Firmware upload failed / UPL ERR codes (UECM CMY, UEEF EFFECT, UELD LED DRV, UEPN PAN, UETL TILT, UEZF Z/F)
Likely cause: Each UExx code names the sub-processor whose image failed to write.

Fixture will not power up, dims oddly, or shows undervoltage behavior on a 100-120 V circuit
Likely cause: Unlike some smaller MAC fixtures, the Ultra Wash's PSU is specified for 200-240 V only, so a 120 V feed leaves it under-powered.
