    Why Dexter Laundry T-950 machine does not start?
    • C
      Chad MontgomerySep 9, 2025
      If your Dexter Laundry Washer isn't starting, several factors could be at play. Begin by examining the power supply, checking circuit breakers, voltage, power leads, and connections. Ensure the front display LED is lit. Next, verify the door switch for continuity when closed; adjust or replace if necessary. Inspect the control breaker or fuse for continuity and replace if needed. Check the control transformer's voltage output. Ensure all wire connections on the PCB board and relay PCB are secure. Also, confirm that the door lock mechanism is receiving the correct voltage after pressing the start button. Lastly, inspect the data cable phone type connectors between the PCB and VFD, ensuring they are properly plugged in after removing power.

    What to do if hot water does not enter tub in wash for Dexter Laundry Washer?
    • R
      Richard RodriguezSep 9, 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 its terminals and ensure it's receiving the correct voltage from the main relay PCB. Replace the coil if there's no continuity. Inspect the water inlet screens for any blockages and clean them if necessary. Confirm that the water supply is turned on and functioning correctly. Check the black and white wires at the Molex plug on the PCB at the main controller and at the relay PCB. Also, check the pressure switch continuity between terminals; if there's no continuity, inspect the pressure switch hose for obstructions and replace the switch if the hose is clear.

      If the door on your Dexter Laundry Washer isn't locking, check the display for any fault codes. Specifically, if F1 is displayed, consult the fault code section for further instructions. Verify that the door locking mechanism is receiving the appropriate voltage from the main relay PCB; if it is, consider replacing the mechanism. Also, check the door latch switch for continuity when the door is closed; adjust or replace the switch if there is no continuity.

    What to do if Dexter Laundry T-950 Washer door will not open?
    • J
      Jasmin RodriguezSep 12, 2025
      If the door of your Dexter Laundry Washer won't open, examine the thermoactuator and its mechanism for any sticking or binding that may prevent the door lock mechanism from opening. Ensure the locking thermoactuator isn't receiving 120VAC (60 Hz) or 24 VAC (50 Hz) during the last 1 1/2 minutes of the cycle, and that the unlocking thermoactuator is receiving the correct voltage during the last minute. If the timing and voltage are correct, replace the thermoactuator. Also, check the door rod from the mechanism to the lock assembly to ensure it's long enough to allow the lock assembly to disengage; adjust the rod if necessary. Finally, check that the door lock mechanism isn't stuck closed; replace it if it is.

      Kelsey AllenSep 12, 2025
      To address excessive vibration in your Dexter Laundry Washer, check the strength of the mounting structure (concrete or base) and ensure the mounting bolts are tightened. A worn drive belt can also cause vibration and noise, so inspect and replace if necessary. Keep in mind that small loads can contribute to out-of-balance loading, increasing vibration.

      To troubleshoot why your Dexter Laundry Washer isn't turning, begin by checking the VFD (Variable Frequency Drive). Remove the inspection panel and note any numbers or letters displayed. If there's no display, turn off the power to the machine at the breaker for two minutes, then turn it back on to reset. If the issue persists and there's still no display, consider replacing the VFD.
