Error codeFil-tEr

Signal on the display
The display flips between FIL and tEr while a buzzer sounds. That combination appears on Samsung heat-pump dryers and is a request to clean the heat exchanger.
Where the wording comes from
Samsung UK: the heat exchanger needs to be cleaned.
Samsung Russia, heat-pump list: a heat exchanger fault caused by dirt.
Your move
Clean the heat exchanger. If the signal is still there afterward, Samsung says to contact support for service.
When FIL and tEr persist after you clean, call (415) 969-6153 about Samsung dryer repair across San Francisco and the Bay Area. Give the code, the model number and a short account of the cleaning you carried out.
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
A buzzer with FIL and tEr alternating on the display means the heat exchanger of a heat-pump dryer needs cleaning.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
