Keeping your Bosch dishwasher clean is crucial for optimal performance and hygiene. Regular cleaning gets rid of grease, food bits, and hard water stains. These can cause bad smells and lower efficiency.
Use this Bosch dishwasher cleaning guide for great results and a healthy appliance.
Why You Should Regularly Clean Your Bosch Dishwasher?

Regularly cleaning your Bosch dishwasher helps it run well. It also removes bad smells and extends its lifespan. Debris, grime, and mineral buildup can block filters, spray arms, and seals. This reduces wash quality.
- Food particles and grease accumulate in filters, causing odours and bacteria.
- Hard water leaves mineral deposits that reduce efficiency and block components.
- Routine cleaning prevents major repairs and keeps dishes spotless.
What You Need to Clean Your Bosch Dishwasher?
Before cleaning your dishwasher, gather a few essential tools. This ensures a thorough and efficient cleaning process.
- Soft cloth, sponge, and dish soap help wipe down interiors without scratching surfaces.
- White vinegar and baking soda naturally clean and deodorize.
- Toothbrush, pin, and dishwasher-safe bowl reach hard-to-clean areas and unclog spray holes.
Step 1: Clean the Bosch dishwasher filter.
The dishwasher filter traps food particles, preventing redepositing on dishes. Cleaning it regularly ensures proper drainage and cleanliness.
- Remove the bottom rack to access the filter; twist and lift it out.
- Rinse under warm water and scrub with a soft brush or a toothbrush.
- For greasy buildup, soak in a vinegar solution before reinstalling it securely.
Step 2: Clear and clean the spray arms.
Cleaning the spray arms of your Bosch dishwasher helps maintain strong water pressure. This ensures better coverage during wash cycles. Clogged holes reduce cleaning power.
- Detach the spray arms and rinse them under warm water to dislodge debris.
- Use a pin or toothpick to clear any blocked spray holes.
- If needed, soak in vinegar for 15–30 minutes to remove mineral buildup.
Step 3: Wipe down door seals and interior walls.
Food and grime collect around door seals, creating odours and mould risks. Cleaning these areas protects seals and ensures hygienic conditions.
- Wipe the seals and door edges with a soft cloth and soapy water.
- Focus on the bottom door edge, where moisture and debris often settle.
- Dry all surfaces with a clean microfiber towel to prevent mildew.
Step 4: Run a vinegar cycle for deep cleaning.
White vinegar is a natural cleaner. It cuts through grease and gets rid of odours in your dishwasher. This step also helps to clean internal pipes.
- Place a bowl filled with 2 cups of white vinegar on the top rack.
- Run a hot water cycle without detergent or dishes inside.
- The vinegar will break down residue and leave your dishwasher smelling fresh.
Step 5: Add baking soda for odour control.
After the vinegar cycle, baking soda helps remove stains and neutralize lingering odours. It also boosts shine on your dishwasher’s interior.
- Sprinkle 1 cup of baking soda evenly across the bottom of the dishwasher.
- Run a short, hot cycle with no dishes or detergent.
- This refreshes and deodorizes the interior, leaving it visibly cleaner.
Step 6: Use Bosch dishwasher cleaner or descaler.
For deep cleaning, use a Bosch dishwasher cleaner or descaler every few months. This helps remove hard water minerals and soap scum.
- Follow the instructions on the Bosch cleaner packaging for best results.
- Typically, place the cleaner in the basin and run a normal wash cycle.
- This step helps avoid performance issues in areas with hard water.
