Possible Causes of Suds Lock Error (E SudS or Er, SL):

• Excessive Suds: The washer's sensors detect more suds than anticipated, potentially hindering the cleaning process or causing the washer to overflow.

Potential Causes:

• Improper Detergent: Using the wrong type of detergent, using too much detergent, or using a detergent not formulated for high-efficiency (HE) washers (if your Speed Queen model is HE) can all contribute to excessive suds.
• Dirty or Clogged Drain Filter: A clogged drain filter can prevent proper water drainage, leading to a higher concentration of suds in the wash water.
• Faulty Suds Sensor (Less Likely): In rare cases, a malfunctioning suds sensor might be misinterpreting the suds level.

Troubleshooting Steps

1. Unplug the Washer: Before attempting any troubleshooting, ensure the washer is unplugged for safety reasons.
2. Check the Manual: Consult your Speed Queen washer's user manual for specific instructions on locating and cleaning the drain filter.
3. Clean the Drain Filter: Remove and clean the drain filter according to the manual's instructions. This can help improve water drainage and reduce suds buildup.
4. Reduce Suds: If the filter is clean and the problem persists, you might need to reduce the amount of suds. Here's how:
   • Open the Lid: Carefully open the washer lid (if safe to do so) and scoop out some of the excess suds with a cup or other container.
   • Adjust Detergent Amount: In future washes, use less detergent than the recommended amount. Start with half the recommended dose and see if the suds level is under control. You can gradually increase the amount if necessary.
   • Use HE Detergent (for HE Washers): If your Speed Queen washer is a high-efficiency model, ensure you're using a detergent specifically formulated for HE washers. These detergents produce lower suds levels.

If the Problem Persists:

• Contact Speed Queen Support: If cleaning the filter and reducing detergent usage don't resolve the issue, contacting Speed Queen's customer support is recommended: They can provide further guidance and determine if the issue requires a qualified technician's expertise.
• Qualified Technician (Less Likely): In rare cases, a faulty suds sensor might be the culprit. A qualified technician can diagnose this issue and recommend a replacement if necessary. However, this is less likely compared to the other causes mentioned above.

Safety Considerations:

• Avoid Excessive Force: Don't force the washer lid open if it's locked during the cycle. Wait for the cycle to finish or consult the manual's instructions for safely interrupting the cycle.
• Limited User Repair: While cleaning the drain filter is a user-friendly task, avoid disassembling components or handling electrical wiring unless your manual provides specific instructions and you are comfortable doing so.

By following these steps and prioritizing safety, you should be able to resolve the E SudS or Er, SL error on your Speed Queen washer. If the problem persists after trying the recommended solutions, consult Speed Queen's support or consider seeking help from a qualified technician.
