Samsung Air Purifier Error Code C105: Meaning, Checks & Repair
If a Samsung air purifier shows **C105**, the verified Samsung meaning in this research set is **wi-fi communication/module error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **C105**. Search normalization stores it as **C105** while preserving the characters a homeowner actually sees.

Quick answer
Wi-Fi communication/module error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so C105 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
If a Samsung air purifier shows **C105**, the verified Samsung meaning in this research set is **wi-fi communication/module error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **C105**. Search normalization stores it as **C105** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
While C105 is active, wi-Fi, Bluetooth, pairing, or network-related operation may fail.
Depending on the exact model, the appliance can work locally while connected features remain unavailable.
When the C105 condition is present, the code can appear during setup or communication with another module.
One clue that supports the C105 diagnosis is that c105 appears and the air purifier reports wi-fi communication/module error.
Why it happens
Possible causes
varies by model — official regional/current support — Wi-Fi communication/module error
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
As an external check for C105, confirm the appliance is in the correct pairing/setup mode for the exact model.
Before opening any service area, check the phone/app/network requirements in current Samsung instructions.
A safe owner-level check is to restart the network/app/appliance only in the documented order and avoid factory resets unless needed.
To rule out an accessible cause, unplug the air purifier for 30 seconds, reconnect it, and observe whether the code reappears.
Before opening any service area, if the code returns, Samsung directs the owner to request service.
Important safety warning. Disconnect power before cleaning or inspecting user-accessible components. Internal fan, sensor, and main-board work belongs in service. Do not bypass a safety device merely to see whether C105 disappears.

When to request repair service
If the appliance cannot establish or maintain the connection after supported setup checks, the communication module or control may require diagnosis. A repeatable C105 event is more useful diagnostically than repeated resets, because it shows when the wi-fi communication/module error check is failing.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **C105** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **C105** should not be ignored if performance is deteriorating or the display keeps returning.
Treat **C105** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Air Purifier C105** separate from same-looking codes used by other Samsung appliance families.
