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 |
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. | 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. |

| 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. |
