Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
Remote control LED flashes for approx. 10 seconds then switches off | 13-pin safety plug is not connected to the safety socket or radio link to control unit could not be established. | — | Ensure the 13-pin plug is securely inserted into the safety socket on the caravan and perform a reset if needed. | DIY Safe |
Caravan battery warning flashes every 3 seconds | Caravan battery charge is weak. | — | Finish manoeuvring as soon as you can, then charge the battery. | DIY Safe |
Caravan battery undervoltage - flashes 5 times a second (5Hz) | Battery voltage is low (below approx. 11 V), locking the movement function. | — | Wait for battery recovery or charge the battery until voltage exceeds 11 V (disengagement of rollers remains possible below 11 V). | DIY Safe |
Overcurrent or overtemperature - flashes roughly twice a second (2Hz) | System has experienced overcurrent or overtemperature. | — | Switch the remote control off and back on. If it's overheating, wait for it to cool down first. | DIY Safe |
LED 'winks'/flashes with acoustic signal: 5 times per second (5 Hz) | Caravan battery undervoltage. Drive function is locked. | — | Wait for battery voltage to rise above approx. 11 V (e.g., via recovery or recharging). Retracting rollers is still possible below 11 V. | DIY Safe |
LED 'winks'/flashes with acoustic signal: approx. 2 times per second (2 Hz) | Overcurrent or excessive temperature. | — | Switch the remote control off then back on. If it's a heat issue, wait for the unit to cool first. | DIY Safe |
The LED flashes with a audiable sound for roughly 10 seconds after switching on, then goes off | 13-pin plug is not plugged into the safety socket, or radio connection to the control unit could not be established. | — | Check that the 13-pin plug is securely inserted into the safety socket, check batteries, or perform system reset. | DIY Safe |
Frequently Asked Questions
Q: What is the difference between the Mover SE R and TE R?
The Mover SE R is built solely for single-axle caravans up to 2000kg gross weight; the Mover TE R is for dual-axle caravans up to 2250kg.
Q: How far should the disengaged drive rollers sit from the tyres?
To work properly, the disengaged drive rollers must sit exactly 20mm from the tyres.
Q: Is it OK to tow the caravan with the mover's rollers engaged?
No - towing with the drive rollers engaged risks serious damage to the tyres, towing vehicle, and drive assemblies.
Q: What should I do if the electrical disengagement fails due to a discharged battery?
Prise off the plastic cap at the rear of the engagement motor and use the supplied socket wrench (WAF 7) to turn the hex bolt anti-clockwise for a manual emergency disengagement.
