(2) Make sure that the potable water system is pressurized (Ref. AMM TASK 38-10-00-614-001).
4. Fault Isolation
_______________
A. If you cannot pressurize the potable water system:
- do a check and make sure that no air flows from the VALVE-OVERFLOW (8MP).
(1) If the over-flow valve 8MP is not closed:
- do a check and adjust the Fill limit switch 5MP as necessary.

(2) If the fault continues:
- do a check and make sure that the Control cable 3260MM operates freely, if not replace (Ref. AMM TASK 38-14-48-000-001) and (Ref. AMM TASK 38-14-48-400-001).
(3) If the fault continues:
- replace the VALVE-OVERFLOW (8MP), (Ref. AMM TASK 38-14-44-000-001) and (Ref. AMM TASK 38-14-44-400-001).
(4) If the fault continues:
- do a check and repair the aircraft wiring between the: CB 1MP and the connector A/C VALVE-OVERFLOW (8MP), (Ref. ASM 38-14/00).
5. Close-up
________
A. After the subsequent flight, make sure that the fault does not continue.

4. Fault Isolation
_______________
A. If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
B. If there is no quantity indication (no LED illumination/quantity indicator) on the FORWARD ATTENDANT PANEL 120RH/SERVICE PANEL 2023VU: - open and close the circuit breaker 1MA.
(1) If the fault continues:
- do a check of the doorlimit switch 5MA, (Ref. AMM TASK 38-13-00-710-002).
(2) If the fault continues:
- replace the door limit switch 5MA (Ref. AMM TASK 38-13-16-000-001) and (Ref. AMM TASK 38-13-16-400-001).
(3) If the fault continues:
- replace the GAUGE-CONTENTS (6MA), (Ref. AMM TASK 38-13-21-000-001) and (Ref. AMM TASK 38-13-21-400-001).
(4) If the fault continues:
- replace the XMTR-QUANTITY (3MA), (Ref. AMM TASK 38-13-11-000-001) and (Ref. AMM TASK 38-13-11-400-001).
(5) If the fault continues:
- do a check and repair the aircraft wiring between the: CB 1MA and the connector A/C XMTR-QUANTITY (3MA), (Ref. ASM 38-13/00).
