Hi newbie to boiler issues here..
I have a problem with my boiler that I've been unable to solve. No indication of failure just happened. I hope you can help me fix it please.
My setup:
Family house, with Vaillant EcoTec810 Plus boiler + one Siemens RDJ10RF thermostat
Context:
Heating was working fine this morning but was set to off during most day. Turned on late afternoon, popped out for an hour and radiators were not hot. Boiler pressure was at 1.2 bar.
I've bled each radiators a small amount. Then pressurised system to 1.5 bar. Then turned heating on from thermostat which did ignite the boiler only temporarily for 5 secs. In pressing the override on the receiver it does not ignite the burner but the boiler clicks and fans start and stay on. I relearned the thermostat which is registering on/off of the boiler but no burner. Pressing the flame button does the same thing also.
The problem:
The hot water system works perfectly, but the heating system is not working at all. The boiler is not igniting but does so fine for hot water. The boiler clicks and fan stays on.
Signals:
The boiler shows status code 5.0 not sure what this means.
If I press the button on the thermostat receiver, the heating SEEMS to try to start, it turns on the icon of the heating pump (although not the burner), and remains in 5.0. There is an arrow symbol. It never starts the burner, and heating doesn't work. No error code is shown at any time.
I'm attaching some pictures for reference.
Can you please help me understand what is happening?
Thanks a lot in advance!!
