Troubleshooting and error codes
| Error Type | Error mode | Checking Method | Corrective actions |
|---|---|---|---|
| Dry is not satisfied. (DW7933) | None | 1. Check whether Low Rinse LED light or not. | If Low Rinse LED light, refill rinse in Dispenser. |
| 2. Check the wire connections for the Dry Fan Motor. | Reconnect the Dry Fan Motor connectors. | ||
