Here are your parts
Parts for KESC307HBS - AppliancePartsPros.com
If you click on a parts picture often a new page will open with new info.

You seem to be missing a number at the end of the model number.
See the attachment for a tech sheet for a HBS3 unit.

The error is a shorted key.
Unplug the unit and the keyboard (console). Then plug the unit back in.
If the error is still there I would replace the microcomputer (control board/timer).
If there is no error then replace the console.
Make sure nothing can short out when you reapply power.

While apart I would try clean the connectors see below.
So also give a try with the console reconnected.
I doubt this will help as it is for an open ket not a shorted key error but is worth a try.

Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector. Use electronics contact cleaner or isopropyl alcohol.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
