A few weeks ago we started setting the hot water to 43oC instead of 45oC, and then it was 40oC instead of 43oC. In short we were having to set the Baxi boiler to a lower water temperature in order to have a tolerably hot shower. Both my wife and I thought this was our imagination, but before much longer we were having to set the hot water temperature dial as low as it would go, and it was still hot enough to cook our flesh.
I tried to google a few phrases like 'baxi duo tec too high temperature' but didn't find any conclusive information on how to fix the problem. Then the error code E50 started flashing up and we lost all hot water.
