Valliant ecoplus 824 not responding

Hi all, first post so hello

I'm having trouble getting my heating going again after the summer; thermostat is definitely working and sending a signal to the boiler. The boiler is also functioning perfectly in terms of hot water, just not heating.

A quick shifty through the manual said that the msg on the panel should go from S! to S4 once the heating demand is received. It's stuck on S0...

Does anyone have any ideas about the issue?

Any help hugely appreciated

What's the heating temperature set to? Is there an umberella symbol on the display.

Heating temp set to 54, no umbrella symbol and the radiator symbol is flashing...

So your getting 240v into terminal 4?

Not sure what that means, sorry. How would I check?

 

[bellairaphon]

Do you have a multimeter?

Do you have a multimeter?

I don't, no. If I get one what would I need to do?

 

[bellairaphon]

Test that your getting 240v on terminal 4 on the curcuit board. Then if you are check the divertor valve is getting a 24vdc on the brown and black wire spike when heating is selected. If not then I'd be looking at a board fault.

I'll be honest if you don't know if you have a multimeter, you shouldn't be in about areas that could have 240 volts running through it.

That's a recipe for disaster!

Truesay!
Will get an expert in, I was hoping it would be a matter of someone telling me to flick a switch and all would be well.

Everyone always thinks that!

The real world is different.

All that a non technical owner can usually do is ensure the system pressure is correct and read any fault codes!
