I would doubt it as the error points to a ketpad or control board problem.
Unfortunately the pin-out for the keypad is not available so it is difficult to check with a meter.
I would try the following first
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.
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.
If this does nothing then replace the kaypad.
If that does nothing then it is probably the control board.
With AppliancePartsPros if you do the cleaning and and some basic troubleshooting, they will allow you to return the keypad if it does not solve your problem.
Please see their return policy.
