Rule of thumb...
Don't pay attention to the soap manufacture's suggested amount of use.
You must use use HE soap only.
If you can find Regular HE soap, use 2 tablespoons
2X HE Soap = 1 Tablespoon
3X HE Soap = 1 Teaspoons
Most digital-controlled front load washers have a software feature that consumers are unaware of.
If excess suds is detected by the MAIN BOARD (which monitors motor electrical load during rinse & final spin) the "suds kill mode" will be enabled.
This causes the washer DISPLAY CLOCK to stall.
The washer makes an attempt to reduce/remove suds--usually a futile attempt--and ends the cycle much longer than was originally shown on the DISPLAY.
