My shower used to run fine, but just recently the temperature when on full power has decreased. It used to run fine when I set the temp gage to around level 3-4 (out of 10) The only way I can now take a shower at a more reasonable temperature is to turn the dial to a much higher temperature 8 - 9 but this has the effect of reducing the pressure. The shower I have is a Triton Amber II.

Any ideas people?

One of the elements is bad. You will need to take it down and find the bad element. I would just replace both of them. Here is a manual: https://dl.dropbox.com/u/8010163/amber3.pdf
