Though regards hose up high to spigot - I agree it makes sense, but is it? If the waste outlet at the back of the appliance is at the rear bottom then whether it gets pumped low and then up into spigot as opposed to high and across into the spigot, is there much of a difference?
Every washing machine and dishwasher "won't drain" I attend, the hose runs under the units and up to the spigot.
They clogg up with particles that build up over time and can eventually kill the pump.
