Vaillant ecotec plus

Didn't have boiler manual
fault code is S97
Water sensor ?
Hot water is warm and not hot
Heating is ok

Yea normally blocked or not working

S code on Vaillant is a status code, that one is normally pressure sensor test running and it might cause restricted performance. If you depressurise the Boiler, the gauge pressure should read zero, if it doesn't then the pressure sensor will most likely need replacing. They slowly become blocked with magnetite.

Need to get on with vaillant then and there boiler course. Might help us
Where is it located as I haven't looked in the boiler yet, was there to sort the solar thermal system that stopped working.

More often than not, front bottom left,

That's it!

A few will be left hand side up under primary heat ex.
It's a wet connection by the way!

Thanks
Could this fault also affect the bar pressure as the warning pipe was passing slightly

Yes, If it is reading wrong it can cause a few probs.
