I think the problem is in _determine_cmap_params:

https://github.com/pydata/xarray/blob/95e4f6c7a636878c94b892ee8d49866823d0748f/xarray/plot/utils.py#L262

This may have to be: python if levels is not None:

Introducing this change does not break any test (py.test xarray/tests/test_plot.py) and runs your example successfully. However, it then causes the same problem as in #3744.
