Troubleshooting Procedures
Remove power from the brewer. Connect a voltmeter across one of the tank heaters. Reapply power to the brewer and refer to Testing Individual Components. If the full supply voltage is measured when the tank heater is turned on, and zero voltage is measured with the triac off, then the triac is good. If half the supply voltage is measured, the triac is defective. If very low, or zero voltage is measured, there could be a defective triac or a defective control board.
Spitting or unusual steaming from sprayhead or air vents. (Water too hot)
4.Electronic Control Board
1.Triac
Perform the above procedure for testing triacs. If the voltage mea- sured is very low or zero, then substitute a control board known to be in good working order.

2. Lime Buildup
CAUTION - Tank and tank compo- nents should be delimed regularly depending on local water condi- tions. Excessive mineral buildup on stainless steel surfaces can initiate corrosive reactions resulting in seri- ous leaks.

Inspect the tank assembly for ex- cessive lime deposits. Delime as required.
