Many households trust Bosch dishwashers, and the reasons are not far-fetched, from impeccable reliability and outstanding cleaning performance. However, even high-end appliances require TLC to ensure pristine performance and longevity.
So, you don’t have to go bananas if your Bosch dishwasher is making clicking noises. It’s normal for this to happen and might signal that something is wrong with your appliance. Also, you don’t want to be too quick to chalk the noise problems as a red flag, as it might be your silver or dishes clanging in the machine.
Fret not! This post contains simple troubleshooting methods and easy DIY solutions to fix this problem.
Why does Your Bosch Dishwasher Make Click Noise?
While it’s normal for your Bosch dishwasher to make clicking sounds, sometimes it might be that some components are not functional. Your dishwasher makes a clicking noise because of the motor-driven electrical device as it goes through different washing cycles.
However, you should be more concerned if you notice other sounds coming from your device like thumping, swishing, snapping, banging, clunking, rattling, humming, or buzzing. Each sound points to a different problem, and it’s advisable to check the washer mid-way through the washing process to help get to the root of the problem.
Without further ado, let’s check out how to troubleshoot your washer depending on the type of sound it makes:
Normal sounds
As said earlier, your dishwasher will make some noises when operational. You might hear a clunk sound when you open the detergent cup. The swishing or sloshing noise might be from the spray arms delivering water.
Also, you might hear some humming sound when the washer drains water or when the soft food disposer is grounding food. Further, your Bosch dishwasher might be rattling or knocking noises when the dishes bump against each other or sprayed water hits the dishes or interior surfaces.
These noises are normal and do not signal opening up your dishwasher or calling a professional.
Maintenance Issues
If your dishwasher starts making a rattling noise like a grating, grinding, or crushing sound that extends to the next cycle, you might have a trapped debris problem at hand that demands immediate TLC. Once your dishwasher is done, allow it to cool before pulling out the lower rack and pumping the trapped bones, fruit pits, eggshells, and nuts.
For knocking noise coming from your dishwasher, might be because the drain hose is hitting the sides of where it’s housed. While this sound is not from damaged or faulty components in the dishwasher, it can be annoying and disturbing.
Also, a dishwasher with a lock feature might cause a clicking sound if it’s struggling to lock the door.
Repair Issues
Another reason your dishwasher is making a rattling noise or other noise can be due to worn out or damaged valves, motors, pumps, or other parts. But before you chalk up the noise to faulty components, it’s essential to check and determine whether the noise is not from hard food debris accumulated in the pump or dish bumping into one another or the wall of the dishwasher.
This appliance is not created equal. Hence, the difference in configuration and build quality results in different kinds of sound for the same reason.
What To Do If The Clicking Noise Is Heard?
Unlike other models, the latest dishwasher runs more quietly, but it isn’t uncanny for you to hear some noise as the machine cleans your dishes. However, the noise level can give you a real insight into how dire the situation is, why it’s likely occurring and how to solve it.
Once you hear the clicking sound, try to troubleshoot the noise and determine if the machine requires a quick DIY maintenance or repair issue by a qualified repair person.
How To Fix Bosch Dishwasher Clicking Noise – Quick Guide
Before seeking a professional, there are a couple of simple DIY solutions you can try if you are a bit handy.
Move the dishwasher
Your first act should be removing the dishwasher from the cabinet or wall. The noise might be due to the machine’s vibration bouncing off its surroundings. In some cases, the thumping or buzzing noise should stop.
If this is the issue, you should try to control the acoustics of the cabinets or walls before placing the dishwasher. The best way to do this is by adding acoustic pads and soundproof blankets to attenuate the noise level.
Clean the chopper blade
Clogged chopper blades are another major cause of grinding noise migrating from your washer. So, it would help if you started by dislodging any debris in the chopper blade. To gain access, you need to remove the lower spray arm. If the blades are already damaged, you should replace them.
Even better, you can avoid this problem in the future by rinsing your bowls and plate thoroughly before plonking them in the machine. Also, you should avoid putting your dishes with hard food items in the dishwasher.
Replace the pump
The motor and pump likely need a replacement when the machine makes a squealing or buzzing sound. How do you know which one of the components needs replacement? If the dishwasher isn’t cleaning your dishes effectively, it’s the wash pump at fault. But issues with pooled water, the drain pump is bad. However, your dishwasher won’t work with a faulty circulation pump.
Why is my new Bosch dishwasher so loud?
Although newer models run quieter, they still use a lot of water to clean and wash your dishes which causes some water noise. If you are wondering why your new Bosch dishwasher is making a loud noise, it’s likely the drain pump is forcing a lot of water down the drain.
Also, the loud noise might call your attention to the blocked water flow in the drain. Depending on the level of noise, it might be expected or a cause for you to contact you to inspect your machine.
Conclusion
While you don’t need to get overly worried about your Bosch dishwasher making clicking noises, you should be concerned if the noise level is high and unbearable. Usually, the problem is easy to diagnose using our simple troubleshooting methods and fix.
Nonetheless, you should consult a professional technician if the machine makes a clicking sound and is no longer working. Let them diagnose your device and suggest the best course of action – repair or replace the dishwasher.
