MEVETMEVET Member Posts: 3
my Trinity 150 NTI Boiler is messing up every time we run hot water IE for showers to wash your hands and for the dishwasher it kicks and sends an Error code starts with an upside down F than a 2.2 and it will flash the fan inside will kick in and cut off than back on again I just bought the house not too long ago and noticed the boiler is older than the house it was installed on 06 and the house was built in 08 doesn't make any sense I'm at my wits end anyone out there that could give me some insight instead of the plumbing company charging me $70 an hour just to stare at it bill me and not do anything or have any suggestions or anything just to say I need a second opinion call up someone else so now it's $140 an hour just to screw around need help ASAP

    So I have never seen that code with a Trinity unit, does it have the Fenwal control? Typically it will have an ER_ _ code or a flashing on the board. Could you let us know what control it has and submit a pic of the error code and piping.

    As far as I know, that is saying T2.2 which is the version Sentry control you have on the unit. I would suspect you need a qualified tech to come out and service it. Where are you located?

    Check grounds on Fenwal and you dont want any interference with black cable.Look for knicks in it.Not familiar with boiler but would def. get tech support to help you through it.

    Just to add to the above, whoever comes out needs to do a combustion analysis to ensure the boiler is set up correctly.
