I hooked up my diswashing machine with contact microphones, a normal microphone and a stereo dictaphone within the machine with the dishes. Here is the results of the recordings. You can hear machiner, water running, and program changes.
The program is aorund 2 hours long, and here I have speeded up everything up som the whole program is finished within 8 minutes.
The dictaphone recoded 53 minutes, before crashing, probably due to the heat within.
