Most units fill to just under the heating element.
Often with low water the pump will be noisy as it will suck in air during the wash.

To check if low water is your problem add a gallon or so of hot water to the unit after it fills and give it a try. Just be careful to not overfill it. The float should not float up as this is an overflow safety device.

If it now washes OK then odds are that the filter screen on the input side of the water valve is partially clogged. remove the valve from the machine and check/clean the screen. Do not permanently remove it from the screen as it is there to keep crud out of the valve which could hold it open and cause a flood.

Another common cause is debris in the sump. Remove the sump cover (center, inside of the tub) and check for debris or something wrapped around the chopper. Be careful as there is often broken glass in the sump.

Water valve is usually on the left hand side behind the kick plate.
The screen is built into the valve on it's input side.

Cannot say what is causing the white granules.
Could be calcium coming out of solution when the water is heated up.
The next time some show up put them in some vinegar if they dissolve it is probably calcium and you have hard water.

Do you drain some water out of you hot water tank on a regular basis.
My water is not hard and I still drain some out 3 times a year.
I let it run till it is nice and clear.
It always has some sediment in the bottom.

The vinegar is not dissolving the granules.

Also now I have a slight leak which appears to be coming from under the float. Is there any way to regulate the amount of water going into the machine? The tub looks quite full.

I will try turning the supply valve down a turn. It is not leaking a lot...just about a 1/2 ounce or so. It is draining well and there is no crud under the float cover. The float stem seems to be ok.
