TROUBLESHOOTING (cont.)

PROBLEM

Spitting or unusual steaming from sprayhead or air vent.

Dripout time too long

PROBABLE CAUSE

1.Lime buildup

2.Temperature probe

3. Control Board

1. Funnel tip

REMEDY

Inspect the probe and tank assembly for excessive lime deposits. Delime as required.

Remove the probe from the grom- met and submerge in a water bath of approximately 70°F (21°C). Connect an ohmmeter to the pins in the connector. At 60°F (16°C), the reading should be 15.3k ± 2k OHMS, at 70°F (21°C) 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, reconnect to the control board.

Remove power from the brewer. Connect a voltmeter across the tank heater. Reapply power to the brewer and refer to testing outputs on page 56. If the voltage measured when the tank heater is turned on is very low or zero, then substitute a control board know to be good working order.

The brew funnel should be cleaned thoroughly before each brew cycle to lessen the chance of tealeaf or ground particles clogging the dripout tip.
