Possible Causes of E33 Error code:

• Using too much detergent: 
  • Different water hardness levels require different detergent amounts. Using too much, especially in soft water areas, can create excessive suds.
• Using the wrong type of detergent: 
  • Non-HE detergents are not formulated for high-efficiency machines and can produce more foam.
• Dirty detergent dispenser: 
  • Buildup of detergent residue in the dispenser can contribute to suds formation.
• Soiled or greasy laundry: 
  • Heavily soiled clothes with oil or grease can react with detergent to create more foam.
• Faulty water sensor: 
  • In rare cases, a malfunctioning sensor might misinterpret normal suds levels as excessive foam.

Troubleshooting the E33 error code in Bosch Washing Machine

1. Reduce the detergent amount: 
   • Check your user manual or detergent packaging for the recommended amount based on your water hardness and load size. Start with less and gradually increase if needed.
2. Use HE detergent: 
   • Ensure you're using High-Efficiency (HE) detergent specifically designed for your Bosch washing machine.
3. Clean the detergent dispenser: 
   • Remove the dispenser tray and wash it thoroughly with warm water and mild detergent. Remove any visible residue.
4. Pre-treat heavily soiled laundry: 
   • For greasy or oily clothes, pre-treat the stains with a stain remover before washing.
5. Run a rinse cycle: 
   • If the error persists, try running a rinse cycle without detergent to clear out any remaining suds.
6. Reset the machine: 
   • Unplug the machine for 30 seconds and then plug it back in. This can sometimes clear temporary glitches.
7. Contact Bosch customer service: 
   • If the error continues after trying these steps, it's best to contact Bosch customer service for further assistance. They can help diagnose the issue and recommend the appropriate solution.

Additional Tips:

• Regularly clean the detergent dispenser to prevent residue buildup.
• Choose the appropriate wash cycle for your laundry load and soil level.
• Only use the recommended amount of detergent to avoid suds issues.
• If you suspect a faulty water sensor, contact Bosch customer service for professional diagnosis and repair.
