Heatslave 20/25 - lockout after low pressure, won't reset

[crappy]

Folks,

I have a 23 year old oil boiler which is like triggers broom.
This morning I woke to a cold house.

The pressure gauge on the boiler read zero (I had a leaking rad, forgot to refill). How filled and at 1.5bar

I've reset the boiler , the blower spins up for a few seconds and it locks out again.

The lockout light seems to flash twice then long on but I can't seem to find that as a code.

Thoughts?

The burner Lockout Light does not AFAIK reset the low pressure lockout which on my 18 year old firebird is the over temperature cut out (113C) which must be reset on my boiler by removing a little cover and pressing the reset button, however on mine the burner will not even attempt firing until reset.

Make and model of boiler would be useful!

As above overheat stat
If you really suspect pressure switch temporarily wire it out.

Thanks. Will take a look

The switch is very "sloppy" like it's not connected to anything internally. Is that right?

I press the reset piece, it travels around 6mm but there's no mechanical feeling to it.

Correct?
