How to Install Tub Bolt W10175939 in a Whirlpool Washer
Quick answer: Unplug the washer and shut off both water valves, open the front panel to reach the underside of the outer tub, back out the old tub bolt, clean the seat, fit the new W10175939 bolt with its seal and tighten it snug, then run a short fill and spin to confirm no drips.
Tub bolt W10175939 is one of the small fasteners that hold the outer tub of a Whirlpool-built top-load washer to its mounting point at the base of the machine. It does more than clamp metal: the bolt passes through a sealed hole in the outer tub, so a corroded, stripped or loose bolt is a common source of a slow drip that shows up as a puddle under the washer after every wash.
This guide walks through swapping the bolt on the classic top-load and stacked laundry-center designs this part is listed for, including popular models such as LSE9900AFW, LAT8206AAE and LSE7806BCE. Our fitment data shows it fits hundreds of Whirlpool family washers, so always confirm your model number on the rating plate inside the lid or on the rear panel before ordering. The job is mostly access work: once the front panel is off, the bolt itself takes only a few minutes.

- Unplug the washer before you open any panel; the motor and controls stay live even when the machine is idle.
- Close both the hot and cold supply valves and drain any standing water from the tub so it cannot spill on you or on electrical parts.
- Wear gloves: the cabinet edges and the underside of the outer tub are sharp, and old bolts may have rust flakes.
- Never lean the washer on the control console; if you must tip it, tip it toward the back and have a second person steady it.
Tools and Parts You Need
- Replacement tub bolt W10175939 (one per mounting point you are servicing)
- Socket set or nut driver sized to the bolt head
- Putty knife to release the front panel spring clips
- Flashlight or headlamp
- Shop towels and a small tray for water that drains from the tub
- Work gloves
- Wire brush or emery cloth for cleaning the bolt seat
Step-by-Step Installation
- Kill power and water Pull the plug and shut off both supply valves. Run a drain cycle first if the tub still holds water, or bail it out and dry the bottom with towels.
- Open the front panel On these top-load designs the front panel is held by two spring clips at the top edge. Slide a putty knife in about two inches from each corner, press the clip and tilt the panel out, then lift it off its bottom hooks.
- Locate the tub bolts Look under the outer tub with a flashlight. The tub bolts sit where the tub bottom meets the mounting base; there is usually more than one, spaced evenly around the mount. Identify which one is leaking or damaged by looking for rust streaks or mineral trails.
- Remove the old bolt Fit the correct socket and back the bolt out slowly. If it spins without loosening, hold the mount from below with a second wrench. Catch any water that follows the bolt out of the hole.
- Clean the seat Brush rust and old sealant off the tub surface and the threads in the base. A clean, flat seat is what lets the seal on the new bolt do its job.
- Install W10175939 Thread the new bolt in by hand first so you know it is not cross-threaded, then tighten with the socket until it is snug and the seal is compressed. Do not overtighten; the tub is thin metal and can distort.
- Check the neighbors While the panel is off, check the other tub bolts for the same corrosion. If one has failed, the rest are often close behind and it is cheaper to replace them now than to reopen the machine later.
- Reassemble and leak test Hook the front panel on its bottom tabs, snap the top clips in, restore water and power, and run a short cycle with the lid closed. Watch the floor at the front and sides for any moisture.
Fit Checks Before You Call the Job Done
- The new bolt threads in smoothly by hand for the first few turns; resistance means the threads are misaligned.
- The bolt head seats flat against the tub surface with the seal compressed evenly all the way around.
- No water beads at the bolt head during a full fill and agitate.
- The outer tub does not rock or knock when you push it gently by hand after tightening.
- Model on the rating plate appears in the fitment list, for example LSE9900AFW or LAT9606AAM.
Common Mistakes to Avoid
Skipping the drain Opening the tub bolt with water still in the outer tub floods the base and can soak the motor. Always empty the tub first.
Reusing a rusty bolt Cleaning a corroded bolt and putting it back rarely stops the leak. The seal surface is already pitted; use the new part.
Overtightening Cranking the bolt down crushes the seal and can crack the tub flange. Snug plus a quarter turn is the rule of thumb.
Replacing only one bolt Tub bolts age together. If the panel is already off, inspect every one and replace any with rust or stripped threads.
Troubleshooting After Installation
Still dripping after the swap Pull the panel again and confirm the leak is at the bolt and not at a hose, the tub seal or the outer tub seam. Re-seat the bolt on a cleaner surface if the seal shows a gap.
Bolt will not tighten The threads in the base are stripped. Do not force it; a thread repair insert or a new base mount is needed.
New knocking during spin A tub bolt is loose or the tub is sitting unevenly on its mount. Tighten all bolts evenly and confirm the tub sits level.
Care Tips After the Repair
- Check under the washer for moisture every few months; a fresh drip caught early saves the floor and the bearings.
- Use the right amount of detergent. Oversudsing pushes foam into the outer tub area and speeds up corrosion of steel fasteners.
- Keep the washer level so the tub does not hammer its mounts on every spin.

Frequently Asked Questions
How many tub bolts does my washer use?
Most of these top-load designs use several bolts spaced around the tub mount. W10175939 is sold individually, so count what your machine has and order one per bolt you plan to replace.
Do I need a new seal or washer with the bolt?
The bolt is designed to seal against the tub. If your old bolt had a separate rubber washer under it and it is torn, replace that as well; a damaged washer will keep leaking around a new bolt.
Can I use a hardware store bolt instead?
A generic bolt will not have the correct thread, head shape or corrosion protection for a wet environment. The savings are small and the risk of a repeat leak is high.
Is this the same on stacked laundry centers such as LSE9900AFW?
Yes. The washer section of these stacked units uses the same tub mount design. Access is through the lower front panel, and the dryer above does not need to be removed.
