Aquastop failure - float switch under the unit

From Tech Sheet W11472611, p.23:

1.Check float switch under machine, empty any water from catchment tray, check for water leaks or oversudsing.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
