Hi,

I disconnected the hose as you suggested and ran the drain cycle.

It appears the drain motor isn't strong enough to pump the water up
above about the level of the main basin, or slightly above. This is
far belw the ~3feet or so of the water level in the drain pipe in the
wall. This suggests a bad drain pump motor assembly. However, the
motor impedance reads 16.5 ohms just like it should (according to the
repair guide for this particular model).

Do you think it's more likely to be a mechanical problem in 1) the
motor or 2) the pump assembly? Eg impellor broken, bearings, gunk,
etc. I have convinced myself it's not electrical.

thanks
Michael
