Q: Why is there water in the bottom of my dishwasher?

• <div><p>Water is sitting at the bottom of your dishwasher, likely because the filter is dirty with food debris or because the drain hose has a clog. If the water is still sticking around after following the steps above, it&rsquo;s time to contact a local plumber.</p></div>

Q: What is the most energy-efficient time to run the dishwasher?

• <div><p>Many people think this question relates directly to their electricity bill. Running your dishwasher at night both keeps your bill lower and is better for the environment. Energy rates tend to be much lower during off-peak hours. These hours are usually from 9 at night until around 6 in the morning. Your local utility provider will be able to tell you which hours are considered peak and off-peak. In conclusion, running your dishwasher during these off-peak hours is both better for your wallet and requires less energy from the grid, which is better for the environment.</p></div>

Q: Can you put bleach in a dishwasher to clean it?

• <div><p>Only if the dishwasher isn&rsquo;t made of stainless steel. The corrosive chemicals in bleach will stain stainless steel and can also cause further damage. To stay on the safe side, stick with an extra cycle of vinegar to banish any lingering odors.</p></div>

Q: How do you clean an old dishwasher without a filter?

• <div><p>To clean an old dishwasher without a filter, start by removing the bottom rack to access the drain area. Use a damp cloth or sponge to wipe down the interior, paying special attention to the corners and crevices where food particles and debris can build up. Pour a cup of white vinegar into a dishwasher-safe bowl and place it on the top rack, then run a hot water cycle to help break down grease and grime. After the cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short hot water cycle to deodorize and further clean the interior. </p></div>
