Too Much Coffee

I have a Vivi that I have had for a couple of years, bought used.

It has a couple of times now just sat there hissing steam, which I presume is the OPV. The pressure gauge was reading at the top of the gauge.

I am presuming pressure stat?

After a power down and open of valves to let off the pressure, it seems OK,

Am I righ in the idea that it's the pressure stat? If so where is the best/quickest place to get one? What is involved in replacing it?

Thanks,
Paul.

Hi Paul, it could well be the pressure stat but also check out this thread for other possibilities.

Thanks for that link - I have recently done a descale despite having really soft water round here. Might be worth trying taking the stat off and cleaning out the link pipe.

I'll order a stat anyway - this time of year will always be a lottery when it will arrive but I hav more chance of getting it the sooner I order.

If anyone has any tips on getting the stat off/on while still having a seal afterwards I would appreciate them!

Paul.
