You are halfway through a job when the xTool P3 suddenly stops with an air pump warning. The log shows a code like AIRPUMP.ELEMENT_ABNORMAL.PUMP_TEMP_HIGH: the pump has overheated, and the machine protects itself by stopping. It’s alarming, but it’s almost always resolved with four checks in order.
This guide adapts the xTool support documentation about the P3 air pump temperature error into Spanish, explaining what we do when it happens.
What the error is telling you
The air pump moves the airflow that evacuates smoke and dissipates heat. If the pump itself exceeds its safety temperature (around 75 °C), the machine stops the job to avoid damage. The warning is not the problem itself: it’s a symptom that the pump is not dissipating its own heat properly. Possible causes:
- Firmware or software not updated.
- Overheating from many continuous hours of work.
- Failure of the pump’s exhaust fan.
- Pump failure.
1. Update firmware and software
Bring xTool Studio and the firmware up to date and restart the machine. This is the first official step and rules out a false positive that has already been fixed.
2. Check the filter
A dirty pump filter is the most common mechanical cause: it chokes the pump’s breathing and causes it to overheat. Remove the left side cover, take out the filter grille, and inspect it:
- Dirty → clean or replace it. You can follow the step-by-step in the filter guide.
- Clean → proceed to step 3.
3. Let it cool down
After long cutting sessions, the pump can exceed 75 °C and trigger the warning simply due to heat buildup. If this is your case—you’ve been running it for hours—pause the job and wait for it to cool before resuming. It’s not a failure: it’s the machine protecting itself. For long workdays, plan breaks or improve room ventilation.
4. Check the exhaust fan
The pump has an exhaust fan that expels its heat. If that fan doesn’t spin, the pump overheats even if the filter is clean and you haven’t been running it for so long.
With the left side cover removed and the filter out, observe the fan during a process:
- Spins normally → the fan is not the problem; if the error persists, it’s the pump and you should contact support.
- Does not spin → turn off the machine, remove the side panel, and check the fan cables (a loose connection is the most common issue). If the wiring is fine and it still doesn’t spin, the fan or pump need technical service.
Frequently Asked Questions
It always happens during long jobs. Is that normal?
If the filter is clean and the fan spins, it can be heat buildup: the pump reaches its limit in very long sessions. Taking breaks, improving room ventilation, and avoiding continuous cuts at maximum power without rest helps.
Can I keep using the machine if I dismiss the warning?
Don’t force it. The warning protects the pump; ignoring it repeatedly can lead to a real failure and a replacement. Let it cool and fix the cause.
Is it related to my cuts coming out burnt?
Yes, they share a root cause: a dirty filter or a choked pump lowers airflow, which causes both yellowed edges and temperature warnings. If you have both symptoms at once, start with the filter.
