🔎 On Amazon →The Fix — Free Checks First, Then the Part
Work top-down: the free checks before you spend a dime, and test to confirm the part is actually bad before you buy. When it is a part, you get both options — the genuine OEM part sourced through us and shipped to your door, or a budget aftermarket part on Amazon. Your call.
No part — less HE detergent + rinse
Run a rinse/spin to clear the foam, then use only 1–2 teaspoons of HE detergent. Non-HE soap oversuds badly in HE machines.

A clogged pump filter/coin trap can trap suds and re-trigger SD. Clean it (towel down).

Safe to Try · Know the Risk · Call a Pro
General guidance, not professional advice. Always unplug the appliance (or shut off the gas/water) before you check anything. If it feels beyond you, that's exactly when to get a pro.
✅ Safe to try yourself
- Run a rinse/spin cycle to clear the suds.
- Switch to HE detergent and use only 1–2 teaspoons.
- Clean the drain-pump filter if SD keeps returning.
⚠️ Doable — know the risk
- None — a detergent/cleaning fix, no parts.
🛑 Call a pro — don't touch this
- Rarely needed — only if SD persists with correct HE detergent and a clean filter.
