WHIRLPOOL CABRIO TOPLOADING WASHING MACHINE MODEL WTW7300DW1

I became shocked when running a Washing Machine. The washer is a Whirlpool Cabrio model WTW7300DW1 and was manufactured in 2017. The electrical shock occurred when I touched the cold-water supply hose fitting connected to the washer and the washer’s rear panel. The voltage difference between the hose fitting and panel was measured to be 84 VDC. During a wash cycles, up to 160 VDC difference was measured between the hose fitting and rear panel. The stray current was found to emanate from the thermistor in the water valve and travel through the water in the water valve assembly. When the thermistor power was disconnected, the voltage difference between the rear panel and water supply hose fitting was measured to be approximately 0 VDC. This testing demonstrates that a failure within the thermistor housing has allowed water penetration into the thermistor and the passage of leakage current to the water supply hose fitting. This failure not only represents a shock hazard, but can also result in rapid corrosion and fracturing of the water supply hose fitting itself.
