Step-by-step fix
Step 1: Confirm the siphon insert is the right part to replace
- Pull the detergent drawer out as far as it will go and release it using the drawer tab or catch if your washer has one.
- Look at the siphon insert in the detergent or softener compartment and check for cracks, warping, a loose fit, broken tabs, or a missing cap section.
- Check for symptoms that point to this part: liquid softener or detergent stays in the compartment, the compartment overflows, or water leaks from the drawer because the insert no longer siphons correctly.
- If the insert just looks dirty, remove it and rinse it first so you do not replace a part that only needed cleaning.
If it works: You have a clear reason to replace the insert instead of chasing a different dispenser problem.
If it doesn’t: If the insert is intact and the drawer still leaks after cleaning, inspect the drawer body and water inlet area for buildup or damage before ordering parts.
Stop if:- The drawer housing itself is cracked or broken.
- You find damaged plastic that prevents the insert from locking in place.
- Water is leaking from somewhere other than the dispenser drawer area.
Step 2: Remove the drawer and old insert
- Set a towel under the drawer area or carry the drawer to a sink because some water or detergent may spill.
- Lift, unclip, or pull the old siphon insert straight up, depending on how it sits in the compartment.
- Do not pry hard against thin plastic walls. If the insert is stuck, wiggle it gently while pulling upward.
- Set the old insert aside so you can compare its shape, tabs, and height to the replacement.
If it works: The old insert is out and the drawer is ready to be cleaned and checked.
If it doesn’t: If the insert will not come out, soak the drawer in warm soapy water for a few minutes to loosen hardened detergent, then try again gently.
Stop if:- The drawer plastic starts cracking or whitening from force.
- A broken piece of the old insert is lodged deep in the drawer and cannot be removed without damaging the drawer.
Step 3: Clean the drawer pocket before installing the new insert
- Wash the drawer compartment with warm water and mild dish soap.
- Use a soft brush to remove detergent sludge, fabric softener film, and mineral buildup from the insert pocket and nearby channels.
- Rinse thoroughly so no loose debris is left behind where the new insert needs to seat.
- Dry the area with a cloth or let it drip dry for a few minutes.
If it works: The insert pocket is clean, open, and ready for the new part to sit flat.
If it doesn’t: If heavy buildup keeps coming back or blocks water flow above the drawer, clean the drawer cavity in the washer as well before reinstalling the drawer.
Stop if:- You find hidden cracks in the drawer compartment that would keep the new insert from sealing or sitting correctly.
Step 4: Match and install the new siphon insert
- Compare the new insert to the old one and make sure the tabs, shape, and depth match.
- Orient the new insert the same way the old one sat in the compartment.
- Press it into place evenly until it sits flat and feels secure. Do not force it if it rocks, binds, or will not seat fully.
- Give it a light tug or wiggle to confirm it is properly engaged and not loose.
If it works: The new insert fits the drawer correctly and sits securely without force.
If it doesn’t: If the new insert does not match the old one closely, stop and verify the washer model before trying another part.
Stop if:- The replacement part is clearly the wrong shape or size.
- The insert cannot lock in because the drawer is damaged.
Step 5: Reinstall the drawer and run a quick test
- Slide the drawer back into the washer rails until it clicks or seats normally.
- Add only a small amount of the correct detergent or softener to the proper compartment for the test.
- Run a rinse, quick wash, or other short cycle that uses the dispenser.
- Watch the drawer area during fill and dispensing if you can do so safely, and check whether the compartment drains as intended instead of overflowing or holding a pool of liquid.
If it works: The drawer dispenses normally and the compartment no longer overflows or leaks from a bad siphon action.
If it doesn’t: If the drawer still leaves liquid behind, remove it again and make sure the insert is fully seated and the drawer channels are completely clean.
Stop if:- Water is pouring from the drawer area during the test.
- The washer shows signs of a separate inlet, valve, or drawer housing problem.
Step 6: Confirm the repair holds in normal use
- Run one full load with your usual detergent amount, avoiding overfilling the drawer.
- Check the dispenser at the end of the cycle for leftover liquid, fresh leaks, or detergent buildup washing out in the wrong way.
- Wipe the drawer dry and make a note to rinse the insert area periodically so residue does not cause the same problem again.
If it works: The washer completes a normal cycle with proper dispensing and no drawer overflow or leak.
If it doesn’t: If the problem returns during normal use, the root cause is likely elsewhere in the dispenser system rather than the insert alone.
Stop if:- The drawer repeatedly overflows even with the correct new insert installed and the drawer cleaned.

FAQ
What does a washer detergent drawer siphon insert do?
It helps the dispenser compartment empty at the right time by creating the siphon action that pulls liquid out of the cup. If it is cracked, missing, warped, or clogged, the compartment may not drain correctly.
Should I clean the insert or replace it?
Clean it first if it is only coated with detergent or softener residue. Replace it if it is damaged, deformed, loose, or still does not siphon properly after cleaning.
Why is there still liquid left in the drawer after I replaced the insert?
The new insert may not be seated fully, the drawer channels may still be clogged, or the problem may be elsewhere in the dispenser system. Remove the drawer and recheck the fit and cleanliness before moving on to deeper diagnosis.
Can I run the washer without the siphon insert?
It is not a good idea. The dispenser may not empty correctly, and you can end up with leftover softener or detergent, overflow, or leaking from the drawer area.
Do I need tools to replace the siphon insert?
Usually no special tools are needed. Most homeowners can do it with just a brush, soap, and a cloth for cleanup.
