What Does Error SUD-LOC Mean?
The SUD-LOC error in Fisher & Paykel washing machines indicates a suds lock condition caused by excessive foam buildup. This can lead to the machine stalling during the final drain or spin cycle, as it misdetects the level of suds. To resolve this, allow the machine to sit for about 20 minutes to let the suds dissipate, then run a rinse or extra spin cycle. Ensure the drain hose is free from kinks and clogs to facilitate proper drainage.
Common Symptoms:
- Cycle stalls during or before final drain/spin
- Machine displays SUD-LOC and may pause for extended period
Possible Causes
- Slow or impeded drain leading to mis‑detection of suds (medium)
- Actual suds buildup from detergent (medium)
