Q: Is it necessary to descale a dishwasher?

• <div><p>Descaling a dishwasher is important if you want to keep it working as efficiently and effectively as possible. Limescale builds up quickly in dishwashers that are used regularly, especially in areas with hard tap water. You need to descale your dishwasher regularly to ensure that your dishes come out clean.</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: 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: Should flooring go under the dishwasher?

• <div><p>Yes, your kitchen flooring should extend under your dishwasher. It is essential for creating a level and stable surface for the appliance and preventing moisture from seeping into the subflooring, which is costly to repair. Working with a kitchen contractor will ensure the new flooring accounts for the height of the dishwasher so it sits under the countertop properly without any glaring gaps. </p></div>
