Why Won’t My Washing Machine Spin? Understanding Spin Faults and Unbalanced Loads

Have you ever loaded your washing machine, pressed start, and then returned an hour later to find it’s still going – or displaying a “spin fault” error? Perhaps your machine seems to take forever to finish the spin cycle, stopping and starting repeatedly as it tries to redistribute the load?

If your washing machine won’t spin properly, takes ages to complete a cycle, or displays spin fault errors, you’re likely dealing with an unbalanced load issue. This is one of the most common problems we see with modern washing machines here in Bath, and it’s not always the machine’s fault.

Before you call an engineer, here’s a quick check: Open the door and look at what’s in the drum. Is it a single jumper? Tangled bedding all clumped to one side? A lone bath mat? If so, you’ve found your problem – it’s an unbalanced load, not a mechanical fault. Simply redistribute the items, add a few more pieces if the load is too small, and try again.

Let’s explore why this happens, how to prevent it, and when it might signal a more serious problem that needs professional attention.

Why Modern Washing Machines Are So Sensitive to Unbalanced Loads

Modern front-loading washing machines are engineering marvels, but they’re also much more sensitive than the robust machines of decades past. Here’s why:

The Technology Behind the Stoppage

Your washing machine isn’t just being difficult when it stops mid-cycle. It’s actually protecting itself and your kitchen from damage. Here’s how it works:

Sophisticated Sensors: Modern machines use advanced sensors that constantly monitor the drum’s rotation and vibration patterns. When the load becomes unevenly distributed, these sensors detect irregular movement almost immediately.

Suspension System: The drum sits on a suspension system made up of springs and shock absorbers. When laundry clumps to one side during the spin cycle, it creates an imbalanced weight distribution. This puts enormous strain on these components, causing excessive vibration.

Protective Design: When the control board detects this irregular movement, it stops the spin cycle or displays a “spin fault” error. This isn’t a malfunction – it’s a safety feature designed to protect both the internal mechanics of your machine and your surrounding cabinetry from damage. An unbalanced drum spinning at 1400 RPM can cause significant damage if left unchecked.

The machine will typically attempt to redistribute the load several times, which is why your cycle seems to take forever. You might hear the drum slowly rotating back and forth as it tries to even out the load. If it can’t achieve balance after multiple attempts, it will either stop completely with an error, or finish the cycle without spinning properly – leaving your clothes soaking wet.

Higher Spin Speeds: Today’s machines spin faster than ever (typically 1200-1600 RPM compared to 800-1000 RPM in older models). While this means better water extraction and faster drying times, it also means any imbalance is amplified dramatically.

Without this protective mechanism, an unbalanced load could damage the drum bearings, snap suspension springs, or even cause your machine to “walk” across the floor and damage your kitchen units.

The Large Drum Dilemma: When Bigger Isn’t Better

One of the biggest contributors to unbalanced load problems is the trend toward larger capacity washing machines. While a 10kg or 12kg drum might seem appealing, it’s not suitable for everyone.

The Problem with Big Drums and Small Loads

Here’s what many people don’t realize when buying a new washing machine: the larger the drum capacity, the more prone it is to unbalanced load issues when not filled properly.

A large capacity drum needs a certain amount of laundry to create the balanced distribution needed for the spin cycle. When you put just a few items in a massive drum, they have too much space to move around. During the spin cycle, these items inevitably clump together on one side, creating an imbalance.

Matching Machine Size to Your Household

Large capacity machines (9kg-12kg) are ideal for:

• Large families doing multiple loads daily
• Households regularly washing bulky items like duvets and large towels
• People who accumulate significant amounts of laundry between washes

NOT suitable for:

• Single people or couples doing small, frequent loads
• Anyone who prefers to wash items as soon as they’re dirty
• Households with limited laundry volume

If you’re a single person or couple who likes to do small loads regularly, you’re much better off with a 6kg-8kg machine. You’ll have far fewer issues with unbalanced loads and your machine will perform more efficiently.

When buying a new washing machine, it’s worth checking independent reviews and ratings from Which? to find a model that suits your household size and needs.

The Golden Rule for Loading Your Washing Machine

After years of repairing washing machines across Bath, I’ve developed a simple rule that prevents most unbalanced load problems:

Keep your drum between half and two-thirds full – never more, never less.

Why This Works

Too Empty (less than half full): Items have too much room to move and will clump together during the spin cycle, especially in larger drums.

Too Full (more than two-thirds): Overloading prevents proper water circulation and doesn’t allow the drum to redistribute the load effectively. It also puts strain on the motor and bearings.

Just Right (half to two-thirds): Laundry has enough room to move and agitate properly during the wash, but not so much space that it can form an unbalanced clump during the spin.

How to Judge the Right Amount

A good visual test: when you look into your drum after loading, you should be able to fit your hand vertically between the top of the laundry and the top of the drum with your fingers pointing upward. If you can’t fit your hand, it’s too full. If there’s a huge gap, add more items.

Loading Techniques to Prevent Unbalanced Loads

Beyond the quantity of laundry, HOW you load your machine matters just as much:

Mix Item Sizes

Don’t wash all similar items together. For example, washing only small items (like socks and underwear) or only large items (like bath towels) increases the chance of imbalance. Mix small and large items to help the load distribute more evenly.

Distribute Manually

Take an extra 30 seconds to distribute items evenly around the drum rather than dumping everything in one clump. This simple habit can save you from multiple interrupted cycles.

Heavy Items Need Attention

Single heavy items like bath mats, thick towels, or waterlogged jeans are notorious for causing problems. If you must wash these items, always include a few lighter items to help balance the load.

Use the Right Programs

Many modern washing machines include specialist programs for bulky items. If your machine has a duvet or bedding program, use it! These programs are specifically designed to handle large, heavy items that are prone to causing imbalances. They typically:

• Use different drum rotation patterns
• Allow for longer redistribution attempts
• Adjust spin speeds for heavier loads

When It’s Not Just a Loading Issue: Mechanical Problems

Sometimes, no matter how carefully you load your machine, it still won’t spin properly or displays persistent spin fault errors. This could indicate a mechanical fault rather than a loading problem.

Warning Signs of Mechanical Issues

Your machine might need professional repair if:

• It displays spin fault errors on EVERY load, regardless of how you load it
• The cycle takes hours to complete as it repeatedly tries to spin
• Clothes come out soaking wet because the spin never completes
• There’s standing water left in the drum after the cycle ends (check the filter first!)
• You hear loud banging or clunking during attempted spins
• The drum feels loose or wobbles when you manually rotate it
• The machine has started “walking” across the floor during cycles
• You notice water leaking during spin attempts
• You can smell burning during the cycle (possible motor brush issue)

Common Mechanical Causes

Worn Shock Absorbers: These dampen the drum’s movement during the spin cycle. When they wear out, even a balanced load can cause excessive shaking.

Damaged Suspension Springs: These support the drum. If one breaks or weakens, the drum can’t maintain proper balance.

Faulty Bearings: Worn drum bearings create play in the drum, making it impossible to maintain balance even with a perfect load.

Worn Motor Brushes: Carbon brushes in the motor wear down over time. When they get too low, the motor can’t generate enough power to spin the drum, especially under load. This often presents as a spin fault or the drum simply not spinning at all, even though the wash cycle completed normally.

Blocked Filter: A blocked pump filter prevents water from draining properly. If water can’t drain, the machine won’t attempt to spin (it’s a safety feature). This is one of the most common causes of “won’t spin” issues, and it’s often accompanied by standing water in the drum. The good news? It’s usually an easy fix – cleaning the filter takes just a few minutes.

Unlevel Installation: If your machine isn’t level, the drum can’t spin on a true axis, causing persistent balance issues.

The Bath Context: Hard Water and Your Machine

Living in the Bath area, there’s another factor that can contribute to washing machine problems: our notoriously hard water. While hard water doesn’t directly cause unbalanced loads, limescale buildup can affect your machine’s performance over time, making it less effective at redistributing loads.

Regular maintenance and using the right detergent for hard water areas can help keep your machine running smoothly. You can read more about hard water’s effects on appliances in our previous post.
