My washer is making a screeching squealing noise when the fill valves open. Water flows normally, but they make a high pitched sound while the water is running through them. I have run the manual diagnostic series and found that it happens during Codes C3 and C4 when two different solenoids engage. This corresponds to the "Select Cycle with Knob" test where it happens on Heavy Duty and Normal. The wires connecting to the solenoids are Purple and White. Is there a way to flush the valve assembly to remove build-up or possibly let it soak overnight in a vinegar bath? Water is flowing fine, it's just that SOUND! Thanks for your informative and educational site, and insight!
ANSWER Hello Marshall,
Turn off your water and start the machine. When it gets to the fill portion of the cycle, if the noise is no longer present, the water inlet valve W10372095 is defective. Before you order the new valve, check the hoses for screens and clean them if they are stopping up with mineral deposits or sedimentation from the water supply. This noise is related to the water going through the screens or the valve. It isn't a common problem but I have addressed it before and it always led me to the water inlet screens. Remember the valve has screens in it also. Note: Do not remove the screens from the valve! They must be present to prevent damage to the valve seats. If the seats are damaged, it can cause the valve to stay open and cause flood damage to your home.
