Plates and glasses can break in the dishwasher due to a combination of factors related to dishwasher design, dishwasher loading, and the fragility of the dishware. Here are some common reasons why this might happen:
Improper loading: If the plates or glasses are not loaded properly in the dishwasher, they can collide with each other during the wash cycle, leading to breakage. Avoid overcrowding the dishwasher and ensure that dishes are spaced out and placed securely in the racks.
Fragility of the dishware: Some plates and glasses are more delicate and prone to breakage than others. Fine china, crystal glassware, and certain types of ceramic dishes, for example, can be more susceptible to damage from the high-pressure water jets and mechanical movements in the dishwasher.
Temperature shock: Rapid temperature changes can cause glass and ceramic to expand or contract unevenly, leading to cracks or breakage. For instance, placing hot dishware directly under cold water during the rinse cycle can create thermal stress, increasing the risk of breakage.
Old or weakened dishware: Over time, dishware can develop small cracks or weaken, making them more prone to breaking in the dishwasher's harsh environment.
Impact with dishwasher components: During the wash cycle, dishware can come into contact with dishwasher components, such as spray arms or the dishwasher's interior walls, leading to breakage, especially if the dishwasher has a faulty or misaligned mechanism.
Dishwasher detergent and rinse aid: Certain dishwasher detergents and rinse aids may contain harsh chemicals that can damage the surface of plates and glasses over time, making them more susceptible to breakage.
Water pressure: If the water pressure in your dishwasher is too high, it can contribute to the force and impact on the dishware, potentially causing breakage.
To minimize the risk of breakage, consider the following tips:
- Load the dishwasher properly, ensuring enough space between dishes to avoid collisions.
- Use the appropriate dishwasher settings for delicate or fragile dishware.
- Inspect your dishware regularly for cracks or signs of weakness and replace any damaged items.
- Use dishwasher-safe and gentle detergents and rinse aids.
- Check the water pressure in your dishwasher and adjust if necessary.
Even with these precautions, some fragile dishware may still be better suited for handwashing to prolong their lifespan and reduce the risk of breakage.
