Sprayer does not run at all | Check transducer or transducer | 1. | Set sprayer to OFF and disconnect power to |
| connections (control board is not |
| sprayer. |
Digital display shows E=03 |
| ||
detecting a pressure signal). |
|
| |
| 2. | Check transducer and connections to control board. | |
|
| ||
|
| 3. | Disconnect transducer from control board socket. |
|
|
| Check to see if transducer and control board |
