Have fitted a reconditioned one which seems to be working fine. However instead of LEDs it's showing the status on the LCD with some symbols.
I can work them out, but anyone have a link to what I imagine is a slightly different model, or more recent version ?
I had a look at the manuals I could see easily - they all seemed to show a vertical row of LEDs and no LCD.
Have you got the full model number?
(most Vaillant boilers have it on a sticker on the underside)
