The noise filter is designed to keep DC noise from the motor from finding its way back into the house wiring and affecting other appliances, particularly cordless phones, radios, and televisions. Older models have the wire coil exposed, as shown in the photo.
	More recent models include a plastic cover over the coil for additional safety. Order part by model number and serial number.

Using an ohmmeter, check from the white connector terminal 1 (white wire) to the red connector terminal 1 (blue wire.) The resistance should be 0 ohms.

Then check from the white connector terminal 3 (black wire) to the red connector terminal 3 (brown wire.) The resistance should be 0 ohms.

If these tests pass, reconnect the white connector (the cord coming into the washer) but not the red connector (the output to the main board and the rest of the washer.)

BE AWARE that on some models, the noise filter terminals are crossed; that is, #1 input goes to #3 output, and vice versa. The test procedure is basically the same.

Plug in the machine in. Read the voltage across terminals 1 and 3 of the red (output) connector. It should be approximately 120 V_AC, the same as at the outlet.
