Hi,
Have Triton electric shower Opal 10.5kw, less than 2 years old a few weeks ago it started going hot then cold about every 30secs. Low flow rate light comes on when it goes cold but pressure should be ok. I have pressurized water system set at 2.25bar ( Triton say 1.5bar is suitable ) Flow rate of 36ltr per min (Triton say 11ltr per min is suitable ) Also have water softener so no scale problem.
HELP!! jsgreg.
