Potterton FF80 boiler, pilot light has gone out how do we relight

A lot of pilot lights have a thermal coupler... the pilot light must be lit for several min to open the coupler so the pilot light will not go out.... the newer systems use an electronic ignition and no pilot light and need power to autostart but the coupler may be gone if you are holding that pilot start button down for several min and the pilot light is still going out..ps.. leave it in pilot mode for several min after initial start up before turning turning full burner operation operation operation operation operation operation operation it will snuff out the pilot light.

These are designed not to light once the thermocouple fails.the thermocouple has a small wire that positions in to the pilot light which checks the pilot is on and keeps the gas governed.once the temperature drops it shuts off the gas to prevent a build up of gas in a room where a pilot light has gone out.this is why you need to hold the button in on reignition to allow the thermocouple to heat up so the gas keeps open.
Try to relight by turning on the gas ....pressing down and holding the button for at least 10 seconds whilst firing the piezo to ignite flame.do not release gas button for at least 10 seconds then slowly release.if the flame on the pilot will not stay alight....then it is likely the thermo has failed.try cleaning the metal wire that is above the pilot jet.still no joy then it needs replacing.hope my comment is of help...please vote.

need to change thermostat and a thermocouple

In general, large button from gas valve push in & hold 20-30 secs at same time push electronic lighter/ignition button to light pilot. Remember to hold in only gas button. the pilot light heats up a thermo couple [u can see this in the flame] and when hot enough allows the main gas through and the pilot to remain on.
If not then either thermo couple not heated for long enough or
it may need replacing

turn honeywell gas control clockwise and push in then spark egniter hold for 20secs then ease off button slowly pilot sound remain alight

you need to reset it but if it dont light you prob have rectifaction fault

TAKE A SHPO VAC AND CLEAN AREA. MAKE SURE YOU PAY SPECIAL ATT. TO THE PILOT LIGHT. FIND BUTTON HOLD IN AND IGNITE DONT LET GO WHEN IT LIGHTS FOR AT LEAST FIFTEEN SEC.. YOU MIGHT ALSO HAVE TO TURN THE THERMASTAT OR KNOB TO PILOT FIRST. AFTER IT HAS LIT TURN UP FLAME
