Whirlpool Washer Leaking from Filter Door? Drain Trap Cap W11568579 – Fix It Fast
A cracked, missing, or improperly seated drain trap cap is one of the most common causes of water leaking from the lower front panel on Whirlpool front-load washers. In most Whirlpool front-loaders, the drain trap cap seals the drain filter access port at the bottom of the machine. When it cracks, strips, or goes missing, water leaks out during every drain cycle — pooling on the floor and potentially triggering error codes. ⚡ Common failure point on Whirlpool WFW-series front-load washers. Part W11568579 is the genuine OEM replacement cap that threads directly onto the drain trap housing and seals the filter port completely.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Washer runs and drains normally — the leak is from the lower front access panel area only
- ✔ The drain filter cap is cracked, stripped, or missing entirely
- ✔ Your washer is a Whirlpool WFW-series front-load model
- ✔ ONLY problem is water leaking from the drain filter access port — not from the door seal or hoses

🔧 Common Symptoms
- Water pooling on the floor in front of the washer after each cycle
- Drain filter cap visibly cracked, chipped, or stripped threads
- Cap missing entirely — open drain port with no seal
- Cap difficult to tighten or won’t seat properly
✔ If these symptoms match, this is the correct replacement part.
✔ In most cases, installing this cap takes under 2 minutes and stops the leak immediately.
📦 Part Details
- Part Number: W11568579
- Type: Washer Drain Trap Cap / Drain Filter Access Cap
- Replaces: W10861225
- Brands: Whirlpool
While the drain filter access panel is open, clean the drain filter/trap itself — a clogged filter is the most common cause of OE/F9E1 drain errors on Whirlpool front-loaders. If the filter is damaged or the drain pump is making noise, inspect the drain pump assembly at the same time. Catching a failing pump now prevents a second service call.
⚙️ Installation
Skill Level: EASY — 2–5 minutes. No tools required. Disconnect power before servicing. Open the lower front access panel and place a towel and shallow pan under the drain port to catch residual water. Unthread the old cap counterclockwise and discard. Thread the new cap clockwise until hand-tight and snug — do not overtighten. Restore power and run a drain cycle to confirm the seal.

💡 Pro Tip
Whirlpool recommends cleaning the drain filter every 3 months on WFW-series front-loaders. Since you’re already replacing the cap, pull the filter all the way out, rinse it under running water, and check for coins, lint, or debris. A clean filter prevents the OE/F9E1 error code, extends pump life, and keeps drain times fast. Takes 5 minutes and saves a service call.
