    Why is there no hot water in the detergent dispenser of my Dexter Laundry T-950?
    • R
      Rachel RoseSep 5, 2025
      If there's no hot water in the detergent dispenser of your Dexter Laundry Washer, check the water valve coil continuity at the terminals and replace it if there is no continuity. Remember, there is 120 VAC power (60Hz) only on for 20 seconds in the wash bath (24 VAC for 50 Hz models). Inspect the water inlet screens for blockage and clean them if necessary. Ensure that the water supply is turned on and operating. Also, check the wire harness to the valve.

    How to open a Dexter Laundry Washer door that will not open?
    • D
      dchavezSep 3, 2025
      If the door of your Dexter Laundry Washer won't open, check if the thermoactuator and its mechanism are stuck or binding. Ensure the locking thermoactuator is not receiving 24VAC during the last 1 1/2 minutes of the cycle and that the unlocking thermoactuator is receiving 24VAC during the last minute. If the timing and voltage are correct, replace the thermoactuator. Also, verify that the door rod from the mechanism to the lock assembly is long enough to allow the lock assembly to disengage; adjust the rod or the position of the mechanism if needed. Check that the door lock mechanism is not stuck closed; if it is, replace it.

    What to do if Dexter Laundry Washer starts but will not advance in the cycle?
    • R
      Robert MayerNov 23, 2025
      If your Dexter Laundry Washer starts but doesn't advance in its cycle, begin by checking the water valves to ensure they're operating. Look for the illuminated red light on the Input/Output PCB for the water valves (#5, #6, #7, #8) and confirm the board is sending 120VAC to the valve. Replace the valve if it receives 120VAC but doesn't function; otherwise, check the Input/Output PCB. Next, verify the drain valve is closing properly and check for 120VAC to the drain valve from Input/Output PCB red light #4. Replace or clean the drain valve if it receives 120VAC but doesn't close; if there's no voltage, inspect the CPU board, ribbon cable, and I/O PCB. Clear any obstructions from the fill hose or water valve screens. Ensure the water supply is turned on and working. Examine the pressure swit...

      If water comes into your Dexter Laundry Washer but the level does not rise, check the drain valve for blockage and the drain valve motor and gear train. If there is power but the drain valve does not close, replace the valve. Check for power to the drain valve; if there's no power, check the (brown/yellow) circuit for power. Also, check or replace the water valve diaphragms.

    What causes excessive vibration in Dexter Laundry Washer?
    • R
      Richard MedinaAug 28, 2025
      If your Dexter Laundry Washer experiences excessive vibration, check the strength of the mounting structure, concrete, or base, and ensure the mounting bolts are tightened. A worn drive belt or damaged pulleys can also cause vibration and noise, so inspect these components. Be sure you wash recommended load size as specified for washer model (in lb/kg). Small loads contribute to out of balance loading and increase vibration.
