How far uphill can a washing machine pump water?

Pull it out enough to take off the back cover and watch it while it runs. You'll
probably find a cracked hose or some such.

That's true, it should not "piddle". If it is trying to pump
against too high
a head, it should just sit there and grunt.
Washer discharge pumps are not designed to deliver any significant
head
are are very low pressure pumps. Remember, it takes about .44 psi to
lift the water 1 foot, so 80 inches or 6 1/2 feet is only about a 3
psi requirement.
Anyway, the instruction manual with your washer might tell you
lthe
max head it will service. If not, the discharge hose supplied with
the unit
is a good idea of something near the max.....
However, it should not "piddle" under any condition unless it leaks
out
the end of the hose.... If you assembled the hose to the unit
yourself,
keep an eye on the connection to the pump while the unit is running.
If the hose is intact, you may need a better clamp...

Checked hose, all connections dry, and no obvious kinks. However, there
is a ribbed/hoseclamped coupler where the factory hose, and the hose off
the old washer that I used to extend it, meet. Wondering if the diameter
at that joint is too small. At the time I made the hose, it didn't look
any smaller than the inside of the corrugations(or the output pipe of
the washer), and has worked 'okay' for five years. I did dig up the
owner's manual, both real and online. (RTFM, what a concept), and it
claims drain can be up to 8 feet/2.5 meters higher. At 80 inches, I
should be well within that range.
Mebbe I'll stop by the appliance repair place tomorrow after work and
ask them, and see if they have a proper extended-length hose. These
entry-level big-box-special GE laundry items don't seem to have a very
good rep, from what I understand. Perhaps there is a common failure
point in the plumbing under the tub that they are aware of. My gut says
there is something clogged/cracked/loose inside the washer.
