Sourced from Bailey's 2026 model year owner's manual. If your caravan is a different age or range, some details — such as the exact control panel brand or chassis-component generation actually fitted — may not match. Always cross-check against the handbook that came with your specific caravan.

Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Problems with the gas supply | Could be a nearly-empty gas cylinder, a closed cylinder valve, the hose rupture protection engaging, a triggered reset button, or a quick-acting shut-off valve closed on an appliance (heating, oven, gas hob, etc.) | Work through each possibility: how full the gas cylinder is, whether its valve is open, whether the hose rupture protection has engaged, whether the reset button has tripped, and whether every appliance's quick-acting shut-off valve is open. Contact Truma Service if none of that resolves it. | DIY Check / Tech Fallback |
Frequently Asked Questions
Q: What is the correct procedure for changing the gas cylinder on my caravan?
Start by making sure the old cylinder is actually empty, then shut the tap on the gas regulator followed by the cylinder's own valve and every gas appliance in the caravan. Disconnect the hose/regulator from the empty cylinder, undo the strap holding it in place, and lift it out of the gas locker onto the ground - fitting its plastic cap back on once it's out.
Before loading in the replacement, give the cradle and tray a quick check to make sure they're clean and debris-free (plain warm soapy water is fine for this), then take the cap off the new cylinder and set it into the cradle inside the locker. Reconnect the gas hose, refasten the retaining strap, then open the cylinder valve and relight your appliances one by one as needed.
