Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Measurement result flashes | Battery is low (measurement is still possible). | Prepare to replace the 9V battery soon. | DIY Safe |
Operational Fault | Battery is empty (measurement is no longer possible). | Replace the battery with a new leak-proof 9V E-block (6 LR 61, 6 F 22) battery. | DIY Safe |
Operational Fault | No liquid gas detected at the measuring point, or measurement error caused by dirt, rust, thick paint, stickers, condensation, or unsuitable cylinder type. | Clean the measuring head and cylinder surface, remove stickers or condensate, or try measuring at a different height on the cylinder. | DIY Safe |
Operational Fault | No liquid gas detected at the measurement point or measurement error due to dirty head, rust, thick paint, stickers, or frozen condensation. | Clean the measuring head, remove dirt/adhesives, or take a measurement at a different point on the gas cylinder. | DIY Safe |
Flashing reading indicator | Battery is almost depleted, though measurements can still be performed. | Prepare to replace the 9V battery. | DIY Safe |
Operational Fault | Battery is completely exhausted and no further measurements can be performed. | Replace the 9V battery (type 6 LR 61, 6 F 22). | DIY Safe |
Displayed measuring result flashes | The battery is low. | Measurements can still be taken, but the battery should be replaced soon. | DIY Safe |
Operational Fault | The battery is empty. | Measurements can no longer be taken; replace the battery. | DIY Safe |
Operational Fault | No liquid detected or inaccurate measurement caused by cylinder conditions (rust, thick paint, stickers, condensation, or indentations). | Clean the gas cylinder or take the measurement at a different point. | DIY Safe |
Operational Fault | Battery weak | Measurement is still possible, but the battery must be replaced soon. | DIY Safe |
Operational Fault | Battery empty | No measurement possible. Replace the battery with a leak-proof 9V E-Block battery (type 6 LR 61, 6 F 22). | DIY Safe |
Operational Fault | No gas, faulty measurement, or flat battery. | Ensure the measuring head is clean and in full contact with the cylinder. If the red status LED flashes and 3 beeps sound, the battery is flat; replace the battery. | DIY Safe |
Measurement result flashing | Battery low (measurement still possible). | Replace the battery as soon as possible. | DIY Safe |

It is suitable for all steel or aluminum propane/butane LPG cylinders with a diameter of 200 to 350 mm. It is not suitable for plastic gas cylinders, refillable tank cylinders, gas tanks, or butane camping cylinders (Campinggaz).
Q: How do I correctly perform a fill level measurement?
Clean the measuring head with a damp cloth, press the measuring head horizontally against the gas cylinder (do not drag it along the cylinder), wait for the beep and status LED result, and take multiple individual measurements at different heights from bottom to top.
Q: What battery type does the device require?
Use only leak-proof 9V E-block batteries (type 6 LR 61, 6 F 22).
Q: Which types of gas cylinders are compatible with the Truma LevelCheck?

Q: How is a measurement performed correctly?
Press the measuring head horizontally (at 90°) against the gas cylinder (confirmed by a beep). During measurement, the status LED flashes orange, and completion is indicated by another beep and the status LED reading.
Q: Which gas cylinders are compatible with the LevelCheck?
It is suitable for all propane / butane LPG steel or aluminium gas cylinders with a diameter of 200 to 350 mm. It is not suitable for plastic gas cylinders, tank gas cylinders that can be filled, gas tanks, or butane gas cylinders (camping gas).
Q: How do you determine the filling level?
Take several individual measurements at various heights on the gas cylinder from the bottom to the top. Do not drag the device along the gas cylinder.
