Sharp steam oven error codes
8 codes for Sharp SuperSteam+ built-in oven SSC2489DS and Superheated Steam Countertop Oven SSC0586DS, transcribed from the official documentation with page references.
| Code | What it means | Likely cause | What to do | Service? |
|---|---|---|---|---|
| Fill water reservoir | Water reservoir level is low (SSC2489DS) | Insufficient water in the reservoir during a steam cook | Remove the reservoir, refill with fresh cold tap water (no distilled water) and reinstall | Owner fix |
| ATTENTION (oven needs to drain water) | The oven must drain water from its steam engine to reset itself (SSC2489DS) | Excess water in the SuperSteam+ engine or a steam function interrupted during operation | Make sure the reservoir is empty and in place; draining takes about 1 minute; then detach the reservoir and discard the water | Owner fix |
| Drip tray message | Drip tray missing or misplaced (SSC2489DS) | Drip tray not installed correctly | Remove and replace the drip tray correctly | Owner fix |
| CONTROL LOCK IS ON | Touch controls are locked (SSC2489DS) | Control Lock enabled | Unlock per p. 21 of the manual | Owner fix |
| DEMO icon / display counts down quickly | Oven is in Demo Mode and will not heat (SSC2489DS) | Demo Mode enabled | Cancel Demo Mode per p. 21 | Owner fix |
| Display flashes | Power was interrupted (SSC2489DS) | Power failure | Press Clear and reset the clock; if the oven was in use, reset the cooking function | Owner fix |
| D | Demonstration mode is set (SSC0586DS); cooking time counts down very rapidly and food is not heated | Demonstration mode, mainly for retail display | Press and hold CANCEL/OFF until it beeps, then press it 4 times | Owner fix |
| C + number | Error mode (SSC0586DS) | Not stated in the manual | Any time C with any number appears, the servicer should be called; disconnect the plug and contact a Sharp Authorized Servicer | Call service |

Before you call Sharp
- 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 Sharp as a service call.
