Wolf Range burner problem
 

We had big coffee spill over the top of the range. I took everything apart and cleaned -- including holes in inner cap and soft dry toothbrush to igniter (per Wolf cust support). The burner outer ring lights, then immediately shuts off. The inner ring stays lit -- wildly -- but the igniter stays clicking. No igniter problems or flame issues with other burners. I have checked to make sure all parts are properly seated.

Before I call Wolf repair in, is there anything else I can do to troubleshoot? I know it's not the ring itself because I tried with different rings that work OK and no go.

Thanks
