Bosch is a long-running manufacturer of various household appliances, including washing machines, dishwashers, stoves, and of course refrigerators. Bosch is generally known for producing reliable products; but even with the most reliable technology, there’s always a chance for something to go wrong.

It’s not too common to experience issues with a Bosch refrigerator, but there are a few issues that can potentially happen. These include the fridge being unable to cool, the fridge making a loud noise, the fridge being unable to defrost, or problems with the fridge’s various dispensers.

Today, we’ll be taking a quick look at some of the issues you might encounter with your Bosch refrigerator, and explain why they happen and how you can deal with them.

Bosch Refrigerator Is Not Cooling

Let’s address the biggest issue first. Obviously, the point of a fridge is to keep your food cool, so if it’s not able to do that then you should make it a priority to get it fixed. Luckily, some of the more common issues that can cause your fridge to stop cooling can be easily corrected.

The first thing you should do if you notice your refrigerator isn’t cooling is to check the condenser coils. The condenser coils are usually located near the base or on the back of the refrigerator and are the part of the fridge’s cooling system that is responsible for dissipating heat from the coolant.

Over time, dust and debris get trapped in the condenser coils, which makes it a lot harder for the fridge to cool itself properly. If the problem gets back enough, the fridge might stop cooling entirely. Fortunately, you can solve this problem simply by cleaning the condenser coils.

Another common cause of a Bosch refrigerator being unable to cool is the failure of some of the cooling system’s fans. This could be the condenser fan, which moves air across the condenser coils, or the evaporator fan, which does the same for the evaporator coils. If the motors of either of these fans fail, you’ll have to replace them.

Other less common reasons why your refrigerator might not be cooling include the failure of the start relay, the temperature control thermostat, the start capacitor, the temperature control board, the compressor, the thermistor, or the main control board.

Bosch Refrigerator Is Making a Loud Noise

On the other hand, perhaps your fridge is working fine but is making a loud noise. It can be pretty annoying if your fridge is constantly whining or grinding while you’re trying to work in the kitchen. So, what’s the most common cause of such a noise?

Usually, the issue is with one of the fridge’s fans, since for the most part, the fans are the only things that actually move inside your fridge. There are two main fans to check out when trying to diagnose the source of your fridge’s noise, those being the evaporator fan and condenser fan.

If the problem is indeed one of your fans, the noise could be coming from either the blade or the motor. Try turning the blades by hand and see if they turn freely; if not, check to see if there’s something obstructing the blades or if there’s something rubbing against them.

It could also be that the motors for these fans are starting to wear down, as this can also cause a lot of noise. Unfortunately, if the motor is indeed the problem, you’ll have to replace the fan and its motor entirely.

There are other components of your fridge as well that can make a noise when they start to fail. It could be your fridge’s compressor, although fridge compressors, in general, are pretty reliable and can usually last for years without any problems.

If you notice your fridge is particularly noisy when the ice maker is filling, it could be the water inlet valve that is causing the problem. If the water inlet valve is the problem, you’ll have to replace it with a new one.

Bosch Refrigerator Water Dispenser Is Not Working

Not all Bosch refrigerators come with a water dispenser, but if yours does, this is another component that can potentially fail

The two most common reasons why your fridge’s water dispenser might stop working are a blockage in the water tube or a problem with the water inlet valve. It’s not terribly rare for ice to sometimes build up in the water tube, which will obviously prevent water from flowing through it.

To figure out if your water tube is blocked, disconnect the tube and try blowing through it. If you can’t get any air through it, there’s probably some ice trapped in there. Let the ice thaw out, and consider raising the temperature of your freezer a little bit to prevent this from happening in the future.

If you determine that your water inlet valve is the source of the issue, then you’ll have to have it replaced. The water dispenser may also fail to work if the water supply’s pressure is too low; ideally, the water pressure at the valve should be around 20 psi or so.

Other potential reasons for this issue include the failure of the dispenser control board, dispenser switch, or door switch (since the water dispenser won’t work if it thinks the door is open). It could also be a clogged water filter, so make sure you change your filters every 6 months or so. 

Bosch Refrigerator Ice Maker Is Not Working

The ice maker obviously isn’t an essential component of your fridge, but if your fridge is equipped with one then it’s certainly preferable to have it in working order. If your ice maker has stopped working, there could be a few reasons as to why.

The first reason could be that your freezer simply isn’t cold enough to produce ice efficiently. For the ice maker to work correctly, the temperature inside shouldn’t be higher than about 10 degrees Fahrenheit (-12 degrees Celsius). 

The problem could also be with the water inlet valve. If the valve fails, both your water dispenser and ice maker will stop working. Check the water valve, and replace it if necessary.

There could also be problems with the thermostat within the ice maker, the ice maker control board, or the ice maker assembly itself.

Ice Dispenser Is Not Working

First off, we think we should provide a little bit of clarification; the ice dispenser is NOT the same thing as the ice maker. The ice maker is what actually makes the ice, and the ice dispenser is what delivers that ice to you. If your fridge is able to make ice but can’t actually dispense it to you, the problem is likely with your ice dispenser.

It’s not very common at all for a fridge’s ice dispenser to fail, but there are a few reasons as to how this can happen. It could be a problem with the dispenser’s switch, or with the control board for the dispenser. It could also be one of the motors associated with the dispenser, the auger that pushes the ice down the chute, or the blade that crushes the ice.

If any one of these components has failed, the only real solution is to replace it.

Bosch Refrigerator Is Not Defrosting

Occasionally, you might have to defrost your freezer to prevent too much ice from building up inside it. This can make your freezer work less efficiently. Your Bosch fridge can run an automatic defrost cycle, but if certain components have failed then this might not work.

If your fridge’s defrost cycle isn’t working, you’ll want to check both the defrost control board and the defrost timer. If one or both of these things aren’t working, you’ll have to replace them before you can attempt another defrost cycle.

Other possible causes include a failed defrost thermostat, defrost heater assembly, or main control board.

FAQs

Let’s take a quick moment to answer some of the questions you might have about using your Bosch refrigerator.

What Temperature Should I Keep My Fridge/Freezer At?

Ideally, you should have your fridge temperature set between 37 and 39 degrees Fahrenheit, and your freezer temperature set between 0 and 10 degrees Celsius .

How Often Should I Replace My Fridge’s Water Filter?

If your fridge has a water dispenser, then it will also have a water filter. Over time, mineral deposits will build up over your water filter and make it a lot harder for water to pass through it.

Your fridge may give you an alert when it’s time to change the water filter, but if it doesn’t have that feature, you should change your fridge’s water filter about every 6 months. After installing the new filter, you should remove 5 minutes worth of water from the dispenser and one bin worth of ice cubes from your ice maker.

When Should I Defrost My Freezer?

If your freezer starts to accumulate a buildup of ice, you’ll need to defrost it. As we’ve mentioned, too much ice in your freezer lowers its efficiency by quite a bit.

You should defrost your freezer at least once a year, although if your freezer is prone to ice buildup then you should do this more frequently. In any case, you should also defrost your freezer if the layer of ice inside becomes more than ¼ of an inch thick.

What Kinds of Features Do Modern Fridges Have?

Fridges used to just be big boxes that kept your food cool, but these days they can do so much more than that. Modern fridges are equipped with a ton of features that add extra convenience and provide additional functionality to the fridge.

Water and ice dispensers are common features of fridges these days, but fridges also come with stuff like advanced temperature controls that allow you to, for example, change the temperature of a single crisper drawer while leaving the rest of the fridge the same temperature. Many fridges also come with adjustable shelving.

The most advanced fridges are “smart” fridges that come with WiFi connectivity. These smart fridges can keep track of your groceries and notify you when it’s time to get more, or they can immediately let you know if there’s an issue with the fridge that requires your attention.
