Why is my Dexter Laundry T-400 On-Premise Washer vibrating excessively?
- A
  Amber MooreAug 22, 2025
  Excessive vibration in your Dexter Laundry Washer can stem from several issues. Check the strength of the mounting structure (concrete or base) and ensure mounting bolts are tightened. A worn drive belt can also cause vibration and noise, so inspect its condition. Also, small loads can contribute to out-of-balance loading, increasing vibration.

What to do if the door on my Dexter Laundry T-400 On-Premise won't lock?

  If the door on your Dexter Laundry Washer isn't locking, start by checking the display for a fault code, specifically F1, and follow the tests described in the fault code section. Then, check if the door locking mechanism is receiving 120VAC 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's no continuity.

  If the door of your Dexter Laundry Washer won't open, start by checking if the thermoactuator(s) and its mechanism are stuck or binding. Ensure the locking thermoactuator isn't receiving 120VAC during the last 1 1/2 minutes of the cycle and that the unlocking thermoactuator is receiving 120VAC during the last minute. If the thermoactuators don't receive voltage at the correct times, change the timer. If 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; if it is, replace it.

  If hot water isn't entering the tub of your Dexter Laundry Washer during the wash cycle, check the water valve coil for continuity at the terminals and replace it if there's no continuity. Also, check for 120 V power from the main relay PCB. Inspect the water inlet screens for blockages and clean them if necessary. Ensure that the water is turned on and operating. Check the black or white wires at the Molex plug on the PCB at the main controller and at the relay PCB. Finally, check the pressure switch continuity between terminals; if there's no continuity, check the pressure switch hose for obstructions, and if the hose is okay, change the pressure switch.

  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's no continuity. Note that 120 V power is only on for 20 seconds in the wash bath. Inspect the water inlet screens for blockage and clean the screens if necessary. Ensure that water is turned on and operating. Check the black & white wire harness (P-20).

What should I do if water comes in, but the level doesn't rise in my Dexter Laundry T-400 On-Premise?
- L
  Lisa TuckerSep 9, 2025
  If water enters your Dexter Laundry Washer but the level doesn't rise, check for drain valve blockages and inspect 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 no power to drain valve, check (brn/yel) circuit for power. Check the black and white wires at the molex plug on the main PCB controller and at the main relay PCB.
