 👍

Once again perfectly explained nice and simple thanks as always

Thank you that was very helpful hopefully this will help going forward

A good sign of the transformer blown is the smell it gives off. I strip old boilers and have a large stock of parts which saves the customer a new boiler or expensive parts.

You could also do a short circuit test at the board to the fan gas valve pump etc

Brilliant vid

This happened to me . Worcester said needed new board and transformer. Got reconditioned one for £6 . Saved my customer a fortune

Nice explanation.

Top man thank you , I got same problem 😊

Good video Phaji

Hi mate, which areas you cover?

Happens a lot on the Ri could have saved your fuses I always look at that first on them strongly it never normally damages the pcb I just change the transformer
