My kohler 5ECD is shutting down and showing error code EC69. It will restart if reset and run for 15 to 20 minutes (varies) and shut down again. The manual says O2 switching fault, and I have been waiting for the kohler dealer to get back to me for at least 2 weeks now. Dealer says they are waiting for kohler tech support to advise. Has anyone seen this error code and been successful in resolving it. Grateful for some direction or advice.
