The EcoSmart name includes several model changes from GWL10 to the current. All are largely identical mechanically, but some differences in a few components and electrical design.

Although the machine spins during the "rinse" phase, the final spin is a separate function. It goes to full 1010 RPM only during the final spin period. The various spins during the Rinse phase are 25, 300, and 670 RPM.

Typically there are error/fault codes involved during malfunctions. Does the machine completely power off, or does it stop spinning with some lights flashing on the panel?

If your model is a GWL10, the electrical design has main power going through the pump. The pump has thermal overheat protection. If debris from the rug is clogging the pump, dragging on the impeller, it could overheat and shut off (coincidental at about 1/2 full spin speed), which makes the machine effectively dead until the thermal protector cools and resets.

Try running the pump for a few mins in Diagnostic Mode to see if it stays running or shuts off (which it should not). Or pull the pump to check/clear it of any debris. Do not remove the pump mounting bracket. Disconnect the wires. Find a plastic latch on the bracket, hold it released, rotate the entire pump counterclockwise, detach it from the bracket.

after my first post, i attempted to do a wash cycle again. i hit start and let it fill a bit and than toggled thru the panel till got to the rinse selection. seemed to pump water out and than it did the high speed final rinse. maybe it was a function of cooling down the unit like you say. so i have not attempted to wash a load of clothes yet. will keep you updated.
