I am in the same boat as the two other complainants on this site. My DCS stove has not worked properly for more than a year. The simmer burners have been fluttering for longer than that, and now the ignition system never stops clicking as long as a burner is turned on. It is maddening. Also, the burners are advertised as being sealed. Yet, there is not a single gasket between them and the stove top. I have used minimal amounts of water to keep the top clean, but it has still seeped underneath, and the entire undercarriage of the stove top is rusted out. Ignition wire connectors have rusted away, and I can only really use the two rear burners--on a $4000 stove that is only three years old!!
Service has been horrible, as well. The Fisher & Paykel customer service people have lovely British accents, but are totally useless. I have finally gotten them to offer to pay for replacement parts, but no labor. My local repair company (Earl B. Feiden, Kingston, NY) has been pretty useless as well, but that's somewhat off-topic.
Thing is, even if the new parts are installed, with me paying for labor, the stove will end up in the same condition very soon. Unless, of course, I never clean it. I am disappointed and saddened by this. Please do not buy anything from DCS, and by association, Fisher & Paykel.
