Riello RDB won’t fire

[Euanm]

Hi,

I’m having trouble with my Riello burner.

Upon starting the fan motor runs for 10 seconds, then I assume it tries to fire (noise changes), after 4-5 seconds it goes to lockout. It hasn’t fired at all since this problem started.

We were close to running out of oil so I assumed this was the problem. Have since got the tank filled so there’s plenty of oil and pressure.

I’ve bled the pump multiple times. It was quite foamy but is now running normally. I’ve dumped oil out from the fire valve in case there was sediment. From what I can tell there’s oil running to the pump and at pressure.

Tried resetting with the photocell removed. The fan motor just runs and nothing else happens.

Before I call someone out is there anything obvious I’m missing or should check?

Thanks

What's the washing pressure?

I think it’s a system boiler/setup and so doesn’t have a pressure gauge.

We’re only a month in the house so I’m not hugely familiar with the setup.

On the oil pump, not the heating system.

Ah sorry, I don’t have a pressure test gauge so not been able to check.

Then leave it alone and find a competent oil guy.
