ferrolli modena 102 cutting out on hot water...

[jamhot]

when opening the hot tap the boiler fires up ok then after 10 seconds it cuts out

When the case that coveres the combustoin chamber fan etc is taken off the boiler seems to work fine. hot water fires up to right temp and stays on...

I checked the two hoses that come off the fan to see if they were blocked. clear

--

I have a feeling its something to do with air intake? a problem with the fan..maybee? any one come across this before?

cheers

Is it doint this on heating??

Please be careful as your opening a sealed unit

 

[jamhot]

no heating is fine...

only happens on hot water!

You really should get a registered installer to look @ it buddy !!

I get the impression this is way beyond DIY

 

[jamhot]

I am registered lol.

I tried the helpline on ferrolli but they wasnt answering..

Iv a feeling its a venturi on the fan. wanted a 2nd opinion

I was gonna say check the flue aint leaking.. yeah could be venturi

i am sure iv heard that venturi on modenas were prone to nakkering up..ended up crumbling.

try the combustion chamber for more detailed "ripping boilers apart" info, especially gas/safety bits

if venturi is red it requires changing to white/brown also wromg size restrictor ring above fan can also be problematic dont attempt if you are unskilled inthis area of work
