Laundry day is routine — until your washing machine starts acting up, leaving you with a blocked, leaking, or smelly drain. In this guide, we’ll walk you through some common laundry plumbing problems and how to resolve them.
Blocked Washing Machine Drain
One of the most common problems with washing machines is a blocked drain. If you notice water pooling around the base of your machine or the drain, something is blocking the flow of water.
First, unplug your machine and turn off the water supply. Next, locate the drain hose at the back of your machine and detach it from the standpipe. Use a drain snake or a wire coat hanger to remove any blockages from the hose or standpipe. Once clear, reattach the hose and test the machine to ensure that it’s draining properly.
Leaking Washing Machine Pipe
If you notice water leaking from the bottom of your machine, it’s likely due to a faulty drain hose. Turn off the water supply and unplug the machine. Locate the drain hose and check for any visible damage or cracks. If there are any, replace the hose with a new one. If the hose is undamaged, check the connections and tighten them if necessary.
Smelly Washing Machine Drain
A smelly washing machine is a common problem due to the build-up of detergent and fabric softener residue. To combat this, run an empty cycle with hot water and a cup of white vinegar. The vinegar will help break down any build-up in the drain and eliminate odours – you can also add baking soda to the mix for an extra boost.
Regularly cleaning your washing machine with vinegar and baking soda can help prevent future blockages and odours.
