MCZ A01 pellet stove: failed ignition, flame did not light
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
Your MCZ pellet stove shows A01 FAILED IGNITION: no flame formed at start-up. Check the pellet level and how the brazier sits while the stove is cold and unplugged; if it fails again, stop using it and call the technician.
Safety first
Stop and check this first
- Never load pellets into the brazier by hand, neither before ignition nor while running; the MCZ manual forbids it because an overloaded brazier produces abnormal smoke.
- If smoke appears in the room during ignition, open the windows, switch the stove off with the panel button and not the rear socket button, keep the fire door shut and move away until the smoke clears.
Safe checks you can perform
- Read A01 on the panel and check the pellet level
- Inspect and clean the brazier with the stove cold and unplugged
- Clear the alarm from the panel once and watch a single start-up
Leave these tasks to a qualified professional
- Do not attempt this professional task: Glow plug and stove operation check by the technician
- Do not attempt this professional task: Review of the air inlet, smoke outlet and chimney
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.
Glow plug and stove operation check by the technician
What they doA qualified MCZ technician checks that the glow plug heats up and that the product operates correctly after repeated failed ignitions, without the owner handling internal components.
They must show youthe glow plug heating test and the state of the brazier and its base before the job is closed.
In writingthe A01 code recorded, what was checked on the glow plug and the conclusion about the cause of the failure.
Review of the air inlet, smoke outlet and chimney
What they doThe technician verifies that the combustion air inlet and smoke outlet are fitted correctly and working, and inspects the chimney when ignition keeps failing.
They must show youthe condition of the air inlet, smoke outlet and chimney after the review.
In writingany installation anomalies found, if any, and what was corrected or recommended.
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.
Read A01 on the panel and check the pellet level
- Who:
- you, looking at the graphic panel of the MCZ stove and at the pellet hopper.
- How:
- confirm that the crown is red with code A01 and the text FAILED IGNITION, and look at how many pellets remain in the hopper; if it is nearly empty, refill only with the certified good quality pellets the manual asks for.
- Result that matters:
- rule out a lack of fuel, the first thing the manual asks you to check for A01.
- If the hopper was empty or nearly empty and you refilled it:
- move on to the brazier review before lighting again.
- If there are plenty of pellets in the hopper:
- go on to inspect the brazier with the stove cold.
- Evidence to keep:
- photo of the panel showing A01 and of the pellet level in the hopper.

Inspect and clean the brazier with the stove cold and unplugged
- Who:
- you, only with the stove completely cold and the cable disconnected from the 230 V socket.
- How:
- check that the brazier rests in its seat with no play, use the supplied brush to remove deposits and unburnt pellets, clear the support base and put the brazier back in its working position; never load pellets into the brazier by hand.
- Result that matters:
- leave the brazier clean and properly seated before any new start-up attempt.
- If the brazier was dirty or misplaced and is now corrected:
- go on to clear the alarm from the panel.
- If the brazier was clean and well seated:
- do not keep trying and contact an authorised service technician.
- Evidence to keep:
- photo of the clean brazier seated in its support.

Clear the alarm from the panel once and watch a single start-up
- Who:
- you, in front of the MCZ stove now cold and with the brazier checked.
- How:
- hold the panel button for at least 3 seconds to reset the alarm, as the manual says, and launch one single ignition without putting pellets in the brazier; if A01 shows again, do not retry any more times.
- Result that matters:
- see whether a simple cause was fixed without forcing repeated start-ups.
- If the flame forms and the stove starts normally:
- pay attention to how the next start-ups behave.
- If A01 appears again:
- stop using the stove and call a qualified technician.
- Evidence to keep:
- outcome of the single start-up and whether the A01 code shows up again on the panel.

What it means
In part 2 of the MCZ installation, use and maintenance manual for the EGO AIRMATIC 8 XUP! M3 CORE stove (chapter 37, alarms), A01 FAILED IGNITION means the flame does not ignite during the start-up phase. Other MCZ models may differ, and this code alone does not prove that the glow plug, the feed screw or any other part is faulty.
Warnings and stop conditions
- Highsource verified
Never load pellets into the brazier by hand, neither before ignition nor while running; the MCZ manual forbids it because an overloaded brazier produces abnormal smoke.

Symptoms and causes
Probable causes · in order
- Low pellet level in the hopper or too little reaching the brazierCommon
The first check in the table is the pellet level in the hopper; the manual adds that on the first ignition an empty feed screw may not fill the brazier in time.
Evidence: Installation, use and maintenance manual EGO AIRMATIC 8 XUP! M3 CORE - Part 2 Operation and cleaning (Code 8902515200)
- Brazier badly seated, with deposits or unburnt materialCommon
The manual asks you to check that the brazier sits correctly in its seat and is clean, and warns that blocked holes or a deformed brazier from poor maintenance cause delayed ignition.
Evidence: Installation, use and maintenance manual EGO AIRMATIC 8 XUP! M3 CORE - Part 2 Operation and cleaning (Code 8902515200)
- Glow plug that does not heat up or an installation problemPossible
The table includes making sure the glow plug warms up, and the manual says that if the brazier is fine but nothing lights there may be a component problem or an incorrect installation.
