    What to do if hot water does not enter the tub in wash cycle of my Dexter Laundry T-650?
    • C
      Christine JohnsonSep 2, 2025
      If hot water isn't entering the tub during the wash cycle of your Dexter Laundry Washer, start by checking the water valve coil for continuity at the terminals and replace it if there's no continuity. Also, check for 24 VAC (50 Hz) power from the main relay PCB. Inspect the water inlet screens for blockage and clean them if necessary. Ensure that the water supply is turned on and operating correctly. Finally, check the black and white wire at the Molex plug on the main PCB controller P21 connection and at the PCB relay board P20 connection, and examine the pressure switch continuity between terminal contacts. If no continuity, check the pressure switch hose for obstruction. If the hose is okay then change the pressure switch.

    How to fix water leakage around the loading door of my Dexter Laundry Washer?
    • R
      Robert DavisSep 4, 2025
      If you're experiencing water leakage around the loading door of your Dexter Laundry Washer, the door may need adjustment due to wear. Check the tightness around the door's perimeter using a dollar bill. Adjust the left-to-right tightness using shims at the door lock or hinge side. Ensure the gasket is centered to the tub opening before tightening the door to hinge bolts. Chalk may be used on the tub front to show the point of contact with the tub. If the gasket is deformed, worn, or damaged, replace it.

    What to do if my Dexter Laundry T-650 Washer door will not open?
    • J
      Joshua MaysSep 5, 2025
      If the door of your Dexter Laundry Washer won't open, check to see if the thermoactuator and its mechanism are stuck or binding, preventing the door lock motor from opening. Ensure that the locking thermoactuator isn't receiving 24 VAC (50 Hz) during the last 1 1/2 minutes of the cycle and that the unlocking thermoactuator is receiving 24 VAC (50 Hz) during the last minute of the cycle. If the thermoactuators do not receive voltage at the correct times, change the PCB relay board. If the timing and voltage are correct, replace the thermoactuator.

    What to do if water comes in but the level does not rise in my Dexter Laundry T-650?
    • P
      Patrick PetersonSep 5, 2025
      If water enters your Dexter Laundry Washer but the level doesn't rise, check the drain valve for blockages and inspect the drain valve motor and gear train. If there is power to the valve but the drain valve does not close, replace the drain valve and motor. Check for power to the drain valve; if there's no power, check the (brn/yel) wire at the PCB relay board. If there's no power on the (brn/yel) wire when the washer is in a wash cycle, replace the relay board. Also, check the black and white wire at the Molex plug on the main PCB controller P21 connection and at the PCB relay board P20 connection.

    • E
      Erika GreeneSep 6, 2025
      If your Dexter Laundry Washer tumbles in only one direction, refer to the DISPLAYED WASHER FAULTS section for more information. Also, inspect the yellow enable wires from the main relay PCB and at the VFD.

    What does it mean if my Dexter Laundry T-650 Washer machine does not stop?
    • K
      Katherine MillerSep 7, 2025
      If your Dexter Laundry Washer machine does not stop, this could be due to the main PCB, which controls the cycle time and end of cycle. Also, check the braking resistors for continuity and verify the ohms resistance at the braking resistors with the wires removed.
