The Most Common Causes of a Washing Machine Not Spinning
If your washing machine will not spin — or spins weakly and leaves clothes very wet — there are several possible causes ranging from simple user fixes to faults that need an engineer. Here is what to check, in order of likelihood:
1. Overloaded or Imbalanced Drum
The most common reason for a machine failing to spin (especially if it flashes an error code or buzzes) is an unbalanced load. A single heavy item like a duvet or towel can prevent the machine from reaching spin speed. Try redistributing the load and running the spin cycle again. If you regularly experience this, check you are not overloading — most 8kg machines should not be filled above 80–85% capacity.
2. Lid or Door Not Fully Closed / Door Lock Fault
All modern washing machines require the door interlock to be fully engaged before the drum will spin. Check the door is fully closed with a click. If the door lock mechanism has failed, the machine cannot spin even if the door is closed — you may hear a buzzing or clicking from the lock. Door lock replacement costs £75–£130.
3. Drainage Issue
A washing machine will not spin if it has not drained properly first. Check the filter (usually at the bottom front of the machine behind a small flap) and clear any debris. Check the drain hose is not kinked. If the pump has failed, you will need an engineer — pump replacement costs £90–£150.
4. Worn Carbon Brushes
If your machine fills and washes normally but does not spin, worn carbon brushes are a very likely cause on machines over 5 years old. The motor brushes wear down over time and eventually cannot generate enough current to power high-speed spin. This is one of the most common and cost-effective repairs — carbon brush replacement typically costs £70–£110.
5. Drive Belt Broken or Slipping
Some washing machine models use a drive belt to transfer motor power to the drum. If this belt snaps or slips off, the drum will not spin. You may hear the motor running without drum movement. Belt replacement is a relatively inexpensive repair — £70–£120 typically.
6. Faulty Control Board
If the machine completes all other cycles but consistently fails at spin, and other causes have been ruled out, a control board fault is possible. This is the most expensive fault to address — PCB repair or replacement costs £120–£250. A diagnostic visit from an engineer will confirm this.
When to Call an Engineer
If steps 1–3 do not resolve the issue, it is time to call an engineer. A good technician will run a diagnostic cycle, check the motor and brushes, and give you a clear quote before any work begins. Get quotes from at least two engineers to ensure you are paying a fair price.
