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: Does a dishwasher drain hose need a loop?

• <div><p>To create a siphon break and remove any chance of dirty sink water or water that backs up into the sink from getting into your dishwasher, your dishwasher drain hose needs to have a high loop or an air gap device as part of its installation. All building codes require at least a high loop. In many places, it&rsquo;s necessary to install an air gap device to meet the code.</p></div>

Q: How do I maintain my dishwasher?

• <div><p>To extend the lifespan, clean filters regularly, run cleaning cycles with vinegar, avoid overloading, and check for leaks.</p></div>
