Answer to continue safely

Is it safe to keep using?

Yes. Once the suds are cleared and the correct detergent is used, the dishwasher is completely safe to use. bE is a detergent-use error, not a mechanical fault.

Can I reset the code?

Yes. Cancel the cycle, clear the suds, run a rinse cycle to flush remaining detergent, and then restart a normal cycle with the correct detergent. The bE code clears automatically once the suds level is no longer detected.

When to stop immediately?

Stop if you notice: Suds are actively overflowing onto the floor — stop the machine and clean up to prevent slipping or water damage to flooring., bE appears repeatedly even when using the correct type and amount of dishwasher detergent, suggesting a faulty suds sensor..

Symptoms You May Notice

Foam or suds visible through the door glass

Thick white foam fills the bottom of the tub and may be visible through the door window — a clear sign that non-dishwasher soap or too much detergent was introduced into the wash cycle.

Water not circulating properly and spray arms sound weak

Excessive suds trap air in the wash pump, reducing water pressure to the spray arms — dishes may not be reached by the spray and washing performance drops significantly.

bE code displayed and cycle paused

The dishwasher halts the active cycle and displays bE, preventing further circulation of the foamy water until the suds level is reduced.

Soapy water or residue on the floor under the door

Heavy suds can squeeze past the door seal, leaving small puddles or dried soapy residue on the floor in front of the dishwasher.

Possible Causes

1

Hand dish soap or non-dishwasher detergent used

Liquid hand soap, laundry detergent, or general-purpose cleaners create extreme foam in dishwasher wash temperatures and pressures, triggering the suds detection circuit within minutes.

DIY Possible
2

Pre-rinsed dishes retaining hand soap residue

Dishes that were hand-washed or rinsed in the sink with dish soap and then placed directly in the dishwasher introduce enough surfactant to generate a significant suds event.

DIY Possible
3

Overfilled detergent dispenser

Using significantly more dishwasher detergent than recommended for the water hardness level can generate excess suds even with proper dishwasher-specific detergent.

DIY Possible

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Cancel the cycle and open the door slightly

    Press Cancel/Drain to stop the cycle. Wait for the machine to drain, then open the door a few inches and allow steam and suds to dissipate for 10–15 minutes before opening fully.

  2. 2

    Remove suds with a towel and rinse the tub

    Use a towel or sponge to scoop out as much foam as possible from the tub floor. Pour about 1 cup of clean water into the tub to dilute remaining detergent, then run a rinse-only cycle to flush the residue.

  3. 3

    Use only automatic dishwasher detergent going forward

    Check the detergent type. Only use powder, tablet, or gel detergent specifically labeled for automatic dishwashers. Use the amount specified for your water hardness — typically one tablespoon for soft water, more for hard water.

When to Call a Professional

Contact a qualified technician if:

  • bE persists after multiple cycles using the correct detergent at the correct dosage, confirming the suds sensor has likely failed.
  • The wash pump runs but water circulation is very weak even after the suds are cleared, suggesting pump damage from air-locking.
  • The error reappears even after a thorough tub rinse and replacing the detergent brand, pointing to a sensor or dispenser issue.
