Battery-related problems
| Problem | Possible cause | Solution |
| My modular battery is depleted very quickly. | You might have combined segments with different charging levels in one battery. Now, at least one battery segment might be locked. | Make sure, all battery segments have been inserted correctly into the battery hull. Fully discharge and re-charge the complete battery. |
| My scooter behaves strangely: I can use it in lower gears, but it turns off when I select a higher gear. | You are not getting the full battery power, because at least one battery segment has a lower charging level than the others (blocked segment). | Make sure, all battery segments have been inserted correctly into the battery hull. Fully discharge and re-charge the complete battery. |
| I fully discharged and charged my modular battery, but the capacity displayed on my scooter control module does not seem to match. | If you are using your scooter in very cold environments, it is a physical property of Li-Ion batteries, that their capacity will be reduced. This process is reversible: As soon as the battery has warmed up (e.g. due to changing ambient temperature), its capacity will be restored. | |
| The battery will not charge. | The battery is not connected to the charger. | Check the safety disconnector inside the scooter. |
| The battery voltage is too low. | Measure the voltage at the battery terminals. If it is lower than specified as minimum for the type of battery, contact the service. | |
| The battery is damaged. | Contact the service. |
Hardware-related problems
| Problem | Possible cause | Solution |
| The scooter will not start | Safety disconnector not installed. | Check the safety disconnector. |
| The motor does not run or runs unevenly | The motor is dirty or blocked. | Turn off the scooter, remove the propeller, remove impurities or cause of blockage in accordance with the instructions contained in the manual. |
| Water inside the scooter housing | Damaged seals. | Remove the old seals, clean the seal surroundings and contact areas of the sealed parts, replace with new seals, grease with lubricant recommended by the manufacturer. |
| Deformation of the housing elements. | Replace the deformed housing element. | |
| Condensation caused by fluctuations in temperature and humidity. | Take the scooter to a dry place. Disassemble the scooter and dry individual components. Do not use the scooter at low temperatures if it was previously assembled in warm and humid conditions. If this is not possible, disassemble scooter earlier so the moisture can evaporate. | |
| Problems with control elements | Dirty or blocked control elements. | Rinse the control elements (buttons on the steering handle) thoroughly, wash and wipe with a dry cloth. |
| The scooter sinks or rises towards the surface | Incorrect weight and / or poor placement of the ballast. | Improve the selection of the weight and the distribution of the ballast. If you have problems balancing and trimming, it is recommended to use an external ballast. |
| Underwater, the handles of my scooter do not point upwards. | The placement of the battery segments plus the sum of trim weights does not lead to creating a “keel” for the scooter. |
Error codes
In case of internal malfunctions, the scooter will display an error code by means of the red LED in the bottom left corner of the display:
Error code displayed
The codes are displayed in morse code style by means of long blinking intervals (approx. 1200 ms) and short blinking intervals (approx. 200 ms).
Caution!
If an error code is displayed, contact your Seacraft reseller, the local distributor, or create a service ticket.
The following error codes may be displayed
(— = long interval, . = short interval):
| Blinking code | Meaning |
| . . — | Overvoltage |
| . — . | Undervoltage |
| . — — | Max. temperature exceeded |
| — . . | Startup UP error |
| — . — | Speed feedback error |
| — — . | Overcurrent |
| — — — | Undefined malfunction |
