Glow-worm Ci F16 fault

Hi All

I have a Glow-worm boiler, model Ci, it is no longer under warranty. Honestly we never had problems with it, till today. We woke up and we realized that there is no hot water. Boiler display F16 error code. I tried resetting, no success. I can’t find user manual to figure out what does it mean and how to fix it? Can someone help?



Hi Rob,

Error F16 means a fault with flame detection. It is pretty serious fault, so I would advice calling a service guy, that will most probably clean or/and replace probe as well as lead and flame detection. Unfortunately this is a pretty common fault on Ci models.
