Why is my washing machine not draining?

If your washing machine won’t drain, there could be several likely causes. The wisest move is to get a professional to diagnose and resolve the issue quickly, but you can also take a look yourself first to see if it’s a really quick issue to solve.

In this article, we’ll take you through a few reasons why your machine might be struggling to drain, and what you can do about it.

What causes a washing machine not to drain water?

It’s pretty apparent when a washing machine is not draining because the bottom will be full of water and sometimes the door may not open. This can result in that wash load not being cleaned properly as it is effectively swimming in dirty water. It’s a sure sign that your washing machine needs attention before it can be used again.

If your washing machine refuses to drain, start by examining the drain hose, a critical component in the drainage process. Check for potential blockages, freezing, or bends that might impede the smooth flow of water. A kinked or twisted drain hose can disrupt the drainage, leaving water lingering in the tub. Beyond the drain hose, several common culprits could be contributing to this issue. Here’s an easy-to-follow guide to the most common issues:

  • Clogged Drain Hose: Ensure it’s free of obstructions.
  • Blocked Pump Filter: Regularly clean to prevent drainage restrictions. Learn how to know when your washing machine filter is blocked and needs to be cleaned.
  • Faulty Pump: Consider repair or replacement if the pump malfunctions.
  • Obstructed Drain Pump: Inspect for foreign objects hindering the pump’s operation.
  • Faulty Lid Switch: Check if a malfunctioning lid switch is affecting drainage.
  • Drainage System Issues: Investigate blocked pipes or faulty connections.
  • Excessive Suds: Use the recommended amount of detergent.
  • Faulty Pressure Switch: Address issues with the pressure switch regulating water levels.

For DIY enthusiasts, checking the drain hose and pump filter regularly can help maintain proper drainage. However, if issues persist or if you’re unsure about the diagnosis, seeking professional assistance ensures a thorough and accurate resolution.

What to do if your washing machine is not draining

Drain with an emergency hose:

Before any troubleshooting can begin, you’ll need to consider how to drain the water from your washing machine. Emergency washing machine drainage is a quick, temporary fix but won’t resolve the underlying problem causing the blocked machine in the first place. Nevertheless, it’s an important step to take. First, turn off the power. Not all washing machines are equipped with an emergency hose, especially older models, so bear that in mind. Emergency hoses can sometimes be found in the service hatch of a washing machine – but check the user manual for your personal model. Drain into a bucket or tray.

Drain manually

If you don’t have an emergency hose, remove the main drainage hose (located at the back of the machine if not internal) and place it in a bucket, and simply allow gravity to do the work. If the drainage hose is internal, this may be a job for a professional instead, who will not only drain the machine, but can also give an accurate diagnosis and swift resolution to your washing machine woes.

Check for kinks in the drainage pipe

Pull out your washing machine and take a look at the drainage pipe at the back. If it looks kinked, then straightening it out could resolve the issue.

Check for blockages

A common cause is blockages which can impede the washing machine’s functionality – a telltale sign can sometimes be nasty washing machine drain smells, such as rotten egg odours. Like anything, appliances may become blocked with debris from the household, such as fluff, soap, residues and harder items. First, drain the water using step one and two. Then simply use your instruction manual to untwist the filter out and check for blockages, removing them if found. Try and start your washing machine again to see if this has fixed the issue.

Still not working?

Another possibility is that the pump is broken, or there is another internal problem. Either way, this isn’t something that a non-professional should attempt to fix – if you suspect a broken pump or other issue e.g. wiring problem or main control board (“brain” of the machine), a professional will not only confirm this diagnosis for you, but they can correct the issue quickly and safely.
