How to Fix a Dishwasher that Melts Plastic
Particular troubleshooting procedures must be followed to fix a dishwasher that melts plastic. Here are the recommended fixes:
1. Inspect Plastic Items Before Loading
Before running the dishwasher, it is crucial to thoroughly inspect all plastic items to ensure they are free from any scratches, cracks, or signs of wear. Even minor damage can make plastic items more susceptible to melting or warping in the dishwasher’s high-heat environment.
Carefully examine each plastic item, paying particular attention to areas that come into contact with hot water or steam.
If any damage is found, it is recommended to refrain from using these items in the dishwasher to prevent further deterioration and potential melting. Instead, consider hand washing these damaged plastic items to ensure their longevity and avoid any safety concerns.
2. Use Dishwasher-safe Plastics
Ensuring that all plastics are expressly labeled as dishwasher-safe and heat-resistant is crucial to reduce the possibility of plastic goods melting.
When selecting plastic items for dishwasher use, look for dishwasher-safe symbols or labels on the packaging or the item itself. These symbols indicate that the plastic can withstand the dishwasher’s high temperatures without melting or releasing harmful chemicals.
Using plastics that are not labeled as dishwasher-safe can warp, melt, or even release toxic substances during the dishwasher’s cycles.
By exclusively choosing dishwasher-safe plastics, you can ensure the longevity of your plastic items and maintain a safe dishwasher environment.
3. Proper Loading and Positioning
Following the manufacturer’s guidelines for loading and positioning them is crucial to prevent plastic items from melting in the dishwasher.
Refer to the dishwasher’s user manual or instructions provided by the manufacturer to understand the recommended loading techniques for plastic items.
It is advised to avoid placing plastic utensils or containers near the dishwasher’s heating element. The intense heat emitted by the heating element can cause the plastic to melt or warp.
Additionally, it is essential to properly space out plastic items to minimize contact with other surfaces during the wash and rinse cycles. This practice helps reduce the chances of plastic items entering direct contact with hot surfaces, safeguarding them from potential melting or deformation.
4. Avoid the Drying Cycle for Plastics
If your dishwasher offers the option, it is advisable to skip the drying cycle when washing plastic items.
The drying cycle typically generates high heat, which can harm plastic items, leading to melting or deformation. Instead, after the wash cycle is complete, open the dishwasher door and allow the plastic items to air dry naturally. This method avoids subjecting the plastic to excessive heat and minimizes the risk of melting.
By opting out of the drying cycle and choosing air drying instead, you can help preserve the integrity of your plastic items and ensure their longevity.
5. Use Dishwasher Settings Wisely
It’s crucial to utilize the dishwasher settings carefully to prevent plastic goods from melting, especially if your dishwasher has dedicated settings for plastics or sensitive items.
These specialized settings are designed to reduce water temperature and minimize extended exposure to high heat during the wash and rinse cycles.
Opting for these settings ensures that plastic items are subjected to milder conditions, reducing the risk of melting or deformation. Refer to your dishwasher’s user manual to identify if such settings are available and the recommended usage for plastic items.
Using these settings properly will help preserve the integrity of your plastic items while still achieving effective cleaning results.
6. Rack Adjustment
If your dishwasher features an adjustable upper rack, taking advantage of this functionality can help prevent plastic items from coming into direct contact with the heating element.
Consider lowering the upper rack to create more space between the plastic items and the heat source. This adjustment effectively increases the distance between the plastic and the intense heat generated by the heating element, reducing the risk of melting or warping.
By carefully positioning the plastic items in the dishwasher, ensuring they are adequately spaced and away from hot surfaces, you can significantly minimize the chances of plastic melting and maintain the quality of your dishwasher load.
7. Regular Maintenance
To ensure your dishwasher functions optimally and prevents plastic melting, it’s crucial to perform regular maintenance. This involves cleaning the filters and drains as recommended by the manufacturer.
Over time, residues from food, detergent, and other particles can accumulate in the filters and drains. If left unchecked, they can cause the dishwasher to overheat, which can melt plastic items in the dishwasher.
By cleaning the filters and drains regularly, you can effectively remove any potential residue sources and maintain proper water flow within the dishwasher. This simple maintenance task prevents plastic items from melting during the dishwasher cycle.
8. Repair or Replace a Damaged Heating Element
Suppose you observe any damage, discoloration, or melting on the dishwasher’s heating element.
