Are you dealing with a noisy Bosch dishwasher and hearing louder sounds than normal? If so, you’re not alone. Dealing with a loud dishwasher can be quite a puzzle, but it’s a common issue that many people face. Luckily, you’re in the right place to find a solution.
Noisy Bosch Dishwasher: Your Guide to Quieting Your Appliance
Having a noisy Bosch dishwasher can be a bit of a headache. To help you get rid of the problem we’ve put together a guide to help you answer “Why is my Bosch dishwasher making a loud noise?” and then we’ll show you the best ways to fix it.
The persistent beeping sound emanating from your dishwasher can be annoying. It’s usually a programmed alert to signify the end of a wash cycle. Fortunately, you can adjust or even disable this sound.
For many models, you can press and hold the cancel reset button along with the power button until the light turns on and the sound stops. Then, press the right cancel reset button multiple times to reduce the volume.
However, if this doesn’t work, you should consult your Bosch dishwasher’s owner’s manual. You can also find a digital copy via the Bosch Instruction Manual Search.
Rattling or Knocking Noises
A common cause of a noisy Bosch dishwasher is a rattling or knocking sound. This often indicates that the dishes have been loaded incorrectly, resulting in the spray arm hitting them.
To fix this, simply reorganize your dishes so that the spray arms can rotate fully without obstruction. Also, an overloaded or unevenly loaded dishwasher can lead to noise as dishes clash during the wash cycle. If this happens, pause the cycle, rearrange the dishes for a better fit, and distribute them evenly across the rack.
Utensils, plates, and bowls should be placed strategically to avoid contact with the spray arm. Pay attention to the positioning of larger items such as pans and cutting boards, ensuring that they are secured in a way that prevents them from moving and causing noise during the wash cycle.
Buzzing or Grinding Sounds
While a low-level buzzing sound is typical and signifies water being forced down the drain, a sudden grinding sound could indicate a problem. This could be due to a blocked or damaged pump impeller or filter, especially if your dishwasher isn’t draining well.
If you’re dealing with a Bosch dishwasher noise level that includes grinding, here’s how you can fix it:
- Remove the lower basket and spray arm.
- Take out the filter and check for any damage. Clean any dirt or residue.
- Use a sponge or towel to remove any standing water.
- With gloves on, carefully remove the pump cover (a teaspoon can help open the edge).
- Check the pump for any foreign objects or obstructions and remove them if possible.
- After ensuring the pump is clear, click the pump cover back on.
- Reinstall the filter, making sure the arrows align.
- Replace the spray arm and the basket, checking they move freely.
- Run a test wash to see if the dishwasher operates correctly.
If the pump or impeller appears damaged, or if there’s an obstruction you can’t remove, it’s time to call in professional help.
Regular Maintenance for Optimal Performance
Your Bosch dishwasher might be a cleaning superstar, but it also needs some cleaning itself! Over time, food particles, grease, and soap scum can build up, causing blockages, and unpleasant odors, and even affecting the appliance’s cleaning efficiency.
To keep it in optimal condition, aim to clean your Bosch dishwasher at least once a month. This should include cleaning the filter system, the spray arms, and the interior walls and door. Specialized dishwasher cleaning products can be used to remove stubborn grease and limescale build-up.
