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.

Further background reading is in the Sealed CH FAQ Your problems may have nothing to do with the pressure.

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