Dishwasher Installation questions, answered by experts

Yes, vinegar is an excellent homemade solution to clean a dishwasher. Its acidity will cut through any buildup, while its natural deodorizing capabilities will take care of any nasty smells.

It might be time to buy a new dishwasher for your kitchen if you consistently notice a significant amount of water left over after a cycle, indicating potential drainage issues that are becoming persistent or costly to fix. Visible rust, especially on the interior tub or racks, suggests internal corrosion that will likely worsen over time and can compromise cleaning performance. Additionally, if your dishes are coming out excessively hot after the drying cycle, it could point to a malfunctioning heating element or thermostat, which can be an energy inefficiency and a potential safety concern, making replacement a feasible choice.
