Hi, my 102 pumps loads of water, but I am surprised at just how hot the block gets - too hot to hold your finger on for more than a moment. Is this normal or should I be worried. Seems strange when a good quantity of water is apparently circulating.
the temp should be about 140F too hot really to want to cuddle it for long! Unless you have a hot spot caused by a partial blockage it sounds about right!
