Beko Dishwasher E01 Error Code: What It Means and How to Fix It

Last updated: October 5, 2026 · Codes covered: E01, E:01, P1 · Sources

An E01 code on a Beko dishwasher means its leak protection has been triggered. The machine has detected too much water, or water in its base, and it will try to pump the water out. Sometimes the cause is simple and the code clears on its own. If it doesn't, Beko treats it as a fault for an authorized service technician, so don't keep restarting the machine.

Depending on your model and where it was sold, the code may show as E:01, E01, or a blinking P1 light.

What the E01 code means

Beko's manuals describe E01 a little differently depending on the region:

• US models (beko.com US manuals, e.g. DUT36522X): If the machine takes in too much water or there's a leak at any of its components, it detects this and flashes E:01 on the program indicator. While the overflow continues, a safety routine stays active and tries to drain the water. If the overflow stops and it's safe, E:01 goes away. If E:01 doesn't go away, Beko calls that a permanent fault and says to contact authorized service.
• UK models (e.g. BDIN16440): Beko calls E01 a "chassis water filling fault": water has got into the base (chassis) of the machine. On models without a full display, the P1 light blinks and the power LED flashes. The error routine starts and the cycle ends. If you see the error continuously, Beko says to cut the power, close the water valve, and contact authorized service.

Beko's UK manual also notes that error codes can change depending on the model. Check the troubleshooting table in your own manual. If you don't have it, look up your model number on Beko's website for your country.

E02 is a different code. E02 (E:02, or P2 on some models) means no water is getting in, usually a closed tap or a blocked inlet filter. That's the opposite problem.

Likely causes (most common first)

1. Too much foam. Regular dish soap or too much detergent makes suds that can spill over inside the machine. Beko says to use only dishwasher detergents, and no more than the packaging recommends.
2. Door not closing fully. If the feet aren't adjusted properly, Beko warns the door may not close completely. Water and steam can escape at the seal.
3. Loose or damaged hose connection. A leak where the inlet or drain hose connects, or a split hose, can drip into the base.
4. Blocked filters or a drain problem. Dirty filters and a kinked drain hose can let water back up and overflow inside.
5. Internal leak or overfill. A leaking pump, seal, or internal hose, or an inlet valve that won't shut off, needs a technician.
6. Faulty leak sensor (float switch) or control. Less common.

How to fix it, step by step

Try the dishwasher again after each step. If water is spreading across the floor, skip straight to step 1 and call for service.

1. Cut the power and close the water valve. That's what Beko's UK manual says to do if E01 keeps showing. Switch the dishwasher off at the plug or breaker, and close the supply valve (usually under the sink).
2. Give the safety routine a chance. On US models, Beko says the machine tries to drain the water and E:01 disappears once the overflow stops. If water is still draining, let it finish before you do anything else.
3. Check for water around the machine. Wipe it up and note where it seems to come from: the door, under the sink, or underneath.
4. Check the hose connections you can reach. With the power and water off, look under the sink at the inlet hose connection on the valve and the drain hose connection. Tighten anything loose by hand, and look for cracks or splits. Beko says the supply and drain hoses must be securely fastened and undamaged.
5. Check your detergent. Use only dishwasher detergent. Never use hand dish soap or laundry detergent. Don't use more than the packaging recommends. If you see suds inside, run a rinse-only or short cycle with no detergent once the code clears.
6. Check the door closes fully. Make sure no items stick out of the racks and get in the way of the door. If the door doesn't close firmly, adjust the machine's feet as your manual describes.
7. Clean the filters. Beko's UK manual says to clean the filters at least once a week. Twist out the micro and coarse filter group, pull out the flat filter, rinse all of them under the tap with a brush, and refit them until they click.
8. Check the drain hose. Make sure it isn't kinked, crushed, or blocked where it connects under the sink.
9. Restore power and water. Open the valve fully and check for leaks. Turn the machine back on and run a short cycle while you watch.
10. Stop if E01 comes back. Beko says a persistent E01 is a fault for authorized service. Don't keep restarting it.

Test the part

Most of the parts behind E01 (the base, the leak sensor, the pump and the internal hoses) sit behind the kick plate. Beko warns that removing the kick plate on free-standing and under-counter models voids the warranty. If your dishwasher is under warranty, stick to these outside checks and call Beko service.

1. Unplug the dishwasher and close the water valve.
2. Inspect the hoses you can see. Check the inlet hose and drain hose along their whole length under the sink for splits, bulges, or wet spots. Feel the fittings for drips.
3. Look for a wet floor under the front of the machine. Water there usually means an internal leak.
4. Out of warranty and comfortable with tools? The leak sensor is usually a float switch in the base. To test it, take off the kick plate, photograph the wires, and disconnect the switch. Set your multimeter to the lowest ohms setting and touch one probe to each terminal. PartSelect says you should read zero or infinity ("OL"), and pressing the switch or lifting the float by hand should flip the reading to the opposite extreme. A switch that doesn't change has failed.
5. Check the float moves freely. Debris or a stuck float can hold the switch on. Readings and layout vary by model, so use your model's wiring diagram to identify the terminals.

If the switch works and the base is dry but E01 comes back, stop and call a pro. Tracking down an internal leak isn't a DIY job.

Safety notes

When to call a pro

Call Beko authorized service or a qualified appliance technician if:

• E01 (or E:01, or a blinking P1) doesn't clear, or keeps coming back.
• Water is leaking onto the floor.
• You see a damaged inlet hose (including an AquaSafe+ hose) or a cracked fitting.
• The machine keeps filling and won't stop.
• The dishwasher is under warranty. Removing the kick plate can void it.

Beko's manuals say to contact the authorized service agent. Use your manual or Beko's website for your country to find the right contact.
