Why has my Dishwasher Seal come loose?

• Wear and Tear – Over time, the rubber or silicone seal can deteriorate due to frequent use and exposure to hot water and detergents, causing it to come loose or develop gaps.
• Accidental Damage – Poking, prodding, or accidentally catching the seal with utensils or dishes can cause it to become dislodged or damaged.
• Excessive Heat – High-temperature wash cycles and drying can accelerate the degradation of the seal material, leading to it coming loose.
• Chemical Reactions – Certain dishwasher detergents may contain harsh chemicals that can weaken or corrode the seal over time.

How to Replace a Dishwasher Door Seal: A Step-By-Step Guide

Before you get started, please ensure your dishwasher is unplugged or disconnected from its power source for your safety.

1. Order a Replacement Seal – If your door seal has perished, your first step is to purchase a replacement dishwasher door seal that matches your dishwasher’s make and model.
2. Prepare Your Workspace – Lay down a towel or mat to catch any water or debris that may come out during the process. You may want to wear gloves to protect your hands.
3. Open the Dishwasher Door – Fully open the dishwasher door to access the seal. Take note of how the existing seal is positioned and any clips or retainers that hold it in place.
4. Remove the Old Seal – Gently peel or pull the old seal away from the dishwasher door. Start at one corner and work your way around. Be careful not to damage the door or any surrounding components.
5. Clean the Door – Use a mild detergent and warm water to clean the area where the old seal was attached. Ensure there is no debris, residue, or old adhesive left behind.
6. Prepare the New Seal – Unpack the new seal and check it for any manufacturer instructions or guidelines. Sometimes, seals come with adhesive backing, which you may need to activate.
7. Install the New Seal – Begin attaching the new seal at one corner of the dishwasher door. Press it firmly into place, following the path of the old seal. Ensure it fits snugly and securely without any gaps.
8. Secure with Clips or Retainers – If your dishwasher has clips or retainers to hold the seal in place, make sure to reattach them according to the manufacturer’s instructions.
9. Check for Proper Fit – Inspect the seal to ensure it is properly seated and snug against the door. There should be no visible gaps.
10. Close the Dishwasher Door – Gently close the dishwasher door to allow the seal to settle in its proper position.
