How cani fix my Triton Opal 2?

You are not alone....
See the other post on the Opal 2 shower problems on How To Mend It .COM at:

The problems seem to be either the pressure microswitch or the power supply voltages - both can be fixed for under a few pounds, but may require soldering. Don't forget there are dangerous voltages inside your shower if it is switched on at the external shower switch, even if it is not running.

HI
poss problem could be the heater canister is scaled up with lime scale thus causing lack of water inside the heater canister and over heating of the smaller amount of water, are you in a really hard water area and how long has the shower been installed if hard water area and over 2 yrs installed then the unit requires descalling but this is not an easy job ie heater canister has to come out and liquid descaler used to descale inside of canister,or a replacement shower fitted. hope this helps
