Today I thought I encountered a bug for the time delay feature on my washing machine. I never used it until today.

Steps to reproduce

  1. Put dirty laundry in the washing machine
  2. Press On/Off button to turn it on
  3. Press Time Delay until I see ‘1 hr’ on the display
  4. Start the program
  5. At this point, I realized I still had clothes to load in to the washing machine
  6. Press On/Off button to turn it off
  7. Load the rest of the clothes in
  8. Press On/Off button to turn it on again

Expected Results

I turned off the washing machine on step 6, so I expect the state of the time delay to be cleared. This is an inconsistency with comparable products. I am comparing this washing machine to a calculator or a computer.

Actual Results

The washing machine remembers the ‘1 hr’ time delay option.

Note: I later realized I simply needed to press Time Delay another 11 times to cycle back to OFF. The time delay options include ‘OFF’, ‘1 hr’, ‘2hr’ up until ‘12 hrs’.

Conclusion

It may be a bug to me, but not a bug according to how it was designed. How could this have been spotted earlier? UAT perhaps?

Maybe I should go and do follow up testing on other washing machines.
