Step-By-Step: How To Clean A KitchenAid Dishwasher

Empty the dishwasher and remove all racks to expose the tub and drain area.
Remove and inspect the filter. Use the dishwasher filter cleaning brush to dislodge debris and rinse under warm water.
Clean the spray arms using the dishwasher spray arm cleaning tool. Look for clogged holes and clear them with a gentle probe or the tool’s built-in pick.
Wipe the door gasket and tub corners with a soft cloth to remove grime and mold-prone buildup.
Run a cleaning cycle with descaling tablets for dishwasher following the manufacturer’s instructions. Use hot water for best descaling results.
If you notice persistent odors, run an extra cycle with a cup of white vinegar placed in a dishwasher-safe container on the upper rack (do not mix with detergents).
Inspect and clean the rinse aid area (if applicable) and refill as needed after cleaning cycles.
Reassemble racks and run a short cycle with an empty load to flush out any loosened debris.

Buying Guide

When selecting cleaning aids or maintenance gear for a KitchenAid dishwasher, consider size compatibility with standard dishwashers, ease of use, and compatibility with the model’s materials. Look for tools that reach tight corners, include flexible picks for spray arms, and feature soft bristles that won’t scratch surfaces.

Key factors to compare include:

<bSize and compatibility: Ensure tools fit inside your dishwasher’s interior and reach spray arms, filters, and gaskets.
<bNoise level and energy considerations of any cleaning appliance or cycle you use alongside cleaning products.
<bEnergy efficiency of cycles used for maintenance and descaling.
<bControls simplicity of any maintenance kit components that attach or operate with the dishwasher.
<bPlacement of products in the toolkit or cabinet for quick access during routine cleaning.

For practical comparison, consider how each tool aligns with your hard-water exposure, typical load sizes, and whether you prefer single-task brushes or a compact maintenance kit that covers spray arms, filters, and descaling. Do you typically run back-to-back cycles or need infrequent deep cleans? A balanced approach helps maintain reliability and cleanliness over time.
