Owner fix

Before you call Cuisinart

Refill and re-seat the water tank, and straighten any inlet or drain hose you can reach.
Run the descale program if the oven has one, with the manufacturer's descaler, not vinegar.
Switch the oven off at the wall for a minute and back on. One power-cycle is in nearly every manual; repeated resets are not.
If the same code returns, note it with the serial number and book service. Every sensor, probe, fan or board code above is listed by Cuisinart as a service call.
