REMEDY
Remove the probe from the grom- met and submerge in a water bath of approximately 70°F(21°C). Con- nect an ohmmeter to pins 3 and 4 of the J3 connector. At 60°F(16°C) the reading should be 15.3k ± 2k OHMS, at 70°F(21°C¼ the reading should be 11.8k ± 2k OHMS, and at 80°F(27°C) the reading should be 9.3k ± 2k OHMS. If the probe is within these parameters, recon- nect the J3 plug to the control board.
Set the temperature to 200°F (93°C). Let tank temperature sta- bilize. If temperature in tank is above temperature setting by more than 7°F(3.9°C), replace the con- trol board.(See page 23)
Plumbing lines should not rest on the counter top.
The brewer must be connected to a cold water supply.
Remove the tank lid and clean inside of tank with a deliming agent, if necessary.
