How to Fix a Washing Machine Not Draining? 7 Most Common Causes and
How to Fix Each One
Washing machine not draining? We cover the 7 most common causes and how to fix each one — plus when repair costs more than replacing your washer.
A washing machine that won’t drain is almost always caused by one of seven fixable problems: a clogged drain hose, a blocked pump filter, a failed drain pump, a faulty lid switch, an overloaded machine, a kinked drain hose, or an unbalanced load. Most of these take under 30 minutes to diagnose at home. If the fix doesn’t hold or your machine is aging a used or scratch-and-dent washer from Appliance Worlds costs 40–70% below retail and comes with a 90-day warranty.
Cause #1
The Short Answer — Yes, But It Depends
Does hot water shrink clothes? Yes, it can. But the real answer depends on two things: the fabric type and the water temperature.
Natural fibers like cotton, wool, and linen shrink much more readily in hot water than synthetic fabrics like polyester or nylon. A 100% cotton t-shirt washed at 140°F (60°C) will shrink noticeably. That same shirt washed at 60°F (15°C) probably won’t.
The key is knowing what’s in your clothes before you wash them
Cause #2
Why Does Hot Water Shrink Clothes? The Science Explained
What Happens to Fabric Fibers in Hot Water
Every piece of clothing is made from fibers twisted into yarn and then woven or knitted into fabric. During manufacturing, those fibers get stretched under tension to form the final shape of the garment.
Hot water releases that tension. When fibers absorb heat and moisture, they relax and contract back toward their natural, shorter state. Once the garment dries, those fibers lock in the new, smaller shape. That’s why your shirt doesn’t “un-shrink” when it cools down.
Cotton fibers, for example, are highly absorbent. When soaked in hot water, their cross-sectional area can swell significantly, and as they dry, the fibers tighten and the fabric pulls inward.
The Role of Agitation — It's Not Just the Heat
Heat alone doesn’t cause all shrinkage. The mechanical action of your washing machine plays a major role too.
As clothes tumble in hot water, fibers rub against each other. This is especially damaging for wool, which has a scaly surface. The scales open in heat and interlock with neighboring fibers — a process called felting. Once wool felts, there’s no going back.
This is why front-load washers with gentler drum action tend to cause less shrinkage than older top-load agitator models. The right washer genuinely makes a difference.
Cause #3
Which Fabrics Shrink the Most in Hot Water?
Fabric | Shrink Risk in Hot Water | Notes |
Cotton | High | Can shrink 3–5% in a single hot wash |
Wool | Very High | Prone to felting — irreversible damage |
Linen | High | Shrinks and wrinkles badly in heat |
Silk | High | Loses shape and sheen in hot water |
Rayon | High | Very sensitive — even warm water causes issues |
Polyester | Low | Resistant to shrinkage, but high heat can warp it |
Nylon | Low | Handles heat better, but avoid very hot settings |
Cotton/Poly Blend | Medium | Less shrinkage than 100% cotton, but not shrink-proof |
Cause #4
Hot Water vs. High-Heat Dryer — Which Shrinks More?
This is one of the most common questions — and the answer surprises most people.
Your dryer causes more shrinkage than your washer. Heat + tumbling + fast evaporation of moisture all combine to tighten fibers faster and more severely than soaking in hot water alone. According to GE Appliances, an estimated 75–90% of the energy your washer uses goes just to heating water — and that heat is doing real work on your fabrics.
Washing in cold water and then drying on high heat still shrinks clothes. If you want to protect your wardrobe, you need to manage both — the wash temperature and the dryer setting.

Cause #6
What Temperature Is "Hot" Enough to Shrink Clothes?
Below 85°F / 30°C
Cold wash — minimal shrinkage risk for most fabrics
85–105°F / 30–40°C
Warm wash — safe for most cotton blends; natural fibers may shrink slightly over time
Above 120°F / 50°C
Hot wash — significant shrinkage risk for cotton, wool, linen & silk
140°F / 60°C & above
Very hot — for towels & bedding only, not everyday clothing
What If Your Washer Is the Problem?
Older washing machines — especially top-loaders with a central agitator — are rough on fabric. The agitator physically beats clothing against itself during the wash cycle, which causes fiber friction, pilling, and shrinkage even at lower temperatures.
If your washer defaults to hot water or doesn’t give you temperature control, your clothes are at risk every single wash.
At Appliance Worlds RVA, we carry a wide range of washers and dryers — including certified used and scratch & dent units from trusted brands like Whirlpool, GE, and Frigidaire — all at a fraction of retail price. Every unit is technician-tested before it leaves our Highland Springs store.

❓ Frequently Asked Questions
Does hot water shrink all clothes?
No. Synthetic fabrics like polyester and nylon have low shrink risk in hot water. Natural fibers — cotton, wool, linen, silk — are most vulnerable. Always check your garment’s care label before choosing a wash temperature.
How much does cotton shrink in hot water?
Cotton can shrink anywhere from 1% to 5% in a single hot wash, depending on whether it has been pre-shrunk and how high the water temperature is. Pre-shrunk cotton (often labeled “preshrunk”) has already been treated and is less likely to shrink further.
Does warm water shrink clothes too?
Warm water (85–105°F) can cause gradual shrinkage in natural fiber garments over multiple washes, but it’s far less aggressive than hot water. For most everyday fabrics, warm water is a safe middle ground.
Can I unshrink clothes that shrank in hot water?
You can sometimes restore cotton and blended fabrics by soaking them in lukewarm water with conditioner and gently stretching them back into shape. Wool that has felted cannot be restored. Prevention is always the better approach.
What washer setting is safest for clothes?
The cold or delicate cycle is safest for most garments. Cold water minimizes shrinkage, and the gentle cycle reduces physical abrasion on fabric fibers. For everyday loads, a warm wash (not hot) is a reasonable option for cotton blends and moderately soiled items.
