Firebird boiler

Davd

Hoping someone can help here - I've gone through some of the previous firebird 90 boiler posts but they didn't match.
I have a firebird boiler controlled by a Horstmann 3 zone controller. Obviously not using the heating zones at the moment but have the water controller set for half an hour each morning.
Problem is the boiler doesn't always come on for the hot water in the morning and sometimes doesn't come on when the boost button for the water is pressed but if the boiler controller reset button is pressed with the boost button on, then it fires up no problem. Problem is, this is happening intermittently.
When the boost button is pressed and the boiler fails to start, I can hear the water circulating motor switch on but the oil motor and burner don't start until the reset button is pressed.
Recently, I have changed the nozzle, cleaned the boiler and photocell. The 3 zone controller was changed a few months back aft the original packed it in.
Any ideas? I'm thinking firebird controller box but if its intermittent, it may not be electrical?

I presume the Lockout light is "up" before you press the reset button?.

if your pressing the reset button on the burner and not the one on the boiler stat

the first thing I would check is the motor capacitor

intermittent failure to fire would be an obvious symptom

Have been trying to get the system tonfreeze again to see if the lockout light comes on but as always with intermittent problems, it never happens when you try. It failed to turn on this morning but have hit the boost button a number of times today and it switched on.

Hi Jim, how would I check the motor capacitor for a fault or would I just replace?

Please post a pic of what you are resetting and if possible of the boiler also.

If it failed yesterday morning and then started by just pressing the boost button a few times and not pressing the burner reset then that would suggest something wrong in the programmer or maybe the motorized valve start signal from the cylinder, you could just try sometime just turning up the room thermostat on one of your heating zones and the press the boost button on this and see if the boiler fires up. Anyway have a look at these phots taken from a Firebird SE (non condensing) 90s boiler., they are self explanatory I hope. The burner reset photo is from a Riello G5X burner but they are all similar with the warning light in the centre of the reset button.

Thanks John. I was waiting for the issue to happen again before I reported back and it did so again this morning.
The red lock out light was on this morning when the boiler failed to fire up and the programmer timer for the hot water switched on.
By pressing the lockout button, the boiler immediately fired up and continued until the programmer switched it off.
I'm at a stage where I want to get a plumber/electrician in but because of the intermittent failure, it will probably work fine when they are in and fail as soon as they leave. I had tried to get it to fail over the weekend but anytime I pressed the boost button, the boiler fired.
Attached are photos of my boiler which is the same as you have attached.

you can check it with a multimeter but it will have to be able to check capacitance

you can purchase a new one for approx. 15 eu

Just to follow up, I couldn’t get a hold of a multi-meter to check the capacitor but took a chance on it after Jim’s advice. This seems to have done the job as I’m now 2 weeks issue free and it would normally go 2 days tops before the heat failed to come on.
Had a new programmer fitted recently following issues with the heating turning itself on intermittently and that seemed to sort those problems.

Thanks guys.

not sure about the memory either e.g [ fitting materials ]:)

Guys
OP (David) changes nozzle himself on indoor boiler and Ye tell him about capacitor.

Anybody want to tell him about carbon monoxide and the benefits of proper servicing with FGA?

OR AM I JUST PARANOID ABOUT INFORMATION WE REVEAL ?

jimf

in hindsight I think I am to dangerous to be posting on here on the p&h forum

so in future I think I will stick to religion and sexual matters

Should it follow on from the above then that a analysis of the area surrounding a indoor boiler should be tested as well in case of boiler casing leaks etc or is this "overkill" or is any form of test normally carried out apart from a visual?

room test around all joints and gaskets on the boiler would be advised as good practice

it only takes a few minutes

also a co alarm should be fitted in the area where boiler is fitted

hi tom 44

just been reading back over this post again and I do agree with your input above last night

but may I suggest if you think we / me are giving dangerous advice maybe in future you might advise us at the time

not 24 days after the thread was started
