Hi everyone,
I need help with something going on with my boiler. Last Friday I had an F28 ignition error on my Vaillant EcoTec Plus 832. A reload worked and it was back in operation. On Monday it happened again and it took few reload to make it back to work so I called a plumber that came and cleaned the electrode.
The boiler seemed fine and I decided to do a job that has been postponed for too long, put a shorter and clean cable for the VSmart installed in the boiler.
At that time the boiler kept triggering the F28 error over and over so I decide to replace the electrode. It was fine for one day and then again with the error over and over. I decided to try the boiler without the VSmart connected (I physically unplugged the connector from the board and the boiler started working straight away.
I did all the VSMart cabling again and everything looked fine until the last two days where I had a couple of error again, one at 5:30 in the morning when the temp change for the day (so first start) and the other at the end of the day. During the day it was absolutely fine.
As an experiment I decided to change the VSmart algorithm from Advanced to Hysteresis and reset the heating curve and this morning at 5:30 the boiler started with no issue. It could be coincidental but who knows.
So here's the question to someone more expert than me: is it possible that the VSmart causes an F28 error?
If it happens again I'm gonna try unplugging the VSmart from the board and see what happens. Looking at the list of error in the boiler I can't see any F28 from when the previous owner lived here. The error started after I installed the VSmart in Jan (just 2-3 errors in 2 months since last week)
