Dishwasher water temperature may not be something most homeowners think about, but it’s one of the most important factors in how well your dishes get cleaned. If you’re in McDonough and trying to figure out why your dishwasher isn’t delivering sparkling results or if you’re shopping for a better model altogether, it might come down to the water temperature.
At A4L McDonough, we love helping busy families, first-time homeowners, and renters choose the right kitchen appliances. From dishwashers to refrigerators, washers, dryers, and ovens, getting the right appliance for your home isn’t just about features; it’s about knowing how to use them for the best performance.

Why Dishwasher Water Temperature Matters
For your dishwasher to do its job, the water needs to be hot enough to break down food particles, cut through grease, and sanitize your dishes. The optimal dishwasher water temperature is between 120°F and 150°F. Anything below 120°F won’t properly dissolve the detergent or eliminate bacteria. But water that’s too hot, above 150°F, can damage dishes, especially delicate glassware or plastic.
Many modern dishwashers now come with internal heaters, so they can boost the water temperature if your home’s water heater isn’t quite up to the task. That said, it’s still worth checking your settings. Simply run your kitchen tap for a few seconds and test the water temperature with a meat thermometer. If it’s not hitting at least 120°F, your dishwasher might not be cleaning as well as it could.

If you’re constantly re-washing dishes, it might be time to upgrade. At our McDonough showroom, we carry energy-efficient dishwashers with high-temp wash settings, smart cycles, and internal water heaters that make poor wash results a thing of the past.

Tips to Get the Best Results from Your Dishwasher
- Always run hot water in your sink before starting the dishwasher. This ensures hot water flows into the machine from the start.
- Use the “sanitize” cycle if your model includes one; it ensures a final rinse at the right dishwasher water temperature.
- Clean your dishwasher filter regularly to prevent food buildup and keep the wash cycle running efficiently.
- Don’t overload! Good water flow is critical, so give your dishes some space.
