HTP UFT 100 error 11 after big windy wet storm

panga

Reading through possible issues in here. Ignitor looks fine, flapper after blower is in one piece. 

Error code 11 shows. 

Had a very windy wet storm night before and lost hot water in the house. The blower had some water in it when I disassembled, not a ton but few tablespoons maybe.. it’s direct vented through the wall it’s mounted on into a combo intake exhaust vent flange on side of house. 

I can hear gas valve open, ignitor clicking, don’t see any flame through sight window. 

Any ideas? Plumber who installed it for me passed away last year so can’t get his help. Unit has been running strong for almost 4 years since new install 2019. 

Thanks!

Randomly started working… seems fine as of now.

has anyone serviced the boiler over these 4 years?
"The blower had some water in it when I disassembled, not a ton but few tablespoons maybe.. "
I would take a close look at the condensate system and trap, and clear it,
then find someone to do a complete service,

Was a combustion analysis ever done?

Has not been serviced. Where can I find info on what this entails, the plumber locally who did these systems passed, and nobody else has much experience, I’m pretty mechanical and handy, probably rather learn myself then pay someone else to learn. 

No CA was performed, this was over the weekend, and it seems to be going fine now so didnt look for a technician. Please advise if and why needed. 

Thanks for the advice, much appreciated!

A combustion analysis is required to properly adjust and setup the boiler. It should have been done at the time of installation. Read the install manual. 

It requires a digital combustion analyzer and the training to know how to use it. 

Apparently, your plumber didn’t have one or know how to do it.
