This function allows the testing of individual com-

ponents and the ability to check switches for proper 

function. This function also tests the Soft Heat server's 

status on the brewer (in place or removed), and the 

funnel sensor coil's frequency (diagnostic tool for 

troubleshooting purposes only).

  This will allow the operator to test the operation 

of individual components and outputs of the brewer.  

The components that can be individually tested are as 

follows:

Brew Valve

Bypass Valve

Funnel Lock (Optional)

Server

Refill Valve

Tank Heaters

Heater Contactor

Left Brew Valve

Left Bypass

Left Funnel Lock

Left Server

Right Brew Valve

Right Bypass

Right Funel Lock

Right Server

Refill Valve

Tank Heaters

Heater Contactor

1.  Place brew funnel(s) into rails on the brewer (both 

sides on DUAL brewers).

2.  Place a Soft Heat server(s) beneath the brew 

funnel(s).

3.  Press and hold the upper right hidden switch until 

display reads UNITS. Release the switch. Continue 

to press and release switch until SERVICE TOOLS 

appears. 

4. Press YES to run tests on various components 

and outputs within the brewer. Pressing NO will 

exit this function and advance to next function 

screen.

5.  The display should read TEST OUTPUTS.

6.  Press and release YES. The display should read: 

BREW VALVE on SINGLE brewers

 

LEFT BREW VALVE on DUAL brewers.

7.  To test BREW VALVE, press ON. If the brew valve 

is functional, water should run from the brewer 

(left side on DUAL brewers)

8. Press OFF to end flow of water.

9. Press NEXT to advance to the next component to 

be tested.

NOTE: To bypass testing any component, press NEXT 

to advance to the next one, without testing the previ-

ous component.

10.  To test BREW BYPASS on SINGLE brewers or LEFT 

BREW BYPASS on DUAL brewers, press ON. If the 

bypass valve is functional, water should run from 

the brew bypass (left side on DUAL brewers).

11. Press OFF to end flow of water.

12. Press NEXT to advance to the next component to 

be tested.

13. To test FUNNEL LOCK on SINGLE brewers or LEFT 

FUNNEL LOCK on DUAL brewers, press ON. If the 

funnel lock is functional, the lock will come down 

to hold the funnel in place.

14. Press OFF to retract the funnel lock.

15. Press NEXT to advance to the next component to 

be tested.

16. To  test  SERVER on SINGLE brewers or LEFT 

SERVER on DUAL brewers, press ON. If the server 

and the sensor are functional, the light on the lower 

right corner of the server will illuminate.

17. Press OFF to end testing of server.

18. Press NEXT to advance to the next component to 

be tested.

19. For DUAL brewers, follow steps 7 through 15 to 

test the right side components.

20. To test REFILL VALVE, press ON. If the refill valve 

is functional, the sound of the valve operating will 

be heard.

21. Press OFF to end testing of refill valve.

22. Press NEXT to advance to the next component to 

be tested.

23.  To test TANK HEATERS, connect a voltmeter across 

each of the tank heaters to check for voltage.

24. Press ON. The correct voltage should be present 

at the heater terminals.

25. Press OFF to end testing of the tank heaters.
