There’s a lot of appeal to running your washing machine overnight. Not only do some energy providers offer lower rates during off-peak hours, but few things beat the feeling of waking up to fresh, clean laundry – without having to wait for the cycle to finish.
While this may seem like the ultimate money- and time-saving hack, it turns out it might not be the best idea after all, with experts warning about one hidden danger, which also applies to using a tumble dryer at night.
To find out what it is – and whether you should stick to daytime cycles instead – keep reading.

No, it is not safe to run your washing machine overnight, as it could pose a fire risk to your home.
"I would strongly advise against running appliances, such as washing machines, while you’re asleep. In the unlikely event that they catch fire, you’ll be less likely to notice and take safe action quickly," says Ian Palmer-Smith, appliance repair expert at Domestic & General.
Sunaree Ko, an electrical and fire safety expert at Fire Marshal Training, agrees, explaining that the majority of washing machine fires are caused by electrical, overheating, or mechanical failures – issues you won't notice if you're asleep.
A safer alternative? Using the timer function on your washing machine to start early in the morning, advises Ian. This way, you’ll be awake while it runs, without needing to remember to switch it on. Just make sure you’ll be at home for the duration of the cycle.
As an extra precaution, you could plug your washing machine (or any other appliances, for that matter) into an RCD circuit breaker, which helps prevent electrical shocks and fires. You should also install a safety alarm nearby so you’re alerted to any issues, Ian adds.
This RCD safety plug will help keep both you and your appliances safe.
Ian Palmer-Smith is a supplier and heating service director at Domestic & General and a domestic appliance service and repair expert with over 35 years of professional experience.
Before founding Fire Marshal Training in 2024, Sunaree worked as a Fire Safety Trainer and a Fire Risk Assessment Assistant.
How do I prevent a washing machine fire?
As previously mentioned, using an RCD circuit breaker is an excellent preventative measure against washing machine fires. These can be picked up on Amazon for under £15 and used with other household appliances.
Sunaree Ko also recommends ensuring your machine is installed according to the manufacturer’s instructions. This includes using the correct voltage, avoiding overloading the electrical circuit, cleaning the filter regularly, and avoiding the use of old or faulty units.
What are the signs of a faulty washing machine that could catch fire?
Concerned about the safety of your washing machine? Here are the warning signs to watch out for, according to Ian Palmer-Smith:
- A burning smell – "caused by overheating motors or components, faulty wiring, loose electrical connections or damaged drive belts overheating"
- Loud or abnormal noises – "indicates motor faults, electrical component stressor a damaged or slipping drive belt"
- Visible smoke – "urgent sign of overheating or electrical failure"
- Machine running hotter than normal – "a motor may be overheating, electrical components may be failing, or there are blockages may be preventing proper cooling"
As someone who used to run their washing machine overnight all the time, I’ll definitely be reconsidering my laundry routine and switching to daytime cycles instead – it’s just not worth the risk.
