Dacor ERD36SCH/H will not self clean

About 6 months ago I was cooking pasta on a front burner when the water boiled over. It must have seeped into the electronics below, because the range started to beep. The oven door lock made a grinding sound, and tried to lock the door. The display flashed F8. I finally got it to stop by turning off the power.

I successfully used the self clean cycle once after that.

The other day I tried to used the self clean cycle again, but the door latch makes the same grinding sound and the door will not lock.

Any suggestions?
