How to Replace a Dishwasher Heating Element for Better Drying Performance

A dishwasher’s heating element plays a vital role in both washing and drying your dishes. It helps heat the water to the appropriate temperature during the wash cycle and dries your dishes after they’ve been washed. If you’ve noticed that your dishes aren't drying as well as they used to, or if your dishwasher isn’t heating the water properly, it might be time to replace the heating element. Here’s a step-by-step guide to help you replace the heating element and restore your dishwasher’s drying performance.

What You’ll Need:

• Replacement heating element (check your dishwasher model for compatibility)
• Screwdriver
• Multimeter (for testing the old element)
• Pliers (optional)
• Towel or sponge (to soak up water)

Step 1: Unplug the Dishwasher

Before you start any repair, always make sure the dishwasher is completely unplugged from the power source. If you cannot unplug it easily, turn off the circuit breaker that powers the dishwasher to avoid any risk of electric shock.

Step 2: Remove the Bottom Rack and Dish Tray

Take out the bottom rack and the dish tray to give yourself ample room to access the heating element. You may also want to soak up any remaining water in the dishwasher with a towel or sponge to prevent any spills when you’re working.

Step 3: Locate the Heating Element

The heating element is typically located at the bottom of the dishwasher, running along the edges. It will look like a metal coil or a flat strip with two terminals at either end. In most dishwashers, it’s easy to spot, but it can vary by model, so check your manual if you’re having trouble.

Step 4: Disconnect the Heating Element

Using your screwdriver, remove any screws that are securing the heating element in place. Some models may require you to remove the dishwasher’s lower spray arm or other components to access the element. Carefully lift the heating element from its position.

Before completely removing the element, you’ll need to disconnect the electrical terminals. You may need pliers to release the wires from the terminals. Take note of where each wire is connected, as you'll need to reconnect them to the new heating element later.

Step 5: Test the Old Heating Element (Optional)

If you’re unsure whether the heating element is the issue, you can test it with a multimeter. Set the multimeter to measure resistance (ohms) and place the probes on each terminal of the heating element. If the multimeter reads zero or infinite resistance, the element is faulty and needs to be replaced.

Step 6: Install the New Heating Element

Take your new heating element and connect it to the electrical terminals, ensuring the connections are secure. Position the element in the same location as the old one and secure it with screws. If you removed the spray arm or other parts earlier, be sure to reinstall them.

Step 7: Reconnect Power

Once the new heating element is installed and secured, plug the dishwasher back in or turn the circuit breaker back on. Before running a full cycle, double-check that the element is properly connected and that there are no loose parts.

Step 8: Test the Dishwasher

Run a short cycle on your dishwasher to test the new heating element. Check the water temperature during the wash cycle (you can use a thermometer to measure it) and the drying performance at the end of the cycle. If the water is hot and your dishes are drying properly, the new element is working as expected.

Tips for Maintaining Your Heating Element:

• Regular Cleaning: Over time, mineral deposits and food particles can accumulate on the heating element. Clean it regularly with a vinegar solution to maintain its efficiency.
• Check for Blockages: Ensure the heating element isn’t obstructed by dishes or debris during the cycle, as this can interfere with its ability to heat properly.
• Replace Damaged Elements Promptly: If you notice any cracks or breaks in the heating element, replace it immediately to avoid further damage to your dishwasher.

Conclusion

Replacing the heating element in your dishwasher is an easy repair that can dramatically improve the drying performance of your machine. By following these simple steps, you can restore your dishwasher's efficiency and ensure your dishes come out clean and dry every time. If you’re not comfortable performing the repair yourself, it’s always a good idea to contact a professional technician to handle the replacement. With a new heating element in place, you’ll notice better drying performance and fewer issues with water temperature during cycles.
