Where Did Large Go?

My background in technical writing has apparently made me highly sensitive to how devices and control mechanisms are labeled. I always get a little perturbed when technology doesn’t make sense. Here’s the latest example:

What happened to the ‘Large’ setting? Did the user interface designer go to the Starbucks school of sizing? Hmm…I suppose if they had, the sizes would just be Medium, Large and Extra Large.

This is a classic ‘level of abstraction’ problem. I assume that the washer uses this setting to determine the water level in the tank. Why not just show the water levels and trust humans to correlate their pile of laundry to the level of water in the tank?
