How to identify the signs of the failure

To identify the faulty seal is easy. The worn-our part will have the cracked surface and in some cases the ripped one. So the door will leak constantly and you’ll get puddles on the floor. In some cases the faulty seal will not let the door close completely, so the appliance will not start.

The seal is often out of order due to the following reasons:

  • stretching;
  • large cracks on the surface;
  • rips;
  • low-quility water and exposure to chemical detergents.

How to replace the door seal of the Siemens dishwasher

Before you begin the repair, we recommend you to unplug the appliance from the mains. You don’t need to disconnect the inlet and drain hoses. The old seal is almost impossible to repair. That’s why it needs to be replaced. You don’t need any additional replacement parts.

For the best quality repair of your dishwasher you need some tools. They are a knife, a small wide screwdriver for proper installation, and a hair dryer.

The steps are as follows:

  • Open the door;
  • Cut off the old seal using the knife. If you pre-heat the seal with the hairdryer at a minimum speed, the seal will be more flexible.
  • Clean the channel that holds the seal and then degrease the inner surface;
  • Install a new seal;
  • Close the door, plug the dishwasher to the mains outlet and run the appliance without dishes. Make sure it isn’t leaking.
