Model number: crtr9300as0

Washer seems to just churn and churn, but not draining, no high speed spin, no matter what cycle used (though seems to be fine every once in awhile). Checked tub-to-pump line, no blockages. Inspected drain pump, nothing blocking it, no damage to impeller. When it is called on to pump, seems to pump fine, just never seems to get the signal. Drain line not kinked or blocked. Checked incoming water lines and cleaned screens, no change. Going to try door lock relay next, but running out of ideas. Wife freaking out...

Can anyone help?
