Riello 40, has to be started manually

biko

After getting tank filled up for winter (if this matters) I tried to get burner working.
Usually this involves just turning on a switch inside the house but heating wouldn't come on.

It seems most times now when I turn it on from inside it won't kick in, I have to go outside to the burner and press the reset button a few times for it to start up.
Have been like this for about a week.
It's no biggie to go outside and manually start it but I'm wondering if it needs cleaning/servicing or something?

A service would be a good idea if it has'nt had one for a while.

A service would not go astray but unless it is a partially blocked injector, you will probably get billed for a repair and a service.

It shouldn't be anything major, maybe a faulty capacitor and these cost about €15

Sounds like a bit of dirt or moisture may have mades its way in to the oil/line or to the burner.
A service and nozle change should rectify it.
Oil Filter at tank should be cleaned and inspected at every service.

Thanks lads, guess I'll have to arrange a service to be performed.

Ok, my money is on partially block injector or capacitor.

I might as well hijack also.
Not one of you asked biko what cycle his burner is taking.
A few simple checks.
1. Did oil run out completely before refill.
2. When was it last serviced.
3. Is fan running before going to lockout.
4. Is burner trying to fire up.

If motor fails to run first time every time then it might be capacitor,OR could just be a sticky motor and WD40 will get you going.
I do'nt think its a partially blocked injector as this would only cause unstable flame.
As far as i'm aware this type of riello does have a photocell.
BUT ALSO...unless biko is familiar with the internal workings of his riello then he would be better getting a tech to take a look.

The nozzle only needs changed in a domestic burner every 2nd or 3rd service.

There is no doubt he needs it looked at.

But biko did state that the burner did start after multiple resets. This would indicate an indeterminate problem. It could be a stuck fan/main shaft. A partially blocked injector will cause lock out.

I'm not sure Mickey how a partially blocked nozzle will cause lockout.

Micky Dolenz

For loads of reasons, the main one being, lack of oil delivery, to complete combustion causing photocell to signal lock out.

Agree with above exept:
Nozzle should be changed every service ( Usually once a year).

You can't properly service a oil boiler without checking oil pressure and air settings/ CO2,Co, Exess Air Flue temps etc.
You need to ensure thae nozzle is working 100% so I would always put a new one in ( it's only a few euros and I include it on the price of a service). Also if you are servicing the boiler properly you have to open up combustion chamber, burner, clean / inspect electrodes.... so you might as well replace nozzle while your there.
Also inspect oil filter and check oil lines............

Would oil not still be delivered to chamber in the partially unblocked part of nozzle. Albeit the flame will be offset but still a flame.
