You walk into the laundry room and see your washer paused with Sd or 5d on the display. It looks like a bubble bath inside. This code stands for “Suds Detected”. The washer has sensed “drag” on the basket caused by a massive wall of foam and has stopped spinning to prevent damage.
The Fix: This is rarely a broken part. It is usually a “User Error” (Too much soap) or a clogged drain filter. The fix involves patience, a little chemistry (Vinegar), and cleaning the “Coin Trap”.
🎥 The Repair Video
If waiting doesn’t clear the code, you need to manually drain the soapy water and clean the filter. Watch this guide by Scott The Fix-It Guy to see how to access the Drain Pump Filter (Coin Trap) without flooding your floor.
🛒 Parts & Tools Checklist
You likely don’t need new parts, just cleaning supplies. But if the pump is dead, I’ve listed it below.
-
The “Suds Killer” (Vinegar/Affresh):
👉 Check Price for Affresh Washer Cleaner
(Use this AFTER the repair to strip soap residue.) -
The “Hardware Fix” (Drain Pump):
Check Price for OEM Drain Pump (W10536347)
(Only if the impeller is broken or stuck.) -
Essential Tool (Shop Vac):
Wet/Dry Shop Vac (To suck out the foam)
⏳ Step 1: The “Patience Fix” (Let It Ride)
Don’t panic and unplug it yet.
When the computer flashes Sd, it is running a special “Suds Reduction Routine”. It adds cold water and pauses the spin to pop the bubbles.
- What to do: Leave it alone for 2 hours.
- Did it clear? If the cycle finishes, run a “Clean Washer” cycle immediately with NO detergent to flush the lines.
- Stuck? If it’s still stuck after 2 hours, proceed to Step 2.
⚗️ Step 2: The “Chemistry Hack” (Vinegar)
Foam is stubborn. If the washer is full of bubbles, pouring more water won’t help.
- Add Vinegar: Pour 1 cup of Distilled White Vinegar or a capful of Liquid Fabric Softener into the detergent dispenser.
- Why? Both act as a “de-foamer” to collapse the bubble structure instantly.
- Force a Drain: Press “Power”, then select “Drain & Spin”. The vinegar will mix with the suds and help the pump clear them.
🧹 Step 3: The Manual Clean (Coin Trap)
If the pump creates a humming noise but water won’t leave, the soap scum has likely clogged the filter.
- Remove the Toe Panel: As shown in the video, remove the bottom panel screws (usually T-20).
- Prepare for a Flood: Put a shallow baking sheet and towels under the pump.
- Open the Trap: Slowly unscrew the large round filter cap. Thick, slimy soap goo will likely pour out, along with lint or coins.
- Clean it Out: Rinse the filter. Stick your finger in the housing to check for lost socks.
- Reassemble: Screw the cap back on tight (hand tight only!).
⚠️ Step 4: The Top Load Exception (Cabrio Owners)
If you have a Top Load Whirlpool (Cabrio/Bravos) and you get Sd, but you didn’t use too much soap:
- The Issue: Your Basket Hub (the plastic gear under the agitator) might be stripped.
- Why? When the hub strips, the basket slips. The computer feels this “drag” and confuses it with suds “drag”.
- The Test: If your washer makes a “grinding” noise during spin, check the Basket Hub, not the soap.
🛡️ Step 5: Prevention
Sd is 100% preventable.
- Use HE Detergent Only: Look for the “High Efficiency” logo.
- Use Less: You only need 2 tablespoons of detergent for a normal load. Modern soap is highly concentrated.
- Clean Monthly: Use an Affresh tablet once a month to eat away the soap scum buildup in the pump.
