Test Procedures: Thetestproceduresforthecontrolboardwillvary depending upon the problems experienced bythebrewer.RefertotheTroubleshootingsec-tionwhichisdividedintothreesections,RefillCircuit,HeatingCircuit,andBrewingCircuit.

Check for Power to board:1. Insert one meter lead in J1-pin 1 and theotherleadinJ1-pin2.2. With the power connected to brewer, thevoltage reading to the board should be the line voltage rated for that model.If no voltage is present, check wiring to the board. If voltage is present, and brewer does not power on, replace board.

Removal and Replacement:1. Disconnectbrewerfrompowersource.2. Disconnectthewiresfromtherelayonthecontrol board.3. Disconnect the 10-pin connector (main har-ness) and the 3-pin connector (level probe har-ness) from the control board.4. Disconnect the 10-pin connector (ribbon cable) from the control board.

Test Procedures:1. Refer to the Programing Section for Service Tools/TestOutputs/BrewValve.2. Besurebrewfunnel&serverare inplacebefore activating valve.3. Check the valve for coil action. Turn on the valvewiththetestmode.Listencarefullyinthevicinityofthebrewvalveforaclickasthecoilpulls the plunger in.If no sound is heard as described, proceed to #4. If the sound is heard as described, there may be a blockage in the valve , hose, tank, or sprayhead. Disconnect the brewer from the power source. Remove the valve and inspect for blockage, and de-lime all related areas.4. Connect the voltmeter leads to the coil ter-minals.Turnonthevalvewiththetestmode.NOTE: Due to the internally rectified coil, the indication will be 120VAC all the time. Set the meter to DC volts. The indication should be 170VDC when activated. If the polarity ofmeterleadsarereversed,readingwillindicate-170VDC.(Double these readings for 240 volt coils)
