Error codeFil-tEr
ApplianceDryer
Quick answer
On a Samsung heat-pump dryer, FIL followed by tEr with a buzzer means the heat exchanger needs cleaning.
Model compatibility: Samsung reuses codes across series and model years, so Fil-tEr 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
Buzzer sounding; the heat exchanger needs cleaning.
When the display alternates FIL and tEr and the buzzer rings, a Samsung heat-pump dryer is asking for its heat exchanger to be cleaned. The entry covers heat-pump dryers.
What it means
Samsung UK lists the signal as “heat exchanger needs to be cleaned”, and the Samsung Russia heat-pump list describes the same code as a dirty heat exchanger.
What to do
Clean the heat exchanger. If the code remains afterwards, Samsung says to contact a service centre.
