C500 AP Air Pot Coffee Brewer

TROUBLE SHOOTING CONTINUED:

POSSIBLE CAUSE

SOLUTION

4. Defective or burned out

Pull wire out of probe terminal. With a Volt meter, check voltage at the

water level control

water inlet coil terminals. This should read 110-120 volts. If no voltage is

board

present, check Liquid Level Control board. Make sure the L.L.C. board is

 

energized on terminals 2 & 3. The L.L.C. board is grounded to the chas-

 

sis of the machine by contacting the board to the mounting bracket. Make

 

sure board is grounded here. Check for loose connections at terminals.

 

When the water level control board fails to energize the water inlet valve,

 

the board should be replaced

 

 

PROBLEM: WATER HEATING TANK OVERFLOWING.

POSSIBLE CAUSE

SOLUTION

5.

Defective water inlet

Turn power off and observe water level. If water continues to flow in,

 

valve

valve is leaking; clean or replace valve.

 

 

 

6.

Probe limed up

Pull wire off from probe terminal. Touch the body of the heating tank

 

 

with the end of this wire. If water stops, try cleaning the probe. Probe

 

 

may have to be replaced.

 

 

 

7.

Non-grounded or loose

Liquid level control board must be securely grounded. Check for loose

 

terminal connections at

connections at the terminals. Check for voltage at the inlet valve termi-

 

liquid level control

nals. If there is voltage present at the inlet valve terminals, replace the

 

board

L.L.C. board.

 

 

PROBLEM: WATER IN TANK DOES NOT GET HOT OR WATER TEMPERATURE TOO LOW

 

 

POSSIBLE CAUSE

SOLUTION

8. Thermostat turned OFF

Check thermostat to make sure it is in the ON position.

 

 

9. Defective thermostat

Replace thermostat.

 

 

10. Burned out heating

Check element for continuity and/or check with clamp ammeter. This

 

element

should show a reading of approximately 15 amps. If no power is going

 

 

through element, replace it.

 

 

PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD.

 

 

 

 

POSSIBLE CAUSE

SOLUTION

11. Water level is too low

Check water level in tank. If water is not flowing into the tank, review

 

in heating tank

steps 1 thru 4, on previous page.

 

 

12. Defective brew switch

With the power off, check the continuity between terminal 4B & 5B.

 

 

When the switch is pressed, there should be solid continuity between

 

 

these two terminals. If not, replace the switch.
