Good idea.
Can't believe this guy joe
[code:1]says -
I simply gave another possible option - do you have a problem with that? [/code:1]
because Joe for the umpteenth time, you couldn't even describe the flow switch you were fumbling over because you don't know this boiler, or boilers generally. You described two impossible flow switch problems which can't exist here. When you heard another flowswitch mentioned, which is nothing to do with the problem you thought you knew about, you jumped on that as a possibility. Yes it is - so what, so is the pcb, temp sensor connections, loose wires, all sorts.
I've had a couple of dozen of this model boiler in bits, I daresay that's a couple of hundred between all of us. Have you ever seen one?
You are not "giving another possible option". A flow switch (not one you'd heard of) and other standard possibilities are in the mrfs intructions, which you certainly hadn't read when you started your ignorant interjections based on some different problem you heard of on a different boiler with different bits - they are not all the same.
You're just an ignoramus gobbing off, which everyone is fed up with.
Why don't you go on a medical forum and start being an ar5eh*le there - you must have had a pain once which you can tell people about a dozen or so times. Bound to be someone there who's got a pain. They will also complain about you, when you say that they might have what you had.
Please go away.
