Riello RDB Red Lockout

[nicthetheif]

Hi Guys
I have had this several times where the oil boiler's red lockout light comes on, this time it was due to low water pressure in the system. I have topped this back up to spec but the red lockout light is still on.
If i press the illuminated red reset button nothing happens. It doesnt make a sound or try anything.
I have turned electric off to reset it, but the light comes back on immediately when power restored.

Any help on how to get it to start would be great.

Thanks

You need someone who is qualified to work on oil by the sounds of it

As above. Not a diy repair.
