PROGRAMMING FUNCTIONS - LEVEL 2 (cont.)

SERVICE TOOLS

Thisfunctionallowsthetestingofindividualcomponents and the ability to check switches for proper function. This function also tests the funnel sensor coil’s frequency (diagnostic tool for troubleshooting purposes only).

Procedure to test components and outputs:The following components can be individually tested: Brew ValveDilution Valve Refill Valve Tank Heater Relay Tank Heater Triac1.Place a funnel into the rails of the brewer.2.Place a server beneath the funnel.

3.Press and hold the right hidden button until the dis- play reads SET LANGUAGE. Press the right hidden button until the display reads SERVICE TOOLS.

4.Press and release YES. The display should now read TEST OUTPUTS? Press and release YES to test individual components and outputs. Pressing NO will advance to the next programming function,

TEST SWITCHES.

5.The display should now read BREW VALVE. To test the brew valve, press ON. If the brew valve is functional, water should run from the funnel.

6.Press OFF to end the flow of water.7.Press NEXT to advance to the next component to be tested.

NOTE: To bypass testing any component, press NEXT to advance to the next component without testing the previous one.

8.The display should now read DILUTION. To test the dilution valve, press ON. If the dilution valve is functional, water should run from the nozzle.

9.Press OFF to end the flow of water.10.Press NEXT to advance to the next component to be tested, REFILL VALVE.

11.To test the REFILL VALVE, press ON. If the refill valve is functional, the sound of the valve operating will be heard.

12.Press OFF to end testing of the refill valve.13.Press NEXT to advance to the next component to be tested, TANK HEATR RELAY.

14.To test the tank heater relay, connect a voltmeter across each of the tank heaters to check for volt- age.

15.Press ON. The correct voltage should be present at the heater terminals.16.Press OFF to end testing of the tank heater relay.NOTE: The tank heater will automatically turn off if left on too long.17.Press NEXT to advance to the next component to be tested, TANK HEATR TRIAC.

18.To test the tank heater triac, connect a voltmeter across each of the tank heaters to check for volt- age.

19.Press ON. The correct voltage should be present at the heater terminals.20.Press OFF to end testing of the tank heater triac.

21.Press NEXT to TEST OUTPUTS?. To exit program- ming, press and release the ON/OFF button to return to the MAIN SCREEN.
