E130
Baxi E130 on a gas boiler: flue NTC sensor overheat
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
Baxi E130 means the flue NTC sensor has detected overheating. Check the flue terminal from outside, reset once by holding reset for at least 2 seconds and, if it returns, call the service centre. If you smell combustion fumes, switch off and ventilate.
Safety first
Stop and check this first
- If you smell combustion fumes: Baxi says to switch the boiler off, ventilate by opening doors and windows and call the service centre. Carbon monoxide has no smell; if anyone has a headache, dizziness or nausea near the boiler, get outside and seek medical help.
- If you smell gas: Baxi says to switch the boiler off, not to operate any electrical device or switch on lights, to put out any flame and open the windows. Then leave the home and call your gas distributor's emergency line and the service centre from outside.
Safe checks you can perform
- Combustion smell and flue terminal
- Pressure on the gauge
- One reset with the reset key
- Combustion check by the technician

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Flue sensor reading
What they doThe technician compares the flue temperature in item 07 with an independent measurement at the flue test point.
They must show youboth temperatures.
In writingthe sensor's condition and whether it was replaced.
Combustion analysis
What they doThe technician measures CO2, CO and flue temperature with an analyser and compares them with the maker's values.
They must show youthe analyser printout.
In writingthe values and what was adjusted.
Heat exchanger and flue check
What they doThe technician checks the primary heat exchanger and the flue duct.
They must show youthe condition of both.
In writingthe cleaning or repair done.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Combustion smell and flue terminal
- Who:
- you.
- How:
- notice any smell of burnt gases and look at the flue terminal from the ground, without touching it.
- Result that matters:
- whether there is a smell or the terminal is covered.
- If there is a smell:
- switch the boiler off, ventilate and call the service centre.
- If the terminal is covered:
- do not reset; call the service centre.
- Evidence to keep:
- photos of the terminal and a note of the time.

Pressure on the gauge
- Who:
- you.
- How:
- with the system cold, check the gauge reads 1 to 1.5 bar, as Baxi asks.
- Result that matters:
- whether pressure is correct.
- If it is low:
- top up slowly with the filling tap and bleed the radiators, as Baxi describes.
- If it is correct:
- lack of water does not explain 130.
- Evidence to keep:
- a photo of the gauge.

One reset with the reset key
- Who:
- you.
- How:
- hold the reset key for at least 2 seconds, as Baxi says for 130. Baxi allows 5 consecutive resets and then a 15 minute wait: do one.
- Result that matters:
- whether the boiler heats again without the code.
- If it works:
- note the date; if it repeats, call the service centre.
- If 130 returns:
- do not keep trying; call the service centre.
- Evidence to keep:
- a photo of the display and a note of each reset.

Combustion check by the technician
- Who:
- authorised gas technician.
- How:
- checks the flue sensor, the heat exchanger, the flue and combustion with an analyser.
- Result that matters:
- why flue gases are hot.
- If the sensor fails:
- it is replaced.
- If the sensor reads correctly:
- the cause of overheating is corrected.
- Evidence to keep:
- a report with readings and what was corrected.
Baxi says to call the authorised service centre: opening the boiler or touching the gas line or flue is not the user's job.

What it means
On the Platinum Compact ECO, code 130 is the flue NTC sensor tripping on overheat, and Baxi allows a reset by holding the key for at least 2 seconds. The sensor measures combustion gas temperature, which you can see in the information menu (item 07). Flue gases that are too hot mean heat is not passing properly to the water or combustion is not normal. The code does not say the cause or whether the sensor itself fails.

Symptoms and causes
Probable causes · in order
- Heat not passing well to the waterPossible
If 130 appears after heating for a while and pressure is low or there is air, the heat exchanger gives off less heat and flue gases leave hotter.
Evidence: Baxi Platinum Compact ECO, instrucciones de funcionamiento y mantenimiento para el usuario
- Abnormal combustion or dischargePossible
If the terminal is covered or there is a combustion smell, flue discharge or combustion is not normal; the technician checks it with an analyser.

- Faulty flue sensorLess common
If item 07 shows an absurd temperature with the boiler cold, it points to the sensor or its connection.
