Triton Trance electric shower suddenly wont heat fully.

Hi all,
I have had a look on the internet to see if I can get this sorted without having to post but I can't figure it out!
Basically we have a Triton Trance 2nd generation electric shower which we bought and had installed 20 months ago.
It's always worked great with good power and is nice and hot, however the other day it wouldn't heat unless we had the temp at its highest and even then it's not that hot.
We have plenty of pressure at the setting we normally use but its stone cold at that setting.
Prior to finding out that it wasn't working on Monday morning (great start to the day) the day before I had to turn off the water at the mains as we had a leak downstairs which we have now sorted.
We turned the water on and everything else was fine, until we tried the shower.
ON the boiler I noticed the pressure was way down so I upped it to 1 and thats sorted now.
Could turning the water off at the mains cause this shower issue?

I contacted Triton and its under warranty as under 2 years old but without the receipt they wont help and we dont have it!
Any ideas what we could try to fix it?
Thanks,
Al

Probably need a new heater tank. These usually have 2 elements - you might be down to 1 if it just gets slightly warm.
