Possible Causes

Using non-HE detergent, using too much detergent, blocked pressure hose causing false suds detection, partially clogged drain pump

How to Fix / Troubleshooting

Safety first: Keep children and pets away from overflowing suds. Unplug the unit if it begins to leak.

  • Allow suds to dissipate: The machine may automatically pause to let suds break down. Do not add more detergent.
  • Run rinse and spin: After the cycle ends, run an extra rinse and spin with no detergent to flush remaining suds.
  • Switch to HE detergent: Use only high-efficiency (HE) detergent and follow the dosing instructions for your load size and soil level.
  • Check drain system: Clean the drain pump filter and hoses as described for F02/F21 to ensure proper draining, which helps prevent suds lock.
