Ideal isar m30100 problem - help!

[jle78cat]

My husband woke up ths morning to a cold shower! The boiler wasn't working.

When I inspected it (turned it back on, as he turned it off), the display was flashing L F

Looked at manual, pressed the reset button - seemed to start up OK, then became noisy and water started to pour out of the casing (not much, but steady thin stream from middle left hand side.

Could it be a blocked condensate pipe/trap? Been looking at these forums a while. My dad - ex CORGI, retired - is on his way to see if its simple or need to get someone out, but was hoping to give him a few ideas as he has been retired some fifteen years, and is not familiar with the boiler.

Any help welcomed!
Thanks

It certainly sounds like a blocked condensate outlet or possibly a blocked outlet from the sump at the base of the main heat exchanger.

This would be evidenced by no drop in system pressure when boiler is not on( as the pump adds pressure to the gauge on that model.

It sounds as if you have not had your boiler serviced every year as recommended!

How many people do?? But guilty as charged.

Having done a bit of reading of the manual, and a further inspection have discovered that whoever installed the condensate pipe did so coming down out of the boiler vertially and then fitted an L shaped joint and ran the pipe horizontally out of the wall of the house sticking 20cm out of the wall.
The recent -7C here seems to have resulted in a plug of frozen water!

Up a ladder with a hairdryer for an hour seems to have unblocked the ice somewhat - a steady drip is now coming out of it.

Could this have caused damage to anything else? Apart from all the water that seems to have built up inside, which is now being dried out before we try to start it up again?

Note to self - get boiler serviced

Pouring boiling water over the frozen pipe is usually more effective!

If you can disconect inside and pour boiling water down it once there is a little flow will rapidly sort it out.

Or pour boiling water down inner flue from outside!
