If your Maytag MHW5630HC3 washer is showing an SD error, don’t panic — you’re not alone! At Atlanta City Appliance Repair, we frequently help customers with this issue across Atlanta, Brookhaven, Sandy Springs, Roswell, and Alpharetta.
Let’s break it down clearly for you:
What Does “Washer Showing SD Error” Mean?
The SD (or SUD) error code means your washer detects too many suds inside the drum.
Excess suds make it difficult for the machine to rinse and spin properly, sometimes causing the cycle to stop.
Why Is My Washer Showing SD Error? 
From our experience servicing hundreds of washers, here are the most common causes:
- ❌ Using too much detergent
- ❌ Using the wrong (non-HE) detergent
- ❌ Residual suds — Even after switching back to the correct detergent, suds can stay trapped for 2–3 loads.
- ❌ Clogged drain pump or filter
- ❌ Rare internal issues (such as a faulty drain pump or control board)
Our Field Advice at Atlanta City Appliance Repair
When your washer shows an SD error, here’s what we recommend:
1. Flush Out the Washer
- Run 2–3 empty wash cycles with no detergent to clear out any remaining suds.
2. Clean with Vinegar
- Run a cleaning cycle using white vinegar to break down detergent buildup.
3. Use the Right Detergent
- Always use HE (High-Efficiency) detergent in the correct amount.
- Too much detergent is one of the most common causes of the SD error!
4. Check the Drain System
- Look for any blockages in the drain pump or drain filter that could prevent the washer from draining properly.
When to Call a Professional
If after flushing and cleaning you still see the washer showing SD error, there might be a deeper issue such as:
- Faulty drain pump
- Malfunctioning control board
These cases are rare, but they do happen — and our expert technicians are ready to help!
