Bosch Microwave Not Working (How to Fix/Reset)

Bosch make a range of quality home appliances. Appliances will tend to work for long periods of time without any issues but from time to time they can have various problems. Today, I will cover what to do if your Bosch microwave is not working.

In general, ensure the door is closed completely, and the child lock is off. After that, do a reset of your Bosch microwave by disconnecting it from the power and then reconnecting it again after 10 seconds. If it’s still not working, have a qualified technician repair it for you.

To turn the child lock off, hold down the START button for 4 seconds. But, Bosch microwaves without an LCD display don’t have a child lock. Below, I will describe more specific issues with Bosch microwaves such as the LCD display not working, and the turntable not spinning.

Bosch Microwave Not Working (How to Fix/Reset)

You shouldn’t attempt to repair any of the internal wiring on a Bosch microwave as they have adapters that send large amounts of power through them. But, there are a range of simple fixes that don’t involve opening the internal workings of your microwave. This is what you should do if your Bosch microwave isn’t working.

As a general rule, make sure you’ve selected the time, and turned the dial or pressed start to start your Bosch microwave. Otherwise, your Bosch microwave may need to be restarted, the wall outlet isn’t providing any electricity, or the door isn’t closed all the way.

The first thing to start with is checking the door is closed properly. Open, and close the door ensuring it gives a click. Press a bit firmly on the door to make sure.

If it still doesn’t start when you turn the dial, or press the start button then reset your Bosch microwave. Simply, disconnect it from the power for 10 seconds, and then connect to the power again.

This can be done by turning it off at the wall outlet, or unplugging it from the wall outlet. If you don’t have easy access you can switch it off at the circuit breaker. Wait 10 seconds, and then turn the circuit breaker back on.

Bosch Microwave Not Heating

Using the microwave in the kitchen

After about a minute or two foods and drinks will be noticeably hotter. If they’re not it’s a clear sign that your Bosch microwave is not heating properly. This is what to do if your Bosch microwave is not heating.

Generally, the heat setting can be set to low and you need to set it to a higher setting, you are heating a large amount of food or drink, this requires more cook time. Or, the food is particularly cold, which requires more time for the food to heat up.

A good rule of thumb is to test whether it’s heating by heating up a glass of cold water. After 1 to 2 minutes it should be very hot. This will show you if it’s heating at all.

When it’s completely cold it indicates there’s an issue with one of the internal components. Fixing this is best done by a qualified technician. Contact Bosch support to see if your microwave is under warranty, and they can also let you know the best way to get a repair technician to repair it for you.

Bosch Microwave Not Spinning

Using the microwave in the kitchen

When your Bosch microwave is operating properly the plate will spin to allow the food to cook evenly. A microwave can still heat food effectively if the turntable is not spinning, but it’s better if it does. If the turntable on your microwave isn’t spinning, here’s how to fix it.

In general, it’s because the turntable or roller ring is not fitted correctly, or the turntable has been disabled in the settings. Adjust the turntable and roller ring so that they’re lined up with the spinning mechanism, and the groove where the roller ring sits.

On many Bosch microwaves there is a button that says ‘Turntable on/off’. When you press it it will toggle the turntable and off. Press it once to turn it back on. It’s very common for the spinning plate to come off the spinning mechanism, or to not place it correctly back on to the spinning mechanism after you clean it.

If it’s not spinning when it’s fitted correctly then the spinning mechanism is faulty. It will need to be repaired, or the component underneath it will need to be repaired or replaced. In that case, you should contact Bosch to have a qualified technician do the repair for you.

Bosch Microwave Not Starting

Using the microwave in the kitchen

Bosch microwaves are of two types, they can have a digital LCD display, or have a turn dial, with buttons. In either case, when you set the time and press START it will start cooking right away. If it’s not starting, here’s what you should do.

Overall, the child proof lock can be on, and needs to be disabled. To disable the child lock press the STOP button once to clear anything on the screen, then hold the start button for 4 seconds. Otherwise, there is a fault with your microwave that needs to be repaired by a registered technician.

It’s not possible to set a child lock for a Bosch microwave that doesn’t have an LCD display. Therefore, skip trying to disable the child lock if your microwave is the type that has a turn dial.

  • If you’re tried disabling the child lock:
    Check the door is closed completely with a reassuring click
  • Do a reset of your Bosch microwave

To reset your Bosch microwave, disconnect it from the power by unplugging it at the wall outlet, or turning off the circuit breaker at your switchboard. Wait for 10 seconds and then reconnect it to the power by plugging it back in, or turning the circuit breaker back on.

Bosch Microwave Not Closing

Using the microwave in the kitchen

The door of a Bosch microwave needs to be closed completely for it to start. It will typically give a reassuring click to let you know that it’s fully closed. If the door on your Bosch microwave isn’t closing properly then here’s what causes this to happen, and how to fix this issue.

As a general rule, this is because the door latch is faulty, and it needs to be replaced. Microwaves have large amounts of electricity running through them. Therefore, you should have a qualified technician fix the latch for you.

Before doing that it’s a good idea to inspect the door, and the area around the door. There could be some food remnants or something else lodged in the door hinge that is preventing it from closing.

The door latch might also be a little bit out of place. And adjusting it slightly can click it back into the correct position.

Bosch Microwave Not Showing Time

Using the microwave in the kitchen

Having your Bosch microwave display the time is helpful when you’re in your kitchen. It can have the incorrect time, or not show the time at all. To get your microwave to display the time, here’s what to do.

Generally, the setting to make the time show needs to be turned on. It’s not turned on by default. To enable the clock, tap the ‘clock’ button on the control panel, then input the time using the number pad, then tap ‘clock’ again to save it.

Most Bosch microwaves can only show the time in 12 hour mode not a 24 hour clock. When the power to your microwave gets disconnected, it will reset your Bosch microwave, which will wipe the clock.

Bosch Microwave Light Not Working

Using the microwave in the kitchen

The light is very helpful on a microwave so you can see if your food or drink is getting close to boiling over, or has boiled over already. The light is controlled by bulbs in the interior of your microwave. The bulb can blow, or be not working for another reason, here’s what causes this to happen and how to get your Bosch microwave light working again.

In general, the light bulb has blown. A replacement bulb needs to be installed. To do that first unplug your Bosch microwave, then unscrew the light bulb cover. After that unscrew the existing light bulb, and screw in the new one.

You can order replacement bulbs from many microwave parts websites online. Many are very good and allow you to put in your model number.

It will then bring up the relevant bulb. Refer to this page on the official Bosch website which shows where the serial number is located for all of the different types of Bosch microwaves.

Bosch Microwave Buttons Not Working

The buttons on your Bosch microwave need to work to operate it. They can not be working for a range of reasons. Here’s how to troubleshoot the buttons not working on your Bosch microwave.

Generally, first restarting your Bosch microwave. Do that by unplugging it at the wall outlet. Then wait 10 seconds, and plug the power cord back into the wall outlet. The child lock can also be on, to deactivate it press STOP/CLEAR once, then hold the START button for 4 seconds.

The door can also not be closed completely. Open the door, and close it again making sure it’s fully closed. The LCD display can also be wet, or slightly dirty.

Give it a wipe using a damp cloth, and then dry it thoroughly with a paper towel or dish towel. If the buttons still aren’t working there can be an internal fault with one of the components. Get in touch with Bosch support to organize a repair technician, and to see if it’s covered under warranty.

Bosch Microwave Dial Not Working

Using the microwave in the kitchen

There are two types of dials on Bosch microwaves, there is the analog dial used to select the time, and there is the digital dial ring. Both can have an issue and stop working. To fix this issue, here’s a summary of what to do.

In general, this is because the dial is faulty or is slightly loose. Begin, by restarting your Bosch microwave, by disconnecting from the power for 10 seconds, and then connecting it to the power again. The fingers or the dial can also be slightly wet, make sure it’s completely dry and clean.

If neither of these steps fixed it then the dial needs to be repaired. Microwaves have a very high amount of electricity running through them.

Therefore, this repair is best done by a registered technician. Contact Bosch support to organize one to repair it for you.

Bosch Microwave Display Not Working

Using the microwave in the kitchen

The display will always be lit up, and the buttons can be used to use your Bosch microwave. If the display is completely blank, or doesn’t show anything when you press the different buttons to operate it, here’s a rundown of how to get it working again.

As a general rule, the child lock is enabled, and you need to disable it. Hold down the START button for 4 seconds to turn off the child lock. The wall outlet may also not be providing any electricity. Test it by plugging something else into the same wall outlet. Additional steps are explained below.

It’s also possible the display is faulty due, and it needs to be repaired by a qualified technician. You should test the wall outlet by plugging another device into it. A phone charger isn’t normally on hand and easy to test.

If the wall outlet isn’t supplying any power inspect the circuit breakers on your switchboard. The circuit breaker can have clicked into the off position due to a power surge. Or, if the area of your house where your microwave is, draws too much power.

Clicking back into the on position will return power to the wall outlet. If it is getting power do a reset of your Bosch microwave. This is done by unplugging it from the wall outlet, waiting for about 10 seconds, and then plugging it back in. If the digital display still doesn’t light up, then contact Bosch support to organize a qualified technician to repair it for you.

Bosch Microwave Keeps Beeping

After a cook cycle your Bosch microwave will beep to let you know it’s finished. A fault can occur with microwaves where they don’t stop beeping. Here’s instructions for what to do if your Bosch microwave won’t stop beeping.

In general, first open and close the door. Then press any key. If it continues to beep then restart your Bosch microwave by unplugging it at the wall outlet for 10 seconds, then plug it in again. If that hasn’t stopped the issue, get in touch with Bosch support.

When you need to press any key after you open and close the door it indicates there’s an issue with your Bosch microwave, it will typically display an error code on the LCD display. This needs to be repaired by a qualified technician. In the meantime it’s a good idea to disconnect it from the power to stop it from beeping, while you have it repaired.

Bosch Microwave Keeps Running

The internal computer on your Bosch microwave controls the different functionality. After a cook cycle has finished your Bosch microwave will automatically stop cooking, and it will beep to let you know it’s done. There can be an issue with your microwave where it will continue to run, this is what causes it and what to do when you have this issue.

Typically, there is a fault with the internal computer on your Bosch microwave, restart your microwave. This is done by unplugging it while it’s turned on. Then wait for 10 seconds and then plug it back in. If the problem persists it can only be fixed by a registered technician.

It can be covered by your warranty. Therefore, you should contact Bosch support. They can advise you how to get a registered technician to repair it for you, if it’s covered by warranty, and how to have it repaired under warranty.

Bosch Microwave Keeps Shutting Off

Using the microwave in the kitchen

A somewhat annoying issue can occur with microwaves and other electronic appliances where they seem to be working fine but then suddenly stop working. This generally indicates an issue with the electricity supply to your microwave. When this happens with your Bosch microwave, here’s what to do.

In general, there is an internal fault. This can only be fixed by a qualified technician. It’s possible your wall outlet is overloaded, particularly if you have more than one appliance plugged into it. Remove any other devices plugged into the same wall outlet, and see if the problem recurs.

The best way to test if it’s an issue with the wall outlet, or with your microwave is to take your microwave to a completely different part of the house and see if the problem still happens. It can be an issue with the internal wiring in your home, and requires an electrician to repair it. Old wiring or faulty wiring will cut in and out, and won’t supply consistent electricity.

Which can cause your microwave to shut off when it tries to draw enough power to operate. But, before doing that it’s best to see if it’s isolated to your microwave. If you have more than a few appliances plugged into the same wall outlet, or in wall outlets nearby, for example, if you’re using a multiport adapter, it can demand too much power from one circuit breaker.

As a result, it won’t be able to draw enough power, and your microwave will shut off. Identify if you do have a setup like this, and consider using a different port for other appliances to spread the load.

Bosch Microwave Keeps Blowing Fuse

Using the microwave in the kitchen

Circuit breakers will rarely click into the off position unless there is an issue with the wiring in your home, or with the way you have your appliances set up. When this happens, frequently such as every time you use your Bosch microwave, here’s instructions for how to fix this problem.

As a general rule, this indicates you have faulty wiring in your home and you should have a registered electrician inspect the wiring for your home. The wall outlet, or nearby wall outlets can also have too many things plugged into them. This can draw too much power and blow a fuse.

A good first check is to plug your microwave into a completely different part of the house. This will help you isolate whether it’s the specific wall outlet, or another issue. Also, if you have more than 3 appliances/devices plugged into the same wall outlet, plug some of them into other outlets to spread the load on a particular part of the house.

Then see if the issue recurs. If it still happens your microwave can be faulty and be drawing too much power. Or, the wiring in your home can be faulty and needs to be repaired.

It’s impossible to know which it is. Therefore, you’ll need to decide which one you want to get repaired first.

Bosch Microwave Keeps Stopping

Using the microwave in the kitchen

In a normal cook cycle on a Bosch microwave it will complete the entire cook time and then stop. There can be a fault with a Bosch microwave where it will stop part way through a cook cycle, or shut off completely. Here’s what causes this to happen and what you should do to troubleshoot this problem.

As a general rule, there is an issue with one of the internal components, and it needs to be repaired by a qualified technician. But, it’s worth trying restarting your microwave, and unplugging other devices plugged into nearby outlets. It may also be on a defrost cycle.

A defrost cycle will stop part way through the total cook time. Defrosting food requires you turn the food over a few times. It will stop part way through for you to turn the food over.

It’s possible your microwave isn’t able to draw enough power, which causes it to shut off. To restart your Bosch microwave unplug it from the wall outlet for 10 seconds, then plug it in again.

After trying each of these, contact Bosch support to organize a repair technician to repair it. They can also explain if the repair is covered under warranty.

How to Reset Bosch Microwave

Using the microwave in the kitchen

There are numerous faults that can occur with a Bosch microwave, and resetting it is a good first step to fix these. Here’s how to reset your Bosch microwave.

In general, disconnect the power to your Bosch microwave, wait 10 seconds, and then reconnect it again. You can unplug it at the wall outlet, or turn off the circuit breaker at the switchboard.

Some kitchen configurations make it difficult to access the wall outlet, so switching it off at the circuit breaker is a better idea. However, the downside is that you will typically need to reprogram nearby appliances that also get turned off when you do that. Therefore, ideally, unplug it at the wall rather than turning it off the circuit breaker at the switchboard.
