Diagnostics
Service Menu (Pics 2 through 6)
Warning Status / Fault Status. Warning Status reflects non-fatal faults that can be corrected by user intervention. In the instance of No Hot Water, I had the water heater set at a lower temp than the machine wanted so it complained.

Fault Status reports serious errors that require service.
Machine Status displays some basic operational information --
Size = tub/bowl size (MM diameter)
HVDC = motor board high voltage output
WL = water level sensor reading
T = water temperature sensor reading
Target = inlet temperature that the machine wants to attain
Hot solenoid, Cold solenoid, Detergent solenoid, Fabric softener solenoid, Pump, Bleach solenoid are to manually operate those components. Detergent and Softener require hot or cold (or both) be turned on first. Bleach feeds separately directly from the cold side. Pump selects Drain, Recirculate, or Off.
Photo #6 is a special screen that doesn't display except via a special key procedure. It reports a myriad of parameters during machine operation, some of which I don't understand.
Disp is the display board software version.
MC is the motor control board software version.
RPM is the motor rotor RPM reading.
OB probably is whether off-balance is triggered.
WL is the water level sensor reading.
BF is Bowl Float, the water level at which the bowl sensed as floated.
Fill is the water level the machine wants.
Idle is the current cycle function -- agitate/wash, rinse, spin, etc. -- not sure exactly what all it says there.
Time I think is elapsed cycle time, although it doesn't begin counting immediately at the start.
To Go is remaining time to cycle finish.
Mixed is the agitation profile (various terms are involved).
Topup is related to water level control.
The other parameters, I don't know what they mean but some of them change during water level sensing and during agitation.
Photo #7 Control Option
Hot Tub is a flag that is set on a warm or hot wash fill, clears after a cold rinse. Spin speed is restricted to medium (670 RPM) if Hot Tub is flagged. This function allows it to be manually set or cleared for diagnostic purposes.
Restart allows the machine to "restart"/retry a failed function in an attempt to automatically recover from a fault. It normally should be enabled and the machine will "restart" numerous times until it gives up and throws a fault, but can be disabled to assist with troubleshooting a problem more quickly.
Recycle is a diagnostic tool that has the machine run a cycle repeatedly until manually shut off to aid in confirming an erratic problem.
Photo #8 Development Data only appears via a special key combination, and the machine must be disconnected from power to turn it off after it's selected. I have no idea what the parameters indicate.
