Econpact 225c F5 no heating/warm water

[Wvfn]

Hallo,

I am sorry to write this in English, as I have just moved to the Netherlands and have yet to learn some Dutch.

Long story short - my boiler (Econpact 225c ) has started to show the F5 error in these past few days and the heating is not working (as I just moved in, I do not know if it did before), and I lost hot tap water as well. Using google translate I found that the pressure in the system was too low (under 1.5 bar) - so I filled the system with additional water and now the manometer shows that the pressure is 2.0 bar.

The F5 error, however is still present, and I still have no hot water and no heating.

What could be wrong and what could I do by myself to at least have the hot water? I can live without heating until the technician arrives, but not having hot water is going to be difficult.

Ik dank u wel!

Did You unplug the powercord while refilling?

Did you push de ¨R¨ button?

Yes, and yes. I tried to hold R button for more then 10 seconds to see if it would reset, I did it multiple times with no effect whatsoever.

I suspect a broken pressuresensor.I'm sorry but you'll have to boil your water on a stove, this boiler needs a tecnician.
