Re: Bosch Excel 7 1200 spin noise loud then pop
I don’t know what is wrong with it, but try this to drain the water:
Disconnect from the electricity supply and turn off the water supply to the machine.
At the bottom front right there should be a small flap. Open this and there should be a narrow flexi hose with a cap on.
Get something for the water to drain into (there might be quite a bit) and open the cap on the flexi hose. The water should drain out, but might take a while. Have an old towel handy as there are always spills.
As to finding out what has caused it, while it is disconnected from the electricity and water you could take the back or top off and have a look inside. There are various videos on YouTube to show you how to do this.
