• No effective feedback mechanism
• Large number of washes per week (approx. 200/site)
• Benign
Reasons for using Washing Machines

• Inline flow meters– Measure hot and cold
water flow• Datalogging system– Open Source Hardware:
Arduino Microcontroller– Software determines
cycle selected

• Performance anxiety• Different types of
laundry loads• Non-independence of
events• Other influences– Contamination from
other signs or other buildings
