Hello, you are saying it fires up for seconds and then cuts out? Is there a fault code that comes up on the display?
Customer reply replied 1 year ago.
only flame fault
Customer reply replied 1 year ago.
IT WILL TRY TO START THREE TIMES BEFORE SHOWING A FLAME FAULT
Plumberpro, Home Appliance Technician replied 1 year ago.
Hi , then you will need to change your flame retification( sensing) probe. This senses when the boiler is lit and opens the full gas valve. Fairly cheap and easy to change
Customer reply replied 1 year ago.
Already changed the sensing electrode
Plumberpro, Home Appliance Technician replied 1 year ago.
Hi,I still believe it will be the thermistors, but have you. Checked the pump is running?
Customer reply replied 1 year ago.
Pump and fan both working
Plumberpro, Home Appliance Technician replied 1 year ago.
Ok, that's good..I still think it will be the themistors. They can be the end on ohms with a. Multimeter. They are usually within a certain range
Customer reply replied 1 year ago.
Ok I will order new ones
Customer reply replied 1 year ago.
About to order new temperature sensors do you think it could have anything to do with the safety thermostat
Plumberpro, Home Appliance Technician replied 1 year ago.
Yes, I think k the boiler is cutting out on overheat stat because a faulty thermister is allowing the temperature to get to0 high
Customer reply replied 1 year ago.
BOILER WORKED FOR A DAY ,THIS MORNING IT STOP WITH THE SAME THING,I HAVE JUST RESET AND WATCHED IT FOR AN HOUR ,IT HAS BEEN WORKING FINE ?
Plumberpro, Home Appliance Technician replied 1 year ago.
Intermittent faults like This are really difficult to diagnose.. I wonder if the overheat stat is playing up
Customer reply replied 1 year ago.
Did you mean the safety thermostat,l changed that when I fitted new sensors
Plumberpro, Home Appliance Technician replied 1 year ago.
Yes, I did. There's. Not many things it could be and you have changed nearly all of these. The only thing left is the pcb.
Customer reply replied 1 year ago.
That was changed about 18 mouths ago
Plumberpro, Home Appliance Technician replied 1 year ago.
This is really difficult. Somethings dropping out or tripping out out. Have you checked the flow Microswitch. Maybe keep the switch open manually [with tape or something ] and see if it runs ok .
Plumberpro, Home Appliance Technician replied 1 year ago.
Have you changed any leads, ie flame recognition probe lead or ignition lead. Something may be getting hot and failing
Customer reply replied 1 year ago.
Fitted a new lead when the flame probe was changed
Plumberpro, Home Appliance Technician replied 1 year ago.
Hi , just some to baxI. They recommended cleaning the gauze filter on the isolation valve on the return o. The right hand side
