- replace the NIPPLE-FILL AND DRAIN (11DV) (Ref. AMM TASK 30-72-52-000-001) and (Ref. AMM TASK 30-72-52-400-001).
(2) If the fault continues:
- do a check for the subsequent signals: 115VAC at TERMINAL BLOCK 7510VT connector 6/F, GND at TERMINAL BLOCK 7510VT connector 6/A.
(a) If one signal is not OK:
- do a check and repair the related wiring (Ref. ASM 30-72/01).

1. At the potable-water service At the potable-water service panel panel (inboard side): (outboard side):
- apply cooling spray on and - examine that the heated fill/drain around the thermostat 14DV for nipple 13DV becomes warm. at least 10 seconds.
4. Fault Isolation
_______________
A. If the overflow nipple 13DV stayes cold:
- replace the THERMOSTAT-OVERFLOW NIPPLE (14DV) (Ref. AMM TASK 30-72-52-000-001) and (Ref. AMM TASK 30-72-52-400-001).
(1) If the fault continues:
- replace the NIPPLE-OVERFLOW (13DV) (Ref. AMM TASK 30-72-52-000-001) and (Ref. AMM TASK 30-72-52-400-001).
(a) If the fault continues:
- check for the subsequent signals at the terminal block 7510VT7:
- 115VAC at 7510VT7/F;
- GND at 7510VT7/A.
1 If one signal is missing:
_ - check and repair the wiring (Ref. ASM 30-72/01).
B. Do the test as given in Para. 3.C.
