      Daniel ArcherSep 2, 2025
      If you notice water leaking around the loading door of your Dexter Laundry Washer, consider these solutions: * **Door Adjustment:** The door may need adjustment due to wear or abuse. Check the tightness around the perimeter using a dollar bill. Adjust left to right tightness using shims at the door lock or hinge side. Center the gasket to the tub opening before tightening the door to hinge bolts. Chalk may help show the contact point with the tub front. If the gasket is deformed, worn, or damaged, replace it.
