The task of cleaning the dishwasher is not something we remember. Until an unpleasant odour reminds us that it’s past due, then cleaning it is a difficult task. What can you do about dishwasher odour? To eliminate bad smells, our Bosch dishwasher cleaning tips will show you how to clean the dishwasher from the tub to its spray arms.

Bosch Dishwasher Cleaning 101: Preventing and Eliminating Odours

Bosch dishwasher cleaning tips are effective in eliminating odours at the source using basic household cleaning tools and proper cleaning techniques. We will also talk about how proper maintenance can help prevent odours. Clean the dishwasher filter
The dishwasher filter filters out food particles that could clog the drain. These food particles can build up over time and cause an unpleasant odour.

This is how to clean a Bosch dishwasher to get rid of odorous food particles.

  • Take out the spray arm and lower rack of your dishwasher.
  • To remove the mesh screen and filter, twist the cap.
  • Warm water is sufficient to rinse the filter and screen.
  • Put the filter back into the dishwasher. To lock the filter in place, twist the cap in the opposite direction.
  • Replace the spray arm and lower rack.

Dishwasher Tub Cleaning

The dishwasher tub can be a moist, warm environment which can easily grow bacteria from leftover food particles. This is how to clean your Bosch dishwasher tub.

  • White vinegar: Place 1 cup of white vinegar into an empty dishwasher base and run a heavy cleaning cycle.
  • Baking soda: After running the vinegar cycle, add 1 cup of baking soda to the dishwasher’s base. Let it sit overnight. In the morning, run a regular, empty cycle.
  • Bleach: To prevent persistent mildew buildup, add 1 cup of bleach to the dishwasher’s base and run the third cycle. If your dishwasher’s interior is stainless steel, skip this step as bleach can cause discolouration.

Arms of the Dishwasher Spray Arms

Food particles can block the spray arms of a dishwasher, making it difficult for water to spray outward. This causes dishes to get dirty. Although proper dishwasher loading techniques can help prevent this, mould and mildew can build up on the spray arms and cause persistent odour. These are the steps for cleaning your Bosch dishwasher spray arms.

  • Take out the lower racks of your dishwasher.
  • To remove the spray arm, lift it up and twist the knob on the upper arm.
  • To remove food particles and other debris from the holes in each arm, use a toothpick.
  • Warm water is sufficient to rinse each arm.
  • Use a clean cloth to dry.
  • Attach the spray arms.
  • Clean and inspect the drain line

If the Bosch dishwasher’s smell persists after following these steps, it could be due to a blocked drain line.

This is how to check the drain line and remove the clog.

  • Use a screwdriver or pliers to disconnect the drain hose and the air cap from the garbage disposal.
  • You can check for blockages using a dishwasher cleaning cycle. A blockage is when the hose does not drain.
  • To remove the clog, use a straightened hanger/plumber snake.
  • If the hose does not drain, the problem is most likely in the drain line behind the dishwasher. This is a more complicated repair so we recommend hiring a professional to clear the clog.

Tips to Prevent Dishwasher Odours

Regular maintenance can include our Bosch dishwasher cleaning tips to keep odours from returning. These tips can be used proactively to prevent odours:

The dishwasher filter should be cleaned on a monthly basis.
Every month, clean the dishwasher tub and wipe it down with a damp cloth after each use.

Bosch recommends that you use FINISH detergent to get the best odour reduction results. Do not use too much detergent as soap residue can cause smelly bacteria. Use the minimum amount of detergent as recommended on the package.

If your Bosch dishwasher cleaning leaves behind a persistent odour, it might be time to call a dishwasher repair company.
