Beko Dishwasher Error Code E01
The machine has taken in too much water, or the anti-flood system has found water where it should not be, so the safety routine runs the drain pump and stops the programme.
Also shown as: E1
Applies to: Beko dishwashers with a display, DFN and BDFN series models
Common causes
- Internal leak from a hose, seal or the sump
- Inlet valve stuck open, overfilling the machine
- Heavy foaming tripping the level system
- Faulty float switch
What to check, in order
- Switch the dishwasher off and close the water tap.
- Check under and around the machine for water, and look inside for standing water above the filters.
- Clean the filters — heavy foaming from the wrong detergent can trigger the overflow sensing.
- If E01 returns with no visible leak, the float switch or the inlet valve needs testing — a technician job.
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
- Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
- If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E01, your model number (on a label on the edge of the door) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label on the edge of the door — and match the part to that number before ordering.
