LG Dishwasher Error Code bE
The machine has detected a tub full of foam, which usually means the wrong detergent went in — hand dish soap is the classic — or far too much of the right one. Foam confuses the sensors and can push water toward the base. The good news is this is the most fixable code on the list and needs no parts.
Common causes
- Hand dishwashing liquid used instead of dishwasher detergent
- Too much detergent, or rinse aid spilled in the tub foaming up
- Heavy pre-rinsing with soapy water leaving residue on dishes
- Machine not level, letting sudsy water reach the leak sensor
What to check, in order
- Open the door slowly and confirm the tub really is full of foam before doing anything else
- Scoop out what suds you can, then run a rinse or quick cycle with no detergent to flush the rest through
- Check what detergent was used and switch to automatic dishwasher detergent at the dose on the pack
- Check the machine is level with a spirit level and adjust the feet if it leans
- If bE returns with the right detergent and a level machine, have the leak sensor checked
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 at the tap.
- 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 bE, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Parts that may be involved
Leak sensor (if falsely triggered)
Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
