You are likely getting "luke warm" water because the brew boiler water is pre-heated in the steam boiler on its way to the brew boiler.
I'm betting that your temp sensor is bad. The temp sensor is a thermocouple that simply inserts into the thermocouple well on the brew boiler, so no need to get a metric hex wrench and remove the well. There is some kind of "goo" (pipe threa sealing compound, I think) to help keep it seated and in good thermal contact with the sides of the well. When the brew boiler is at full temp, I found that you could pull the thermocouple out of the well. When the boiler was cold, the thermocouple was firmly seated and even a firm tug would not make it budge. My 3-year old Brewtus II had a similar issue. I found that the wiring on the thermocouple, where it goes into the thermocouple well, had deteriorated and disintegrated so badly that the wires were exposed and had likely shorted out. If you have access to a multimeter you can disonnect the thermocouple at the "box" and test for continuity and shorting of the thermocouple. First connect to each end of the leads and check for continuity (i.e., an unbroken circuit within the thermocouple). Then you can test for a short by connecting to one lead of the thermocoupld and someplace on the brew boiler, and then the end of the other lead and the brew boiler. If you can complete a "circuit" that way, you have a short. The thermocouple on my Brewtus II had deteriorated so badly that it did not come out cleanly. I used a drill bit that just fit into the well and CAREFULLY hand drilled out the remains of the old thermocouple head that did not come out when I pulled the wire out. If your thermocouple is the issue, then you have two options: 1) replace the thermocouple or 2) replace the whole "box". If you have the AKO-13120/01 PID Thermostat "box" like I do, WLL does not carry the AKO-14901 NTC thermocouple, which is require for the AKO-13120/01 to work properly. The only vendor I could find on this continent that had the part is Furneco International (www.furneco.com) in Canada. They sell it for $14.50 plus shipping. I found a few in Europe (moslty Spain), but they did not ship to the US or you had to purchase the thermocouple in bulk. -- You received this message because you are subscribed to the Google Groups "Brewtus" group.
