What do you mean 90%? Boiletr pressure gauges are usually calibrated in
bar, usually 0-4 or 0-6 bar. Is yours actually marked in %? If so do you
mean that it's going to a high setting or a low one? Most boilers will
cut out if the water pressure is too low. Look through Google's archive
of this group (e.g. "boiler pressure low") for _many_ discussions of
such problems.

Your problems may have nothing to do with the pressure.

Could it be the temp guage he's looking at 90 degrees C? Low pressure causing over heat cut out cured by reset? Find the pressure guage when boiler cold, make sure it is 1bar to 1.5bar, that shgould sort you out.
