How to Install Outer Tub 3361596 in a Whirlpool Washer
Before You Replace the Outer Tub
A washer outer tub is a structural part. It supports the wash basket area and helps contain water during the cycle. Because it sits deep inside the cabinet, you need to remove parts in a clear order.
Do not start this repair if you only have ten spare minutes. Set aside 30 to 60 minutes, plus extra time if parts are stuck or the washer has heavy buildup. The install difficulty is medium because the work involves access, lifting, alignment, and reassembly.
You should also decide if the washer is worth the repair. If the machine has several failures at once, inspect those first. A bad lid switch, drain issue, belt issue, or motor issue can also make a washer not work properly. The outer tub should be replaced when inspection points back to the tub itself.
Check the official Whirlpool support resources when you need model-specific diagrams or manuals. Whirlpool provides a Product Help Library and Service & Support manual lookup. Use those resources to confirm safe access steps for your washer style.
Confirm the Right Part and Model
Match the washer model before you remove the cabinet. A part that looks close can still be wrong. Tub shape, mounting points, seals, and related hardware can vary by model.
Use these supplied compatible models only:
| Brand | Appliance | Part Type | OEM Number | Supplied Compatible Models |
|---|---|---|---|---|
| Whirlpool | Washer | Outer Tub | 3361596 | 110.20702990, 110.20722990, 110.26912691, 110.28803890, 110.28892790 |
Find the model tag on the washer. It may sit under the lid, near the opening, behind the console area, or on the rear panel. Read the full number. Do not stop after the first three digits.
Write the model number on paper. Then compare it to the compatible model list above. If your number is not listed here, pause and verify fit through a trusted parts source before buying or installing the tub.
You should also compare the old outer tub to the replacement before final assembly. Look at the mounting areas, hose openings, and general shape. Do not force parts together when something clearly does not line up.
Signs the Outer Tub May Be the Problem
The supplied symptom is “washer not working properly.” That can sound broad, so narrow it down before you start. The outer tub sits at the center of the wash system. When it has a crack, bad mounting area, or damaged surface, the washer can show several related signs.
You may notice water under the washer during fill or wash. You may also see leaks that appear only when the basket moves. A tub issue can hide until the washer fills high enough or starts agitation.
Noise can also point toward tub trouble. If the basket rubs, scrapes, or shifts in a strange way, inspect the tub area. Do not assume every noise means the outer tub failed. Worn drive parts can also make noise.
Poor cycle action can happen when the tub assembly cannot sit correctly. The washer may shake, stop, or fail to move through the cycle as expected. A loose or damaged support area can make the machine feel unstable.
Inspect before you replace. Remove enough parts to view the tub clearly. Look for cracks, damaged mounting areas, worn spots, or signs of water tracks. Water trails often leave mineral marks, dirt lines, or rust stains on nearby parts.
Safety First
Unplug the washer before you touch internal parts. Do not rely on the control knob or cycle setting. Power must be off at the cord.
Turn off the water supply valves. Then disconnect the fill hoses if you need rear or cabinet access. Keep a towel nearby because hoses can hold water after the valves are closed.
Wear gloves. Cabinet edges, clips, and brackets can cut your hands. Eye protection also helps when you work around springs, clips, and old residue.
Move the washer only as much as needed. Washers can be heavy and awkward. Ask for help if the machine must be pulled out from a tight space.
Keep children and pets away from the work area. Small clips, screws, and tools can roll under the washer. They can also create a tripping hazard.
Take photos before removing wires, hoses, or brackets. A photo saves time when reassembly starts. It also helps you avoid crossed connections.
Tools and Supplies You May Need
Use basic hand tools unless your washer manual calls for a special tool. Do not use force as a repair method. If a part will not move, stop and find what still holds it.
Common tools may include:
- Phillips screwdriver
- Flathead screwdriver
- Nut driver set
- Pliers
- Adjustable wrench
- Towels
- Work gloves
- Small container for screws and clips
- Phone camera for reference photos
- Flashlight
You may also need a putty knife for spring clips on some washer cabinet styles. Use care with painted surfaces. Slide tools in gently and avoid bending panels.
Do not mix screws from different areas. Place them in separate groups. Label each group if needed. Reassembly goes faster when every fastener returns to the right place.
How to Install Outer Tub 3361596: Step-by-Step
Common Mistakes That Cause Leaks or Noise
Most problems after this repair come from rushed reassembly. The outer tub must sit in the right position. Hoses, clamps, and supports must return to their correct spots.
A loose hose clamp can create a slow leak. It may not show during the first fill. It may appear later when the washer agitates or drains.
A twisted hose can also leak. It can pull against the port as the tub moves. Check that each hose has a natural path.
A misseated cabinet can cause rattles. The washer shell may touch moving parts or vibrate against the base. Reset the cabinet if it does not sit square.
A loose support can cause banging. Check springs, brackets, and mounting areas before closing the machine. If the tub leans, something is not seated correctly.
Do not skip the hand-spin check. It catches rubbing before power returns to the washer. It also helps you find a basket or tub part that sits off-center.
When You Should Stop and Get Help
Stop if you see burned wiring, melted connectors, or damaged electrical parts. The outer tub repair does not fix electrical damage.
Stop if the washer frame is cracked or badly rusted. A new tub cannot correct a weak frame.
Stop if the basket will not release and you are about to force it. Stuck parts need patience, cleaner, or model-specific service steps.
Stop if you cannot confirm part fit. Installing the wrong outer tub wastes time and can damage related parts.
Stop if water leaks from several areas after reassembly. You may have more than one failed part. Diagnose the leak path before running more cycles.
Original Pitfall Ranking for This Repair
| Rank | Pitfall | Why It Matters | Best Move |
|---|---|---|---|
| 1 | Wrong model match | The tub may not mount or seal right | Confirm the full model number first |
| 2 | Loose hose clamp | It causes leaks after fill or agitation | Seat hoses fully and clamp at the seal area |
| 3 | Misaligned tub | It causes rubbing, noise, or poor spin | Start fasteners loose, then tighten evenly |
| 4 | Mixed hardware | Screws may not hold the right part | Group fasteners by repair stage |
| 5 | Skipped test cycle | Small leaks go unnoticed | Run fill, wash, drain, and spin checks |
Use this table before you close the washer. It gives you a quick quality check. The highest-risk mistakes are fit, seal, and alignment issues.
Repair Time and Difficulty
Plan on 30 to 60 minutes for this repair. Add time if the washer sits in a tight laundry closet. Add more time if old hoses stick or the cabinet clips fight you.
The difficulty is medium. You do not need advanced electronics work for the basic tub swap. You do need patience and careful part handling.
A first-time repair may take longer than the estimate. That is normal. Photos, labels, and organized screws reduce mistakes.
Do not rush the final test. A washer can look fixed while still leaking under load. Let it fill enough to prove the tub and hoses are sealed.
How to Keep the Washer Area Clean During Repair
Water and lint can make this job messy. Start with towels under the front and rear of the washer. Keep a small container nearby for wet clamps or hoses.
Wipe spills right away. A wet floor can make the washer slide when you pull on parts. It also makes tools harder to handle.
Clean the cabinet base while the washer is open. Remove old detergent sludge and loose debris. Clean parts help you spot fresh leaks during testing.
Do not spray cleaner into switches, wires, or the motor area. Apply cleaner to a rag instead. Then wipe the surface by hand.
What to Check After the First Load
Run one light load after the test cycle. Stay near the washer. Watch the floor during fill, wash, drain, and spin.
Check the area behind the washer after the load. Hose fittings can seep slowly. A dry paper towel can help you spot moisture.
Listen during spin. New banging or scraping means something may be loose or misaligned. Unplug the washer before you inspect it.
Smell for hot or electrical odors. Stop the washer if you notice a sharp burning smell. That points to a separate issue, not normal tub replacement.
Look under the washer after the cycle ends. A small drip still matters. Find the source before using the washer again.

Final Checklist Before You Push the Washer Back
Use this checklist before you return the washer to its normal spot.
- The washer is unplugged during inspection.
- The outer tub matches the supplied part and model information.
- All mounting points are seated.
- Hoses sit fully on their ports.
- Clamps are back in sealing position.
- Supports and brackets are reconnected.
- The basket turns without hard rubbing.
- The cabinet sits square on the base.
- The console and wire harnesses are secure.
- Water valves are open with no hose drips.
- The test cycle shows no leaks.
- The washer drains and spins without new noise.
Do not skip the last floor check. Water can travel along a frame rail before it drops. Look at the front, sides, and rear.
If everything stays dry, push the washer back into place. Keep hoses from kinking behind the machine. Leave enough room so hoses curve naturally.
