How to Remove a Stuck Screw from a Bosch Washing Machine Soap Box

Hi, thanks for your question.

Replacing the door seal on a Bosch washing machine can be challenging, particularly if you're tackling it for the first time without removing the front panel. The real obstacle is usually a single steel screw located in the soap drawer—and it's often the most stubborn part of the job.

The reason this screw causes so much trouble is material incompatibility. Whilst the majority of fasteners on your machine are aluminium, this particular screw is steel. Over time, the different metals can corrode together, creating a bond that's extremely difficult to break. I've encountered this problem countless times during repairs, and drilling it out is often the most practical solution.

The drilling method

To remove the screw safely, you'll need a drill bit that's slightly larger than the screw's shaft diameter. The goal is to drill through the head and separate it from the shaft, allowing you to extract the broken pieces. The key is working carefully around the plastic housing—one slip can crack the soap drawer casing, which creates additional expense and hassle.

Once the head is drilled away, you can access the remaining shaft from inside the machine and remove it using bolt cutters or a similar tool. This two-stage approach minimises damage to surrounding components.

I've included a video demonstration below showing the exact technique I use for this repair. The footage starts at the point where the drilling begins, so you can see the angle, speed, and pressure needed to do this safely.

Tools and equipment

you will find the pliers very helpful for moving the bands and replacing the bands that hold the dual seal in place 

Beyond a standard drill and appropriately sized bit, having the right tools on hand makes this job considerably easier. I've linked to several items I regularly recommend for this specific repair, including bolt cutters for removing the shaft remnant and a multimeter for diagnosing electrical issues or measuring power consumption during a wash cycle. A multimeter is particularly useful if you're investigating why a machine is behaving unexpectedly or want to understand its energy usage patterns.

Hi Paul,
Thank you so much for your reply and video link. I had already decided I needed to drill out the seized screw, and I ended up cutting off the tip of the screw inside the machine with a blunt hacksaw (no bolt cutters unfortunately). I eventually succeeded in replacing the seal although the springs were very tricky, you need very strong hands! So the machine is now working perfectly again. You also helped me replace an oven element a while backso I'll buy you a pint!
All the best, Brigid Sealy in Ireland
