如果你需要拆開德國洗衣機的脫水桶，那么需要注意其中需要修理或更換的部分。 在拆解德國洗衣機的脫水桶時，需要注意以下幾點：

1. Safety first！ Always disconnect any electric or gas supply before attempting to do anything.

2. Open the access panel on the back of the washing machine.

3. Detach the drive belt from the motor and lift it off the transmission pulley.

4. Remove the water pump from the motor by depressing the locking tab and twisting the pump clockwise.

5. Remove the motor by first loosening the bolts that hold it to the chassis and then tilting it forward and out.

6. Unscrew the bolts that secure the transmission to the chassis.

7. The transmission will now be free to slide down and off the motor shaft. Be careful， as it is quite heavy.

8. The basket will be held in the outer tub by a large bolt or a retainer ring. Remove this and lift the basket out.

9. Now the inner tub will be exposed. It can be lifted out by pulling up on it as you rotate it.

10. Finally， the spider shaft that holds the inner tub in place will be visible. If this is damaged or corroded， it will need to be replaced.

By following these steps carefully， you should be able to disassemble your German washing machine's spin drum and repair or replace any necessary parts. Remember to always exercise caution when working around electrical or gas connections， and if you are not comfortable undertaking this repair on your own， seek the help of a qualified professional.
