The TOWER of POWER uses a lab grade sensor and high resolution meter. It is
accurate to /- 0.5 F (0.25C). Use this sensor to calibrate your mash
thermometer. Place both sensors in a thermos of water at about 154 F (68 C)
It is normal for the mash temp to lag behind the recirculation temp. Wait for
temperatures to stabilize.

Check that sensor is plugged in, and no pins (3 total) are bent or damaged.
If this does not resolve the trouble replace sensor.
Pump Won’t Flow
Check that all appropriate valves are open
Check that mash is not stuck (compacted). See below
Check that all hoses downstream of the pump are empty. Install a bleed valve after
the pump to vent air and allow the pump to fill with liquid. For Tower users, the
sample port can be used.
Mash is sticking
Reduce flow rate
Ensure you have done a dough-in WITHOUT the pump on to allow air to purge from
the grain bed.
Check that grain crush is not too fine. Husks should be intact. Use rice hulls if
crush is OK.
Ensure that lauter hardware (piping, slots, perforations) are not plugging
Maintenance
The TOWER of POWER

temperature control system requires little maintenance. Inspect fasteners, wires
and hoses regularly and replace as needed ONLY with genuine Blichmann Engineering
