Samsung heat pump dryers tell you what they need in plain words: check the filter, empty the tank, clean the heat exchanger. They are maintenance prompts, not faults, and Samsung publishes what each one means.
Ignore them for long enough, though, and they turn into slow drying, long cycles and eventually a service call. National Appliance Repairs services Samsung dryers across Melbourne, Sydney, Brisbane, Adelaide and Perth.
The messages Samsung lists
Samsung’s display and notification guide for its dryers covers these:
| Message | What it means | What to do |
|---|---|---|
| Clean the filter before use | A default reminder at power-on | Nothing. It disappears on its own |
| Check Filter | The lint filter needs checking | Make sure it is installed correctly, and clean it |
| Empty the tank | The water tank is full and the dryer has stopped | Empty the tank and refit it |
| Clean Heat Exchanger | It is time to clean the heat exchanger | Clean it as your manual describes |
| Check Heat Exchanger, continuing | The heat exchanger’s inner cover may not be fitted correctly | Open the cover, remove and refit it |
| Child Lock | Buttons are disabled except power and the lock control | Turn Child Lock off |
Samsung notes that the way some alarms are activated or turned off varies between models. Your user manual has the steps for yours.
Check Filter
Samsung’s guidance is to open the door, check the lint filter is installed correctly, and clean it if needed. A filter that has not been pushed fully home triggers the message just as a full one does.
Samsung recommends cleaning the lint filter before every load. That is the single habit that prevents most heat pump dryer problems, because fluff that gets past the filter ends up on the heat exchanger.
The “Clean the filter before use” message at power-on is not this alarm. It is a standing reminder and clears itself.
Empty the tank
A heat pump dryer condenses the moisture from your clothes into water. On models without a drain connection, that water collects in a tank. When it is full, the dryer displays Empty the tank and stops.
Empty it, push it fully back into place, and restart. Getting into the habit of emptying it after each load stops a cycle halting halfway. A tank that is not pushed fully home can trigger the same message even when it is empty, so if the alarm returns straight away, take the tank out and refit it firmly.
If your dryer is connected to a drain hose and still asks you to empty the tank, check that the hose is not kinked, blocked or raised too high.
Clean Heat Exchanger
This is the message that matters most for drying performance. The heat exchanger is where the dryer pulls moisture out of the air. When fluff coats it, air cannot pass through properly, and drying slows right down.
When the dryer displays Clean Heat Exchanger, follow your manual’s cleaning steps. Clean gently: the fins are thin metal and bend easily, and bent fins restrict airflow permanently. Do not use stiff brushes, sharp tools or compressed air.
If the alarm keeps showing as Check Heat Exchanger, Samsung’s guidance is to open the heat exchanger cover, remove the inner cover, and refit it correctly. A cover not seated properly keeps the alarm on.
Why your Samsung dryer is taking forever
If clothes come out damp or cycles run very long, check these before booking anyone:
- The lint filter, cleaned and correctly seated.
- The heat exchanger, cleaned gently.
- The water tank, empty and fully pushed in.
- The load size, within the program’s limit.
- The room. Heat pump dryers need reasonable airflow around them, and a cold, enclosed laundry slows them down.
- The washing machine’s spin. A faster final spin removes water far more cheaply than the dryer can.
When it needs a technician
Book if the clothes stay damp with every filter clean and the tank empty, if an alarm returns straight after you have dealt with it, if the drum does not turn, or if the dryer shows a numbered error code instead of a message.
The heat pump itself is a sealed refrigerant circuit. It is not something to open or test yourself.

Frequently asked questions
What does “Check Filter” mean on a Samsung dryer?
The lint filter needs checking. Make sure it is installed correctly and clean it. Samsung recommends cleaning it before every load.
What does “Empty the tank” mean on a Samsung dryer?
The condensed water tank is full and the dryer has stopped. Empty it, refit it fully and restart.
Why does my Samsung dryer keep saying Check Heat Exchanger?
Samsung’s guidance is to open the heat exchanger cover, remove the inner cover and refit it correctly. A cover not seated properly keeps the alarm on.
Why is my Samsung heat pump dryer not drying properly?
Usually a lint-coated heat exchanger or filter, a full tank, an overloaded drum, or a cold laundry. Check those first.
Is “Clean the filter before use” a fault?
No. Samsung describes it as a default message at power-on that disappears on its own.
The short version
Samsung dryer messages are maintenance prompts. Check Filter means clean and reseat the lint filter. Empty the tank means exactly that. Clean Heat Exchanger means the dryer is losing airflow, and it is the one that most affects drying time.
If clothes stay damp with everything clean, or a numbered code appears, it needs a technician. National Appliance Repairs services Samsung dryers across five capitals with upfront quoting. Book online or call your nearest office.
