Electrical Shock Hazard
Disconnect power before servicing.
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
PD KEYPAD TESTING
1. Unplug washer or disconnect power.
2. Set the ohmmeter to the R X 1 scale. Set
digital ohmmeters to lowest scale.
3. Using a ribbon connector test board like the
one shown below; touch the ohmmeter test
leads to the contacts listed. Press the button
listed for each pair of contacts. The meter
should indicate continuity (0 Ω). If the meter
indicates an open circuit (infinite Ω), replace
the membrane switch.
NOTE: Due to variablility in contacts within the
membrane switches, full continuity may not be
achieved. Look for changes of resistance on
the meter.
