Common Bosch 11236VS Hammer Drill Problems

Keeping this in mind, we will be using this article to provide you with a list of common problems found on the Bosch 11236VS Hammer Drill, along with some troubleshooting steps.

  1. Hammering Feature Not Functioning

While the Bosch 11236VS Hammer Drill is an amazing device, running into problems with it is quite common.

This is why you must take proper care of your power tools when working on your projects.

One of the most common issues that people report is that the hammering function is not working properly.

The force created for the impact is made by using a piston that has to move freely inside a cylinder.

Considering this, if your hammer function is not working, then there is a high chance that the piston is at fault. You can start by taking apart the hammer drill and accessing its piston.

You will notice that this has small O-rings on it. These have to be replaced with new ones in case the old ones have scratches on them.

Simply doing this can help people in fixing most problems with the hammer function on their Bosch 11236VS Hammer Drill.

Although, if you notice that your device is still not working properly, then its hardware might have gotten damaged. This is quite rare, but the only option, in this case, is to get it replaced.

  1. Device Not Starting

Another common issue found with the Bosch power tool is that it stops working. You might notice that it is not starting up.

Alternatively, the tool might not be running properly. Whatever the case might be, one of the most common reasons for this can be that your power tool is not receiving enough power.

The Bosch 11236VS Hammer Drill is a powerful tool that requires a lot of electricity to function smoothly.

Without this, the motor will not spin properly, resulting in the drill not functioning.

Considering this, one thing that you can check is the condition of your power cable. If this is damaged, then replacing it with a new one should help in getting rid of the problem.

On the other hand, if the power cable is fine, then your motor might be running into issues.

You can check its performance by using a multimeter and then taking readings of the resistance on the motor. This will confirm if the motor is damaged or not.

  1. Lubrication Issues

Issues with the unit lubrication might not be that serious, but they sure can be annoying. Many users struggle to get this unit working after going through with the lubrication requirement.

Most of the time, these users are not lubricating the unit properly and using too much lubricant.

If you’re in the same boat and the unit won’t respond as well after lubricating, then you need to wipe away the excesses.


Similarly, you need to take a look at what type of lubricant you’re using. Going with cheaper options might sound great, but it will only hold you back in the long run.

So, switch to special gear lubricant and apply that will every brush change. Making this small change won’t have a huge impact on your budget, and you will be able to get the new option in no time.

So, be sure to make use of the new lubricant, and you’ll notice a better response from the unit.

All you’re trying to do here is make sure that you’re not using too much lubricant and that the type of lubricant matches the tool requirements.

Most of the time, that will be it when you’re dealing with minor connectivity errors with the system.

  1. Bearing Issues

Issues with the bearings are a bit more serious, and you will have to take the unit to the official Bosch repair center to get through these errors.


You’re bound to run into these issues after a few months of use. According to the experts, these bearings need to be replaced after 300 hours of use.

If you’ve been using this unit a bit too much in the past few months, then now is a good time to take it to the repair center.

It won’t be that heavy on your budget, and the control of the unit will improve a great deal.

All you’re trying to do is to adjust the noise problems from the system and ensure that the internal system doesn’t get damaged.

Holding off on this replacement will greatly decrease the lifespan of this device. 

So, be sure to keep that in mind and adjust the issues with the bearings when you keep running into these errors.

Hopefully, the system will start working perfectly from there, and you won’t have to visit the repair center for a few more weeks.

  1. Carbon Brush Issues

Lastly, the situation with the carbon brushes can also be annoying when you’re not keeping track of the unit maintenance.
