TROUBLE SHOOTING GUIDE 

SYMPTOM POSSIBLE 

CAUSE 

WHAT TO 

CHECK 

REMEDY 

 
CAN'T START BREW CYCLE

 

 
1. No water. 
 
 
2. No power. 
 
 
3. Warmer switch not on 
 
 
4. Brew start switch. 
 
 
5. Timer or timer harness. 
 
 
 
6. Solenoid valve. 
 

 
1. Incoming water lines & water shut  
    off valve. 
 
2. Fuse or circuit breaker. 
    Power cord and plug connections. 
 
3. Switch is on and lighted red, 

continuity 

 
4. Switch continuity. 
    (Normally closed.) 
 
5. Wire leads to solenoid and 
    white 3-pin connector. 
 
 
6. (A) Voltage at solenoid valve  
    terminals. Start a brew cycle and  
    check for 120 volts AC. 
    (B) If voltage is present at  
    terminals, check for water at line  
    pressure on the inlet side of  
    solenoid valve. 
 

 
1. Be sure water shut off is open. 
 
 
2. Replace or reset circuit protector 
 
 
3. If warmer switch does not make and  
    break contact, replace warmer switch. 
 
4. If brew start switch does not make and  
    break contact, replace brew start switch. 
 
5. Make sure these connections are tight. If  
    so, and all else checks out OK, replace  
    timer. 
 
6. (A) If voltage is not present at terminals,  
    refer to steps 2 through 5. 
 
    (B) If voltage is present at terminals and  
    water at line pressure is present on the  
    inlet side of the solenoid, but not present  
    on the outgoing side, replace solenoid. 
 

 
NO HOT WATER 

 
1. Tank heater. 
 
 
 
 
 
 
 
 
2. Hi-limit thermostat or main 
    thermostat. 

 
1.  Check the voltage at the tank  
    heater terminals. Voltage should be 
    as indicated on the serial tag (on 
    rear of brewer.) 
 
 
 
 
 
 
2. Check the voltage between the  

VIOLET/RED wire on the tank 
element and the  incoming terminal 
(VIOLET/BLACK) on tthe hi-limit 
thermostat, then the  outgoing 
terminal (VIOLET/BLACK) on  the 
hi-limit thermostat. 

 
1. (A) If correct voltage is present at the  
    tank heater terminals and water in tank is  
    not being heated, replace the tank heater. 
    (B) If voltage is not present  at the tank 
     heater terminals refer, to step 2. 
    (C) If incorrect voltage is present at the  
    tank heater terminals, check voltage at  
    outlet. 
 
2. (A) If voltage is present on the incoming 
     terminal of the hi-limit thermostat, but  
    not on the outgoing terminal, replace the  
     hi-limit thermostat. 
    (B) Check voltage  at the terminal blocks. 

If voltage is  not present check outlet or 
circuit breaker. 

    (C) If voltage is not present on the  
    incoming terminal of the hi-limit  
    thermostat, replace the main thermostat. 
 

 
DRIPPING 

 
1. Not siphoning properly. 
 
 
 
2. Solenoid valve not seating  
    properly. 
 
 
 
 

 
1. Water should flow freely from the 
    sprayhead. 
 
 
2. Solenoid valve assembly. 
 
 
 
 
 

 
1. (A) Clean sprayhead holes. 
    (B) Check tightness of sprayhead tube. 
    (C) See "DELIMING" , Page 5. 
 
2.  Be sure spring is in place and any  
    particles  are cleaned from valve seat. If 
    valve seat is  worn or mutilated, replace  
    solenoid valve. 
 
 

 
STEAMING OR SPITTING 
AROUND FUNNEL 

 
1. Main thermostat. 
 
 
 
2. High altitude. 

 
1. Thermostat points stuck or out of 
    calibration. 
 
 
2. Located above 5,000 feet. 

 
1. (A) Adjust  thermostat. 
    (B) Thermostat should be calibrated or 
    replaced. 
 
2. See "INSTALLATION 
    INSTRUCTIONS", Page 4.. 
 

 
WATER KEEPS RUNNING 

 
1. Solenoid valve. 
 
2. Start switch. 
 
 
3. Timer 
 

 
1. Refer to "DRIPPING", Step 1. 
 
2. Remove wires from switch and  
    check continuity. 
 
3. Solid state timers are not  
    repairable. If timer will not shut 
    off, replace timer. 
 

 
1. Refer to "DRIPPING", Step 1. 
 
2. If start switch does not make and break  
    contact, switch should be replaced. 
 
3. Replace timer.
