Re read your post. I think you need something to check.the temperature coming out of the brew head to verify. I use the Klein Tools MM400. It's got a basic.temp probe that I just push up against the screen in the middle of the flow. It is coming out at the low temp or does it take time to heat up? How low is it going on the display? If the temp is too low to practically come back up to 93.or whatever you are awt at, I would think it has to be the probe.
