If your dishwasher has been sitting unused and dry for two years, there's a chance it may still work fine once you start using it again. However, there are a few things you should consider and check before running it to ensure it operates safely and efficiently:
Check for physical damage: Inspect the dishwasher for any visible signs of damage, such as cracks or leaks. Make sure all the components, including hoses and seals, appear intact.
Test the electrical components: Verify that the power cord and plug are in good condition. You can also check for any burnt or damaged wires.
Clean the interior: Even if it hasn't been used, dust and debris might have settled inside. Wipe down the interior and remove any dirt or cobwebs.
Inspect the water inlet and drain: Ensure that the water inlet valve is free of any blockages or mineral buildup. Also, check the drain hose and the drain pump to ensure they are clear and unobstructed.
Run a test cycle: Before loading any dishes, run the dishwasher through a test cycle to check for potential leaks. Keep an eye on it during the cycle to ensure everything is working correctly.
Monitor for leaks: After the test cycle, check around and beneath the dishwasher for any signs of leakage. If you notice any water pooling, immediately turn off the dishwasher and address the issue.
Start with a small load: Once you're satisfied that everything is in good condition, start using the dishwasher with a small load of dishes. Monitor it during the cycle to ensure there are no unexpected leaks or issues.
By following these steps and performing some basic maintenance, you can increase the chances of your dishwasher working fine after being idle for two years. However, it's essential to stay vigilant during the initial usage to avoid any potential water leaks or other problems. If you encounter any significant issues, it may be best to contact a professional technician to inspect and service the dishwasher.
