Press ‘power’ button on front and ‘lock’ bottom at same time until you get p5 mode displaying ( it is in programming) mode.
Then press top left to ‘0’, bottom left panel to ‘0’, then press right bottom panel to 9, then press on ‘power’ button to save. This should take it off demonstration mode.

Try turning off the breaker for 10 sec and then try the unlock sequence

It's the showroom mode. Try the following workaround to deactivate it.

CT Induction Cooktop Error Code E13

wolf electric cooktop... several seconds after turning a burner on the unit goes to lock mode

I had that happen once and it went off after a day. I'd suggest maybe turning off the breaker and wait a few minutes and turn it back on. But here's my problem for you. I got the 30" model in March, 2008. The problem I've had is that the induction units cool down and start cycling when I'm cooking something like bacon, or pork chops etc., ie. where you're trying to brown something or sear. They cycle up and down every couple of minutes, so its really annoying. They work fine if I'm boiling water for pasta or sauces, etc. Have you experienced this. I've been working with the dealer and the company and they say its a "software" problem, but they've haven't taken them off the market. I use All-Clad stainless steel pans so that's not the issue. Thanks for your comments.
