PROBLEM

 

PROBABLE CAUSE

Brew cycle will not start

 

1. Display flashing

2. No water

3. No power or incorrect voltage to the brewer

4. ON/OFF switch not in the "ON" position

5. Low water temperature (Brew lockout is enabled)

6. Water not touching refill probe inside tank

7. Switch panel

REMEDY

Brewer has shut down due to mal- function (See Diagnostic Chart in manual, Page 20, or under top lid of brewer).

Water lines and valves to the brewer must be open.

Check for voltage across the termi- nals at the terminal block.

The indicator lamp must be lit

Allow brewer to heat until ready lamp is lit, or disable the brew lock- out feature. (See page 8)

Press ON/OFF switch (indicator must be lit). Brewer will refill until water touches probe inside tank. Water must be in contact with refill probe before brew cycle will start.

Disconnect the brewer from the power source. Disconnect the rib- bon connector from the control board. Check for continuity between pins 1 & 2 (An arrow on the connec- tor indicates pin 1). No continuity should be present. Press the BREW switch. Continuity should be present for as long as the switch is held down. If no continuity is present, replace the switch membrane de- cal.
