Are the clothes clean with the existing water level?

Hvtech, good answer even through it has nothing to do with the question. I too would like to know if this would work without hearing that I may be the cause of the planets problems. I regularly have to hold the water level selector to "reset" just to get a full tub. I'm tired of not being able to get a full load and even more annoyed but not being able to get a real hot fill. I'm just sayin...

Even though I have to roll my eyes at all that "there' ain't no wadrrr in my washrrr - dat thang don't clean my clothes" talk...

... yes, it should work. I looked up a thread where someone did just that - more or less.

I apologize for not answering your question but when people ask how to raise water level without giving any sort of performance complaint or reason for doing so I have to wonder why. It seems that there are many people who have psychological issues with low water levels in washers.

BTW I am not against raising water levels because of environmental impact, but if people are getting poor results with their HE washers there may be things that can be done about that while still operating the machine within the manufacturer's specifications to ensure longevity and intact warranties.

thanks, hvtech, I had no idea it would take such a large volume of air to make a difference in the water level. I'll advise my dad of this and see if he is interested in adding a container to the pressure sensing tubing.

FWIW, I went through a brief phase of experimentation with our FL, where I manually added more water to the wash cycle, the low-tech way --- I paused the machine and poured water into the drum until it reached the bottom of the door.

The only thing this accomplished was creating more suds, which were a pain to get out of the wash (extra extra extra rinses). Suds do not go away easily. Clothes did not come out cleaner.

My low-tech scientific conclusion was to let the machine do its own thing.
