Although that has never stopped me before!
The yellow wire is 1/3 full
The Green wire is 2/3 full
The Red wire is full
As you can see, one good flush or two will turn on the 1/3 light.
the 2/3 light is about half full
The FULL light is about 7/8 full
NEVER dump below 2/3 and try to always dump with the full light on.
If below 2/3 light run the flush water until the full light comes on; then dump.
