Flexicom 30CX F09 error every night

[abrahamlove]

Morning. We have an 18 month old Flexicom 30CX. Will work fine during the day, then overnight (during cold weather) the boiler generates an F09 fault and will not come on on timer in the morning. Overnight heating is set to keep house about 16 degrees, but it drops below that - come morning no h/w or heating. Sometimes a button reset will fix it. But mostly I have to (once or twice) turn off at the mains and turn on again to get it working. Like I say - seems to have only happened since the cold weather.

Pressure doesn't change. It is at 1.7 all the time.

Any ideas?

Thanks.

Hi - Abrahamlove. Just read your post - I know it's nearly 2 years ago, but we are having the same symptoms with a Flexicom 30cx. Do you remember what the problem was - what did you have to do???? It's driving us mad.
