Drain/spin works only with water at low level

Drain/spin works only with water at low level

Model 110.28803890, wouldn't drain, had excessive suds, bailed sudsy water manually/repeatedly until rinse ran clear, still wouldn't drain the last bit of water, left it overnight, miraculously the drain/spin worked the next morning. Recreated this process a second time with the same result. It's as if it works once something dries perhaps? Thank you!
