Overheat Thermostat or thermostat sensor...

I am attaching the pdf document I found
(diagram on Page 30, items 16 & 17)...

http://www.freeboilermanuals.com/assets/pdf/baxi_disc/SOLO%203%20%2030-80PF%20SYSTEM.pdf

Several options... (most likely 71 & 72 ... Page 44)

Either unit could be defective... or legitimately REACTING
to a PUMP or FAN failure...
(or faulty wire to the control board)

The "LOGIC" on your control board is looking
specific temperature within a MINUTE...

Failing to see the Overheat Thermostat or
thermostat sensor... in a specific state ... the logic
will cut the fuel...

The "MANUAL" includes a trouble finding guide
(APPROXIMATELY after PAGE 44)...

Save the SWAPPED OUT PARTS AS GOOD SPARES
and buy yourself SPARE "sensors" so they will never
fail again).

Hope this helps.

F04 is a fume thermostat fault

Make sure the gas inlet & outlet pressures are correct (manometer) & that the primary air mixture is adjusted correctly. Check to make sure you have 1 square inch of outside air for combustion per 2000 BTU's rating on the boiler.

Hi it sounds like the pump is not working or diverter valve not working check to see if pump is working on ch mode as well as valve , pump could be stuck ,

this will be your diaphram inside your divertor valve.
the one that looks like a spaceship.
it will e split.

it could just be the presure switch try bridging it out and see if burner lights
