TROUBLE SHOOTING GUIDE
SYMPTOM
POSSIBLE CAUSE
WHAT TO CHECK
REMEDY
IRREGULAR YIELD
1. Not siphoning properly.
2. Control board/timer.
3. Fluctuating water pressure.
4. Solenoid valve.
5. Flow washer.
6. Micro switch.
1. Refer to "DRIPPING" Step 1.
2. Timer consistency. Time several
brew cycles.
3. Water pressure.
4. Refer to "DRIPPING" Step 2.
5. Possible lime build up in flow
washer or flow control.
6. Refer to "WATER KEEPS
RUNNING" Step 4.
1. Refer to "DRIPPING" Step 1.
2. If times are irregular replace board.
3. If pressure fluctuates 10-20 PSI during
operation of brew cycle, add a pressure
regulator to inlet side of brewer, set to
lowest pressure level registered. adjust
timer to yield correct water level.
4. Refer to "DRIPPING" Step 2.
5. (A) Replace flow washer and clean
screen. Screen is located inside
solenoid.
(B) Flow washer must be .250 GPM.
6. Refer to "WATER KEEPS RUNNING"
Step 4.
DRY COFFEE REMAINING
IN BREW BASKET AFTER
BREWING
1. Filters.
2. Not siphoning properly.
3. Improper loading of the brew
basket.
1. Are correct filters being used.
2. Refer to "DRIPPING", Step 1.
3. Filter and coffee in brew basket.

2. Refer to "DRIPPING" Step 1.
3. Filter should be centered in the brew
basket and coffee bed should be level.
WEAK COFFEE
1. Filters.
2. Low water temperature.
3. Not siphoning properly.
4. Improper loading of brew
basket.
5. Missing sprayhead.
1. Are correct filters being used.
2. Check water temperature. Refer
to installation instructions.
3. Refer to "DRIPPING" Step 1.
4. Filter and coffee in brew basket.
5. Check for sprayhead.
1. Insert correct filter into brew basket.
2. Adjust thermostat control knob to
obtain correct water temperature.
3. Refer to "DRIPPING" Step 1.
4. Filter should be centered in brew
basket and coffee bed should be level.

SOLENOID CHATTER OR
HOWLING
1. Brewer connected to hot water
line.
2. Vibration.
3. High water pressure.
4. Water hammer.
5. 60 Cycle vibration.
1. Incoming water line.
2. If brewer is on a metal stand or
counter, neither the bottom pan nor
copper tubing to the brewer should
touch the counter.
3. Water pressure on incoming
line.
4. Incoming plumbing.
5. Screws on solenoid valve.
1. Should be connected to cold water
line.
2. Adjust as necessary.
3. If water pressure is over 90 PSI install
a pressure regulator and adjust to 50
PSI.
4. This is not the fault of the brewer and
can usually be corrected by rearranging
some plumbing or adding an air chamber
to the incoming water line.
5. Screws should be tight. Tighten as
required.
COLD WARMER STATION
1. Warmer - defective.
2. Warmer On/Off switch.
3. Bad harness.
1. Voltage at warmer terminals
should be 120 V ac.
2. If voltage is not present on
warmer terminals, check continuity
of the switch.
3. Check connections between
harness and switch, and between
switch and warmer.
1. If voltage is present on terminals of
warmer element, but warmer will not
heat, replace the element.
2. If switch does not make and break
continuity (between terminals 1 and 2)
when turned on and off, replace switch.
3. All connections should be tight.

required.
FAUCET FLOW SLOW
1. Entrapped air in line.
2. Faucet clogging.
