gurutech67 :

Chris this is Scott let me try to find a manual to see what code FD4 means, and I'll see if it's something I can talk you through OK.

JACUSTOMER-lltnerhz- :

HI SCOTT HAD THE LI CODE BEFORE BUT OK AFTER RESET THEN KEPT SHUTTING DOWN SHOWING L1 TRIED RESETTING TODAY NOW F4 IS COMING UP THANKS CHRIS

gurutech67 :

Is it possible that the f4 is actually an f9 in the manual I located the f 4 dosent exsist but perhaps I have the wrong manual, are you in possession of one, by your boiler?

gurutech67 :

When you reset and the combustion blower runs do you hear a buzzing or clicking at all?

gurutech67 :

hello have I lost you?

gurutech67 :

Chris Are you there?

JACUSTOMER-lltnerhz- :

YES IM HERE

gurutech67 :

L1 is a lockout resetting results in erasing that code and initializing another cycle then coming up with a new code I had asked if during the restarting had you heard a buzzing or igniting sound?

JACUSTOMER-lltnerhz- :

TRYING TO RESET ON F4 BUZZING SOUND LI WAS OCCAISONAL RESTARTING

gurutech67 :

If it's not firing and you hear a buzzing /clicking , either the spark gap is misaligned or the gas valve is not opening , but because it ignites and goes out we'll rule out the valve, and the igniter/sensor should be removed and cleaned , how long since your last servicing of the boiler?

JACUSTOMER-lltnerhz- :

BOILER 2 YEARS OLD SERVICED APPROX 8 WEEKS AGO

gurutech67 :

Perhaps the ignitor/ sensor got out of alignment then. I would thing that is was cleaned then be sure all wire connections are tight.

JACUSTOMER-lltnerhz- :

DO YOU KNOW WHAT F4 CODE RELATES TO

gurutech67 :

I lost your last response,could you resend?

JACUSTOMER-lltnerhz- :

Do you know what f4 code relates to

gurutech67 :

F 4 code is not listed in fault code list, it goes from f3 to f5

gurutech67 :

the only code similar to f4 is an f9 which on display will look similar because of the led display. f 9 is all ignition challenges wich soungs like your challenge, however I will opt out and open question for another expert in case they have better information.

Hi My name is Brian. F4 is a fault code for the flow thermister. L1 is an overheat for no flow. This could be due to low water pressure a restriction in the flow, water pump failure, or even what its states a faulty flow thermister.

hi Brian what is a thermister

Plumber: Brian, Plumber replied 5 years ago
Hi Chris. A thermister is a thermostatic resister you will find them on the pipes leading to and from the boiler they will have 2 wires coming from them, basically as heat rises and or falls it changes the resistance and alters the current, this is then picked up by the pcb and used accordingly.
