I did a search but couldn't find anything exactly like this problem, any ideas please?
Our Vaillant Turbomax Plus boiler developed a problem where hot water does not appear.
On examination we first found that the water pressure had dropped to about 0.8. We followed the procedure in the manual "Filling the heating system" and successfully returned it to 1.5, however the problem was not fixed. (So this may not be relevant.)
We have tried the re-ignition several times without success. The system behaves as follows when this is tried:
1) to begin with none of the three lights are on. No failure code is shown, temperature is ambient at about 20 degrees Celsius. status mode is S.00 (no heat demand).
2) press the ignition button for a second and release. It gives three clicks, the last one is a shorter double-click. I don't know what it normally sounds like. During this the status codes go s10 (hot water demand), s11 (fan running), then s17 (pump overrun). No hot water appears after several minutes.
To view the status codes I am repeatedly pressing the "i" button, I might have missed some if they would only briefly appear but I can't see s.13 "ignition sequence" and s14 "burner ignited", there is also no other burning noise.
Any ideas?
If I just take off the cover will I be able to see if ignition is happening, or some other part has burnt out etc, without actually moving or dismantling the components? And is that safe?
We followed the fault finding diagram through to "Does the boiler commence ignition" but are stuck there. (Both answers lead to having to replace parts though )
Any advice would be much appreciated.
regards,
V
