Fault Codes (Test 1)
Test P1:ERRORS / P:01 (Viewing motor control fault codes) -- Start & end test P1 by
pushing Start/Pause button. Scroll through all fault codes by pushing Spin Selection (WFMC32/33/53) or
Menu (WFMC64/84) buttons. If motor fault codes can’t be accessed, no faults occurred – control module
fault codes will show repeatedly.
• WFMC32/33/53 displays 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.
• WFMC64/84 displays show fault code & when fault occurred in last 16 washes (e.g. 0 - dr:01).

show if none occurred -- # of
faults reads “0” for faults which
didn’t occur. Scroll thru all
faults and look at # of faults to
see which faults occurred.
NOTE
: Fault codes stored in
motor control can’t
be cleared .
HINT
