WFMC Service Tips – Test Program (2B): Module Fault Codes (Test1)
Test P1:ERRORS / P:01 (Viewing control module fault codes) – Start & end test P1
(WFMC6400) / (P:01) (WFMC3200) by pushing Start/Pause button. Scroll through list of fault codes
by pushing Spin Selection (WFMC3200) or Menu (WFMC6400) buttons.
• WFMC3200 display alternates between fault code (e.g. E:01) & when fault occurred on in last 8
washes (e.g. : C:00) – shows C:00 if fault didn’t occur.
• WFMC6400 display shows fault code & when fault occurred on in last 8 washes (e.g. 0 – Er:01)
