Q: What are common dishwasher problems?

• <div><p>Leaks, poor drainage, failure to start, water not heating, and excessive noise frequently require service.</p></div>

Q: What noise should a dishwasher make?

• <div><p>Not all dishwasher noises are signs of trouble, as dishwashers naturally make sounds during operation. Normal sounds for a functional dishwasher include humming, swishing, and sloshing. However, if you hear problematic noises such as pounding, drumming, grinding, or rattling, it could be a sign of an underlying issue, and you should consider having a technician inspect your appliance.</p></div>

Q: Why does my dishwasher keep filling with water at the bottom?

• <div><p>If your dishwasher keeps filling with water at the bottom but doesn&rsquo;t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it&rsquo;s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup. </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>
