thanks for that you were exactly right!! got a screwdriver in there and it just popped off with four long pins connecting it -
anyway done what you said and turned it back on and still nothing, tried pressing + - again and it fired up into sfh mode again
really appreciate your advice...
ok so heres the boiler issue done a little video
first one is of it kicking into sfh mode second is after it hits max temp and shuts off

when i hit the + and - button together everything fires up and it displays SFH (water pump starts running etc) however hit max temp then shuts off in this mode
sorry bud, yes its the mechanical timer and yes it has a green light etc
when i set it to the timer to on , the green light comes on but no fault code when i press (i) just gives temp and 5.30
Hi,
I have a Vaillant Turbomax plus 824E
i have a bit of an issue wondered if any experts could guide me as to what it is. i have had a plumber friends glance over it but as he does not normally service and fix boilers so doesn't know whats wrong.
the hot water kicks in...
