Should you fix the leak yourself?

While some simple leaks, such as loose hose connections, might be fixable by a DIY-savvy person, it’s generally recommended to call a professional appliance repair technician for leaks underneath the washing machine. Here’s why:

  • Safety concerns: Washing machines use electricity and water, so there’s a risk of electrical shock if you’re not familiar with the machine’s inner workings.
  • Diagnosing the problem: Identifying the exact source of the leak can be tricky, and a professional can quickly pinpoint the culprit.
  • Fixing the issue correctly: A qualified technician will have the tools and expertise to repair the leak properly and ensure it doesn’t come back.
  • Warranty considerations: Attempting a DIY repair might void your washing machine’s warranty.

Diagnosing & fixing a washing machine leak from underneath (DIY solutions)

If your washing machine is leaking from underneath and you have identified the cause, the next question you’ll be asking yourself is how to fix a leaking washing machine? By following the recommendations below, you’ll be able to solve the problem in a short space of time and enjoy the full functionality of your washer once again.

However, an important reminder before you get started is to always make sure that you put safety first! Always unplug your washing machine and turn off the water supply before attempting any repairs.
Tools you’ll need: Screwdriver, pliers, bucket, rags, flashlight (depending on the leak)

Leak location: Leaking washing machine hoses

Possible cause: Worn or loose supply hoses, clogged or damaged drain hose.
DIY fix:

Is your washing machine leaking from the bottom? Inspect the supply hoses:

  • Look for cracks, bulges or brittleness in the hoses.
  • Tighten any loose connections at the taps or washing machine using pliers.
  • If the hoses show signs of damage, replace them with new hoses following the manufacturer’s recommendations.

Inspect the drain hose:

  • Locate the drain hose where it connects to the washing machine and drainpipe.
  • Straighten any kinks in the hose.
  • Detach the hose from the washing machine and drainpipe (consult your manual, if needed).
  • Use a long object like a straightened coat hanger to clear any clogs inside the hose.
  • Reconnect the hose securely to the washing machine and drainpipe.

Leak location: Washing machine door seal (Front-load washers)

Possible cause: Mouldy, damaged or overloaded washing machine.
DIY fix:

Clean the door seal:

  • Mix a solution of equal parts bleach and water in a spray bottle.
  • Wear gloves and spray the solution on the door seal, letting it sit for 15 minutes.
  • Wipe clean with a damp cloth and dry thoroughly with a clean towel. Regularly cleaning the seal prevents mould growth that can cause leaks.

Reduce the load size:

Avoid overloading the washing machine. Overstuffing can put extra pressure on the door seal, causing leaks. Learn why you shouldn’t overload your washing machine.

Leak location: Dispenser drawer

Possible cause: Clogged dispenser drawer.
DIY fix:

Clean the dispenser drawer:

  • Remove the dispenser drawer completely from the washing machine.
  • Clean any built-up detergent residue with warm, soapy water.
  • Rinse thoroughly and dry completely before reinserting the drawer.
  • Make sure the drawer closes properly after cleaning.

Remember: These DIY solutions are for minor leaks. If the leak persists after trying these fixes, or if you’re uncomfortable with any step, consult a qualified appliance repair technician for diagnosis and repair.

Tips to prevent future washing machine leaks

Our expert tips to help you prevent future washing machine leaks include the following:

  • Inspect hoses regularly: Check your washing machine hoses for signs of wear and tear every few months. Replace them if they show cracks or become brittle.
  • Clean the drain hose: Once a year, clean out your drain hose to remove any accumulated debris that might cause clogs.
  • Don’t overload the machine: Follow the manufacturer’s recommendations for the maximum load capacity of your washing machine.
  • Use the correct detergent: Using the wrong type or too much detergent can create excessive suds and put strain on the machine.
  • Schedule professional maintenance every 1-2 years: Consider having a qualified appliance repair technician service your washer and carry out washing machine maintenance every year or two to identify any potential problems beforehand.
