Red Light Flashing on ECB
The unit won't operate at all - completely dead - with the ECB's red light flashing
Over heating
Take out the isolation key and wait 20 minutes to give the thermal fuse a chance to reset - the red light should stop flashing and the ECB shouldn't feel warm to the touch.

Green light flashing on ECB
The unit won't operate, or only moves on and off, with the ECB's green light flashing
Caravan battery low
Check the caravan battery's voltage with nothing switched on, at least 4 hours after it was last charged: about 12.7V or more is fully charged, 12.4V is roughly half, and 12.0V or less is flat. Charge or replace the battery as needed.

Reset the ECB: switch off the isolation switch, pull the key out for at least 20 seconds, then switch back on. The ECB's green light should then be lit.
DIY Safe
N/A
The unit's completely dead and won't operate at all
—
Confirm the green light is lit on the electronics. If it isn't, check the in-line fuse hasn't blown and that 12V DC is actually reaching the ECB.
DIY Safe
N/A
The unit won't operate, or operates on and off
—
Confirm the handset battery is reading the correct 9.5V - if both rows of red LEDs flash, the handset battery is getting low.
DIY Safe
N/A
The unit won't operate properly, or moves in a stop-start way
The battery terminals are poorly connected or corroded
Make sure the battery terminals are clean and properly connected.
DIY Safe
N/A
The caravan won't move, or only moves on and off
Caravan battery low
The caravan's battery is low - engage the rollers, move the caravan, and check how far the battery meter drops. If it drops below 12V, have an accredited supplier test the battery, then charge or replace it as needed.
DIY Check / Tech Fallback
N/A
Rollers slip on wheels
—
Disengage the rollers from the tyres - the gap should be roughly 19mm. Also check the tyre treads aren't badly worn and that tyre pressures are correct.
