Washer-dryer combo displays "Sd" or "SUD" and may pause or extend the cycle; excessive suds visible.

Safety first: Do not open the door mid-spin; wait for the drum to stop.

Step-by-step checks:

• 1. Let cycle finish: The machine will attempt to clear suds by adding rinses. Allow it to complete.
• 2. Use HE detergent: Only use high-efficiency (HE) detergent and follow the dosage on the label, reducing the amount for soft water or small loads.
• 3. Run rinse and spin: If suds remain, run an extra rinse and spin with no detergent.
• 4. Check drain and pressure system: If Sd appears frequently even with correct detergent use, inspect the drain pump, hose, and pressure hose for partial blockages as described under F21 and F10.
