Troubleshooting the Moisture Sensor Circuit

NOTE: Troubleshooting must be done with the machine basket empty.

52.Troubleshooting at the Control

1. On the control board, unplug the harness from header H5 (Refer to Figure 9).

2. Insert ohm meter probes into pins 1 and 2 of the harness. If the metered value is infinite resistance, open load

(OL), proceed to step 3. If not, proceed to Paragraph 53.

3. Create a direct short between machine basket and moisture sensing baffle/ground using test jumper

(Refer to Figure 10). If metered value is less than 1 ohm, circuit is functioning properly; double-check

machine configuration and cycle programming. If 1 ohm or greater, proceed to Paragraph 53.
