8. Control board or dispense valve

If the switch panel is operating prop-

 

 

 

 

erly, proceed as follows. Attach a

 

 

 

 

voltmeter to the terminals of the

 

 

 

 

dispense solenoid. Connect the

 

 

 

 

brewer to the power source. Turn

 

 

 

 

on the brewer and press the BREW

 

 

 

 

switch. Voltage should be present

 

 

 

 

at the solenoid terminals. If voltage

 

 

 

 

is not present, refer to the wiring

 

 

 

 

diagrams and check the wiring har-

 

 

 

 

ness. If voltage is present, check for

 

 

 

 

continuity across the terminals of

 

 

 

 

the solenoid coil. If continuity is not

 

 

 

 

present, replace the solenoid (See

 

 

 

 

page 24). If continuity is present,

 

 

 

 

the valve may be stuck closed.

has changed.

 

 

2. Lime build up

Inspect the dispense valve and

 

 

 

 

sprayhead for excessive lime de-

 

 

 

 

posits. Delime as required.

 

 

3. Dispense Valve

Remove dispense valve and clear

 

 

 

 

any obstructions. Rebuild or re-
