Beko F L t fault codewhat it means and how to fix it
The only alphanumeric message a Beko dryer shows. It means the filters need attention, and Beko give five things to check — including two most owners do not know exist.
Take care
What F L t means
This is not a fault code, and there is no engineer branch in Beko’s answer to it. Every step they give is something the owner does. What makes it worth a page is that Beko document it in exactly one place — the troubleshooting chapter — and leave it out of the symbol legend, the warning indicators section and the control panel key.
So the one message an owner is most likely to look up is the one thing the reference sections of their own manual do not list. Their answer has four branches and the useful thing about it is how many separate filters are involved. There is the internal filter and the external filter, and Beko note that if your machine uses both as a double filter in the cover area you need to make sure both are actually installed.
There is the eco-friendly filter, which has a cloth element that clips into a plastic frame, and Beko specifically ask you to check the cloth is attached — because it can be refitted as a bare frame that looks correct and filters nothing. And then there is the area in front of the condenser, behind the kick panel at the bottom of the machine, which is where the lint that got past everything else accumulates. That last branch cannot apply to a vented machine, and consistently with that the message does not appear in vented manuals at all.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| The internal or external filter is dirty | The first thing Beko name. Ordinary lint on the filters in and around the door, expected after every load, and the reason the message exists in the first place. | Common |
| One of a pair of filters is missing | Beko flag this explicitly for machines with a double filter in the cover area. It is easy to clean both and refit one, and the machine notices the difference in airflow even though the panel looks normal. | Common |
| The area in front of the condenser is blocked | Behind the kick panel at the bottom front. This is where fibre that escaped the filters collects, and it is the part of the machine most owners have never opened. On a heat pump model Beko say the metal surface of the condenser "must be checked at least every 6 months" and has its own blinking icon; on a condenser model the condenser unit comes out for rinsing. | Common |
| The eco filter cloth is not attached to its frame | The eco-friendly filter is a cloth element in a plastic carrier. Refitted without the cloth it looks entirely convincing and does nothing at all, which is why Beko write a whole branch about it. | Occasional |
What to try yourself
Take the washing out and spread it before you start. Beko’s own safety guidance is that a load left heaped in a stopped drum can keep heating for hours.
Clean the inner and outer filters, or replace the eco-friendly filter if that is what your machine uses.
If your machine takes a double filter in the cover area, check that both are actually installed rather than just one. Beko name this as a separate branch for a reason.
If you use the eco-friendly filter, check the filter cloth is attached to the plastic part and fit it if it is not. A bare frame looks right and filters nothing.
Open the kick panel at the bottom front and deal with the area in front of the condenser. Beko call this the toe board or kick zone, and their Maintenance and Cleaning section gives a different procedure for each machine type. On a condenser dryer (Beko’s B3T41011D manual): let the machine cool with the door open, open the kick plate, unlock the two condenser locks, pull the condenser out, clean it with pressurised water from a shower head and let it drain, then put it back in its housing, fasten both locks so they are seated securely and close the kick plate.
On a heat pump dryer (Beko’s BM3T31023 manual, and Blomberg’s LTDIP08310) the condenser does not come out. Open the toe board by pulling its button, move the latches to open the air deflector lid, and slide the cleaning brush off the deflector to the left. Clean the fibre off the metal surface of the condenser with a damp cloth or that brush, working up and down only — Beko say cleaning left to right damages the metal plates. A vacuum cleaner is fine if it has a brush attachment and not recommended without one. Water in the plastic section in front of the condenser is normal. Slide the brush back and lock it, refit the air deflector cover, close the latches and the toe board.
Beko: "You can clean by hand, provided you wear protective gloves. Do not try to clean with bare hands. The condenser fins may damage your hands."Refit everything dry and properly seated, then start a short programme. If F L t returns with all of that genuinely clean, that is the point at which it is worth calling — but check the eco filter cloth once more first, because it is the branch people skip.
Get a qualified appliance engineer to look at your Beko F L t
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.

Nothing in almost every case, since this is filter cleaning. An eco filter cloth is an inexpensive consumable. Beko publish no call-out charge for dryers, so any repair figure is an independent market estimate.

Common questions about Beko F L t
My display shows FLT, or F Lt. Is that the same thing?
Yes. Beko render it inconsistently across their own manuals — with spaces, without, and with different capitalisation — and the display adds its own variation. Treat F L t, F Lt, FLT and FLt as one message.
Is it a fault? Should I call someone?
It is not a fault. Every branch of Beko’s own answer is something you do yourself, and there is no "contact service" step in it beyond the generic line that closes the whole troubleshooting chapter. Work through the filters first.
Why is it not in the symbol list in my manual?
We do not know, and it struck us as odd too. Beko document this message only in the troubleshooting chapter and omit it from the symbol legend, the warning indicators section and the control panel key. If you looked it up in the reference part of your manual and found nothing, that is why.
My older Beko has never shown this.
It would not. The message belongs to the current display generation — it appears in none of the older Beko manuals we examined, none of the Blomberg condenser manuals, and not in the vented machine. If yours predates it, your dryer signals filter problems with a lamp instead.
Does this apply to my Blomberg?
Identically, and we can be unusually confident about that. The F L t passage in the Blomberg manuals is word for word the same as the Beko one, down to reproducing a missing space in Beko’s typesetting. That is the same document with a different badge, verified from Blomberg’s own published manual rather than from a service portal.
