Test P12: UPDATE / P:12 (Update programming) --
This test cannot be used presently. If selected, it can only be
exited by turning the washer off using the selector knob.
NOTE: On WFMC32/WFXD52, displays alternates from “P:13” to
“63”, “88” or “177”, depending on water level (below or at heating
level).
HINT: Test runs until max. water level reached or is stopped by pressing
Menu button. To save time with Test P13, press Menu to stop test when
all valves have been checked. Run Test P15 to drain washer if needed.
HINT: If Start/Pause light doesn’t come on for some tests, door is
open. Turn off washer, then close door.

WFMC64/WFXD84, push Start/Pause button to check each valve:
• At start of test, valve 1 (cold) is tested.
•Push Start/Pause button again to check valve 2 (cold).
•Push Start/Pause button again to check valves 1 + 2 (dual cold).
•Push Start/Pause button again to check valve 3 (hot).
• Pushing Start/Pause button again checks valve 1 again.
•Push Menu button to exit test.
HINT: Water level symbols change as follows (e.g. test P13):
• WFMC64/WFXD84 -- from N
0
(below heating level) to N
H
(heating level) to N
D
(door locked level).
• WFMC32/WFXD52 -- from 63 (below heating level) to 88
(heating level) to 177 (door locked level).
