What this code means
bE commonly points to excessive suds from the wrong detergent or a dishwasher that is not level. On some models additional spray-system or pump conditions may contribute.
Most likely causes
- Hand dishwashing liquid or another high-foaming product was used
- Food residue with heavy foam entered the dishwasher
- The cabinet is not level from side to side or front to back
- A filter, spray arm, water guide or vario system is obstructed or damaged
Safe checks for the owner
- Stop using hand dish soap and use only detergent labeled for automatic dishwashers.
- Check for visible foam and allow the machine to drain before attempting another normal cycle.
- Verify that the dishwasher is firmly mounted and level.
Estimated U.S. repair cost
$120–$320, depending on model, access, parts availability and local labor.
