WFMC Service Tips – Test Program (2C): Motor Control Fault Codes
(Test1)
Test P1:ERRORS / P:01 (Viewing motor control fault codes) – Start & end test P1 by pushing Start/Pause button. Scroll through list of (18) fault codes by pushing Spin Selection (WFMC3200) or Menu (WFMC6400) buttons.
•WFMC3200 display alternates between fault code (e.g. d:01) & when fault occurred on in last 16 washes (e.g. : C:00) – shows C:00 if fault didn’t occur.
•WFMC6400 display shows fault code & when fault occurred on in last 16 washes (e.g. 0 – Er:01)
Last 16 fault codes are
stored & display!
HINT: # of faults reads “0” for faults which didn’t occur. Look at # of faults, not error #, to see if faults occurred – scroll thru all faults to check if any occurred.
