How to check if ref. 998422 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 998422. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the extractor 998422 resolves.
The extractor evacuates the combustion gases with forced draft. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler attempts to ignite, you can hear the fan humming, and it stops with an ignition fault.
Cause: The air pressure switch does not detect the necessary depression because the fan does not spin fast enough.
With the boiler cold and unplugged, manually check that the impeller spins smoothly and without rubbing before replacing the part.
- 02
There is a smell of burnt gases in the boiler area or at the flue outlet.
Cause: The fan does not move enough air to complete the extraction of combustion gases.
Check the external terminal for any obstructions caused by dirt, insects, or a nest before considering the part as faulty.
- 03
A rubbing noise, squeak, or loud vibration is heard when the fan is running.
Cause: The impeller may be unbalanced or the motor bearings worn out from use.
Inspect the impeller with a flashlight: if you see accumulated dirt or notice it is off-center, clean it and test it before replacing the part.
- 04
The boiler doesn't even attempt to ignite; it remains completely dead as soon as heat is requested.
Cause: The fan motor may have an internal fault preventing it from turning.
Check if there is power at the fan connector before assuming that the part is faulty: sometimes the problem lies in the PCB or the wiring.
Fault codes for Ariston that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| A33 | Fan problem (lockout type A). | The Fime GR00540P fan does not start or spins out of range; the PCB detects absence/anomalous signal from the tachometer and locks. Check power supply to the fan, free rotation of the impeller, and Hall/tachometer signal to the PCB. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
