Hi All

My old faithfall (had 7 years) Ferroli Optima 601 is starting to play up. I am unable to get hot water from the hot taps, flow is fine but water remains cold. This is intermittent but getting worse over time. I also noticed that the taps further from the boiler are more off a problem ?

I have checked the boiler with the hot tap on full flow and the main burner is not igniting, if i give the boiler cassing a little 'nudge' i can hear an audible 'click' and the boiler ignites perfectly....

The Heaing is fine and comes on straight away from remote thermostat.

Any ideas what this could be peeps ? Is it anything todo with the recent cold weater ??

Any help here much appreciated as it's getting frustrating going to the boiler each time for DHW.

Thanks

Sounds like a failing diverter valve.

I am not sure what a 601 is as we usually see 701s !

I know that 501s are jeans though!

Would this effect the burner igniting. Run HW tap and burner is still off. Give boiler a 'bang' on front and it ignites.

By me nudging it am i i freeing off the divertor valve (i know it has one), which in turns is making some microswitch (the click i can hear) which in turn ignites the boiler ?

Cheers

Why when i give it a 'bang' on the boiler casing does the main burner ignite. This is the case for HW and CH.

I must be releasing something ??

UPDATE - This is getting even worse now. I have been fiddling with boiler and turned gas supply off and extinguished pilot light BUT cannot relight it.

Pump is running, allsettings set to max etc but there is no spark whatsoever, not even clicking noise.....

Anyone help me here ??? On the coldest night of winter as well....!!!!

One might ask just why you were fiddling and turning off the gas supply!
