A neighbour has a Vaillant ecoTEC plus combi.
It appears completely dead, i.e. the LCD display shows nothing at all.
I believe power is present at its FCU as the neon is on.
I’m not familiar with this boiler. Does it normally show something on the display if power is present but the boiler is not running?
An engineer attended last week because there was a drip from the bottom of the case; a split condensate hose was replaced. It has worked OK for a few days until now. (I wonder if drips of condensate have got into the electrics, and have taken a while to kill it?)
No doubt they will get someone out again but if anyone has any ideas about obvious things to check now, that could be useful.
