7. The secondary hi-limit thermostat keeps
activating.
Test the hi-limit thermostat. Replace it if necessary.
Inspect the hi-limit thermostat wiring for loose, damaged or overheating wires or terminals. Repair or replace wiring
as necessary.
Test the thermostat for proper temperature adjustment. The recommended temperature is between 188
°
and 192
°
F.
Test below the brew cone with water only. Temperature higher than 192
°
F may cause the hi-limit to activate.
WARNING:
If the thermostat cannot be adjusted properly it should be replaced. The thermostat is calibrated at the factory
and no attempt should be made to recalibrate it. Use only original or authorized replacement parts.
8. The brewing temperature is either too hot or
too cold.
Inspect thermostat bulb for excessive lime buildup.
Is the thermostat bulb in clip and attached to the immersion element? Reattach bulb if necessary
Adjust or replace the thermostat. Turn the adjustment screw clockwise to increase the temperature, counter-
clockwise to decrease. Turn the adjustment screw a maximum of 1/8 turn per adjustment. Retest and adjust again

If the thermostat cannot be adjusted properly it should be replaced. The thermostat is calibrated at the factory
and no attempt should be made to recalibrate it. Use only original or authorized replacement parts.
Test the thermostat sensor with an ohmmeter. The sensor should read approximately 100,000
Ω
at a normal room
temperature of approximately 25c. As the heat to the sensor increases, the reading should decrease to zero.
Inspect wiring for correct, loose or damaged wires or terminals.
Test for correct voltage at the power supply.
9. The brewing cycle is too slow.
Inspect and clean the spray head, siphon tube and reservoir down spout.
Inspect and clean the brew cone
10. The beverage level is inconsistent.
Inspect and clean the spray head, silicone tubing and siphon fittings.
Inspect and clean the brew cone.
11. Water dripping from the spray head.
Inspect and clean the spray head, siphon tube and reservoir down spout.
Inspect and tighten siphon tube. Replace “O”-Ring if necessary.
Test the brewing temperature. Adjust the thermostat if necessary.
12. Water leaking from unit.
Inspect gaskets. Replace if necessary.
Test the brewing temperature. Adjust the thermostat if necessary.
