Far as I understand, the newest models lock the lid through the entire cycle, not just during spin. My 2004 IWL12 locks only during spin. My 1999 GWL08 with reed lid switch/magnet stops when the lid is opened during any operation that may involve basket rotation. During wash and rinse, it stops until such time as the auto water level sensing process is completed and agitation "officially" begins.
All EcoSmart models have the Eco Active shower/pretreat wash action, not just the Intuitive Eco model. GWL10 was the first U.S. model with that feature, followed by GWL11, IWL12, IWL15, GWL15, IWL16, up to the current WA37T26GW2.
