Shannon-- Take heed of what Kevin posted above. It's possible the 2017 with the cycle dial isn't a true "set it anywhere I want to in the cycle" type of cycle control. I know this is true of the 2018 model with knobs. Can someone with a 2017 knobs/dial model confirm this before Shannon receives a washer she might not want? Please also confirm that the 2017 with knobs has a continuously variable water level control.
If your 2017 has both a regular 'set it anywhere within the cycle' control and a continuously variable water level control, you should be set! You might want to contact whomever you purchased from and ask those two questions to be sure.
Water Level on the electronic control model: It's easier just to select one of the four choices on the 9 Series machine. I've had to go up to the next higher level a few times, but the four choices are generally enough.
Here's the hack I sometimes use: Let's say it looks like the load should have a 'Medium' water level setting. When agitation begins, I might want a couple more gallons of water added. I hit the power button twice to power it down, hit it again to power it up, then increase the water level to 'Large' and let it fill to the desired level between medium and high. Hit the power button twice to power it down, then once to power it up, then choose either 'Medium' and the cycle will continue, but only fill to 'Medium' for the rinse. I usually opt for the lower setting for the rinse, since it only agitates for a couple of minutes.
Again, it's probably easier just to opt for the next higher water level from the start and walk away. But the hack is there if you want to use it.
