How to Clean Your Thermador Dishwasher: A Comprehensive Guide

When it comes to keeping your kitchen spotless, a dishwasher can be your best friend. Thermador dishwashers are known for their efficiency and reliability, but like any appliance, they require proper maintenance to function at their best. In this guide, we’ll walk you through the step-by-step process of cleaning your Thermador dishwasher to ensure sparkling clean dishes every time.

Gather Your Supplies

Before you begin cleaning your Thermador dishwasher, gather the following supplies:

  • Dish soap
  • White vinegar
  • Baking soda
  • Soft brush or toothbrush
  • Microfiber cloth
  • Soft, lint-free towel

Pre-Cleaning Preparation

  1. Safety First: Make sure the dishwasher is turned off and unplugged to avoid any accidents.
  2. Empty the Dishwasher: Remove all dishes, racks, and utensil holders before starting the cleaning process.
  3. Inspect for Debris: Check the bottom of the dishwasher for any food debris or foreign objects and remove them.

Cleaning the Interior

  1. Wipe Down the Interior: Dampen a microfiber cloth with a mixture of warm water and a few drops of dish soap. Gently wipe down the interior walls, door, and floor of the dishwasher.
  2. Focus on Crevices: Use a soft brush or toothbrush to clean hard-to-reach areas like the rubber gasket and corners.
  3. Clean the Racks: Remove the racks and clean them with warm soapy water. Check for any debris in the rollers and tracks.
  4. Tackle Mineral Buildup: Place a cup of white vinegar on the top rack and run a hot water cycle to help remove mineral buildup.

Cleaning the Exterior

  1. Wipe Down the Exterior: Use a damp cloth to wipe down the exterior of the dishwasher, including the control panel and buttons.
  2. Polish the Stainless Steel: For stainless steel exteriors, use a soft cloth and stainless steel cleaner to restore shine.

Caring for the Filters

  1. Locate the Filters: Most Thermador dishwashers have multiple filters at the bottom. Remove them for cleaning.
  2. Rinse the Filters: Rinse the filters under running water to remove food particles. Soak them in warm soapy water for deeper cleaning.
  3. Reassemble the Filters: Once dry, reassemble the filters and put them back in place.

Tackling the Spray Arms

  1. Remove the Spray Arms: Carefully detach the spray arms and rinse them under running water to dislodge any debris.
  2. Check for Clogs: Use a toothpick or fine wire to clear any clogs from the spray arm nozzles.

Dealing with Hard Water Stains

  1. Create a Paste: Mix baking soda with water to create a paste. Apply it to the stains and let it sit for a few minutes before gently scrubbing with a cloth.
  2. Vinegar Rinse: Run a cycle with a cup of white vinegar on the top rack to help remove hard water stains.

Maintaining the Gasket

  1. Inspect the Gasket: Regularly check the rubber gasket for mold or residue. Wipe it down with a cloth dampened with vinegar.
  2. Keep it Dry: After each use, leave the dishwasher door slightly ajar to allow the gasket to dry and prevent mold growth.

Cleaning the Control Panel

  1. Use a Soft Cloth: Wipe the control panel with a damp, soft cloth to remove fingerprints and stains. Avoid excessive moisture near the buttons.

Addressing Unpleasant Odors

  1. Check for Food Residue: Ensure no food scraps are trapped in the dishwasher. Clean the filter and spray arms to eliminate odors.
  2. Run an Empty Cycle: Occasionally run a cycle with baking soda sprinkled on the bottom to neutralize odors.

Monthly Maintenance Routine

Perform these steps monthly to keep your Thermador dishwasher in top shape:

  • Clean filters and spray arms
  • Run a hot water cycle with vinegar
  • Wipe down interior and exterior
