Problem with Valliant ecotech plus 615

[Strego]

Hello,

I have a problem with Valliant ecotech plus 615. It has Drayton contorller. Last evening I changed settings from 'on' to timed, and it stopped working. I have a message 'S.30' displayed, even though there is only cold water running from HW tap. I checked settings, and everything is as supposed to be. Boiler makes sound, as if would like to start working, but there is no ignition. I tried to reset controls and restarted boiler a few times, but still would not work. Could anyone help???

S.30 means there is no demand from the external controls, try putting the programmer back to the previous setting and see if the boiler works.
