ToggleWhy You Should Clean Your Bosch Dishwasher
Maintaining the cleanliness of your dishwasher is crucial when it comes to its performance. Not only will it improve its efficiency but it will also extends its lifespan.

For example, food particles, grease, undissolved detergent, and water minerals can build up inside over time. This buildup may cause spots and film on glassware, dinnerware, and flatware, if left unattended.
Bosch recommends that you clean your dishwasher once every few months for optimal performance.
Familiarizing Yourself With The Different Components
Your Bosch dishwasher is a complex machine, made up of several crucial parts that need regular cleaning to perform optimally. Here’s what you need to know.
Cleaning the Dishwasher Filter

The dishwasher filter is responsible for catching food particles during the wash cycle, preventing them from re-entering your dishes or clogging the drain pump.
Given that, it’s crucial that you clean it regularly. You can use warm water and mild soap, or if necessary, you can gently scrub using a soft brush, then rinse under running water before reinstalling.
Caring For the Spray Arms and Stainless Steel Surfaces
The spray arms are responsible for evenly distributing water throughout the dish racks during cycles. Over time, however, food debris can get caught in the small holes.
If you find any obstruction – don’t panic. Remove it carefully under lukewarm water until they’re sparkling again because having clean spray arms means an effective dishwasher wash every time.
The stainless steel interior needs to be cleaned regularly too and that involves wiping the surfaces with lukewarm water.
Descaling Your Bosch Dishwasher
For stubborn stains or hard water deposits, Bosch Descaler can help break down mineral buildup and keep your dishwasher clean.
White vinegar and citric acid can help dissolve hard water deposits, but Bosch recommends avoiding them in its dishwashers since they may damage certain components.
Running a Bosch Machine Care Cycle
The Bosch Machine Care cycle is designed to clean the inside of your dishwasher by removing grease, detergent residue, and buildup. Depending on the model, the cycle can take anywhere from 60 to 120 minutes.
To use it, make sure the dishwasher is empty and add an ACTIVE tablet to the detergent dispenser tray. Next, select and run a Machine Care cycle.
How to Start the Bosch Machine Care Cycle by Series
The button sequence may vary depending on your dishwasher’s model. If your model isn’t listed, refer to the instruction manual.
| Bosch Series | Cycle Name | How to Start |
| 300 Series | Machine Care | Select “Machine Care”, then press “Start” |
| 500 Series | Machine Care | Select “Machine Care”, then press “Start” |
| 800 Series | Machine Care | Select “Machine Care”, then press “Start” or use the Home Connect mobile app |
| Ascenta Series | N/A | N/A |
| Benchmark Series | Machine Care | Use the Home Connect mobile app |

Troubleshooting Common Issues with Bosch Dishwashers
When your Bosch dishwasher starts acting up, it can be frustrating. But don’t fret. We’ve got your back – assisting you in diagnosing and solving those pesky problems with your Bosch dishwasher.
Clean Your Dishwasher Filter and Spray Arm

If your dishes aren’t coming out as clean as they used to, food particles might be blocking the spray arms or dishwasher filter.
Start by removing everything so you have an empty dishwasher. Soak the spray arms and filter for about 15 minutes with warm soapy water, then add some baking soda to gently scrub off any debris caught in the nozzles of the spray arms.
Don’t forget to rinse them under running water before fitting back into place.
Drain Pump Problems
The drain pump is another component that can cause issues if it’s not maintained properly.
For example, you may need to hire a repair technician if you notice unusual sounds during wash cycles or find excess water at the end of each cycle.
