Agitate Slow Test:

Upon entering this test, AS will be displayed on the DSSD and the washer will begin to agitate at 30

strokes per minute. The washer shall stop agitation as the test is exited.

Agitate Fast Test:

Upon entering this test, AF will be displayed on the DSSD and the washer will begin to agitate at 155

strokes per minute. The washer shall stop agitation as the test is exited.

Pump Test:

Upon entering this test, the pump will activate and a P, along with the pump current in tenths of amps

will be displayed on the DSSD. For example, if the pump current is 0.9 amps, the washer shall display

P09 on the DSSD.

Spin Slow Test:

Upon entering this test, SS will be displayed on the DSSD and the washer will begin to spin at 150 rpm.

If the START pad is pressed during this test, the spin rpm, as indicated from the speed sensor, will be

displayed on the DSSD.

Spin Fast Test:

Upon entering this test, SF will be displayed on the DSSD and the washer will begin to spin at 850 rpm.

If the START pad is pressed during this test, the spin rpm, as indicated from the speed sensor, will be

displayed on the DSSD.

Inverter Test:

Upon entering this test, SEr will be displayed on the DSSD. Power will be applied to the inverter, and

test signals will be sent on the inverter communication lines to provide a means to isolate a Power/

Communication Error. If the START pad is pressed during this test, the washer will cycle the inverter

communication lines (see figure below). Each time you touch START, you should toggle between a

positive and negative voltage that should read greater than 1 volt.

Accelerometer Test:

This test performs the signal integrity check, and displays vertical and radial acceleration on the DSSD.

The washer will display the radial peak-to-peak acceleration upon entry, and will toggle between

displaying radial acceleration and vertical acceleration each time the START pad is pressed.

The washer shall display radial acceleration in tenths of G’s with a preceding r, for radial, on the DSSD.

For example, a radial acceleration of 0.8 g’s would be displayed as r08. If the radial acceleration fails

the signal integrity check, the washer shall display rbd (radial bad).

The washer shall display the vertical acceleration in tenths of G’s with a preceding u, for up, on the

DSSD. For example, a vertical acceleration of 0.8 g’s would display u08. If the vertical acceleration

fails the signal integrity check, the washer shall display ubd, for up bad.

Note: See Accelerometer for instruction on performing this test.
