Q: Does a dishwasher need an air gap?

• <div><p>Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution. </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: Is it worth fixing a 20-year-old dishwasher?

• <div><p>It&rsquo;s not worth fixing a 20-year-old dishwasher or any 20-year-old appliance. Twenty years is beyond the useful life span of nearly every major household appliance. Once the appliance nears the end of its useful life span, repairs will become more frequent. A replacement often becomes more cost-effective at that point.</p></div>

Q: Do you need to drain a dishwasher before moving it?

• <div><p>If the dishwasher is in working condition, start and run a complete cycle with nothing inside. Let it drain and sit overnight before removing the hoses. In theory, it should effectively drain. You may find residual water in the hoses, but you can plug them. If the dishwasher breaks down midcycle it can sometimes be full of water. You&rsquo;ll need to manually remove the water with a plastic cup before removing the dishwasher. </p></div>

Q: How long does it take to repair a dishwasher?

• <div><p>Most repairs take 1-3 hours, but complex issues requiring part replacements may take longer if parts need to be ordered.</p></div>
