Washing Machine Drain Overflowing Issues
Is your laundry room drain overflowing, but you’re not sure why? There could be several issues here, including installation problems, using an incorrect cycle or clogs in your drain pipes. Here we’ll explore the potential reasons behind your drainage issues, some DIY fixes you can try and when it’s time to call a professional plumber.
Signs Your Laundry Room Drain Is Backing Up
A flooded laundry room is a clear indicator that something’s wrong.
However, sometimes there are more subtle signs you may miss earlier on:
- Slow drainage – If water drains slowly from your washing machine or laundry tub, a partial blockage may be forming in your pipes.
- Gurgling sounds – Do you hear strange noises coming from your drains or pipes? This may mean there’s trapped air due to a clog.
- Water overflow – You might notice water spilling out of your machine and onto the floor during a washing machine cycle (or right after one).
- Foul odors – Is there a stench in your laundry room, but you’re unsure where it’s coming from? Stagnant trapped water and sewer gases from a backup can lead to unpleasant smells.
You may also want to inspect any fixtures near your laundry room, like nearby sinks, toilets, tubs, or floor drains. If you notice any signs of backup, then your problem may actually be coming from your main sewer line.
Common Causes of Washing Machine Drain Backups
If your washing machine usually drains properly, but you run into an occasional issue, then you’re likely looking at a handful of possible causes. These may include overfilling your machine, putting it on the wrong setting or a potential plumbing issue.
You’ve Overfilled Your Machine
A common reason many people encounter draining problems with their washing machine is filling it with too much laundry or using too much detergent. When you put too much laundry in one load, you need more water to fill the basin and wash it. This can overwhelm your drain pipe and cause it to overflow. This issue is more common in newer machines, which often have sensors to determine how much water is needed per cycle.
The Washing Machine Is on the Incorrect Setting
Although a less common culprit, putting your machine on the wrong setting can cause it to overflow. For example, if you are washing a load of delicates and your spin cycle is too intense, or you use hot water instead of cold, your clothes can wear out much more quickly. Excess lint and torn fabric from these items can cause clogs and overflow problems. Similarly, using a light-wash setting with too much detergent may lead to not having enough water to thin out the detergent, causing soap buildup and leading to clogs.
You May Have More Serious Plumbing Issues
Unfortunately, the issue may be with your actual plumbing equipment. To check if your washer’s plumbing is the issue, temporarily route your drain hose into a nearby utility sink if you have one. If the water drains into it just fine but then overflows in the standpipe, then your home’s actual drain line might be the issue. If this is the case, you may need to call a plumber to check for deeper clogs or possibly upsize your pipe.
If your water flow is normal (it should flow at about 3 to 5 gallons of water a minute), then you may have a plumbing issue. In this case, you’ll still need the help of a professional plumber if snaking the line doesn’t do the trick.
How To Stop Washing Machine Drain Overflows
Before calling in a professional, there are a few things you can try. Here are some simple solutions that may fix minor clogs so your drain can flow smoothly again.
Check and Clean Your Drain Hose
Sometimes a kink in the drain hose may cause overflow issues. Check to see that the hose coming from behind your washing machine isn’t crushed, kinked or pushed more than 6 inches into the wall’s standpipe.
Remember, a clogged drain hose is still one of the most common causes of laundry room backups. So, when you disconnect your hose, check it for any blockages or buildup. Use water to flush out any debris and then reattach it.
Clean Your Pump Filter
Most front-load (and some top-load) washers have a small access panel located at the bottom front of the machine. Have a bowl handy for spills and unscrew the filter. Then, make sure to remove any trapped lint, debris or coins inside.
Unclog Your Floor Drain Trap
The trap under your floor drain is supposed to catch debris. However, it can get clogged sometimes. Use a drain snake (or a plunger) to clear away any grease, lint or soap scum. By keeping this trap cleared out, you can keep water from spilling out during a wash cycle.
Use Vinegar and Baking Soda
If you combine baking soda and vinegar, you get a natural cleaning solution that works well to dissolve minor clogs. Pour one cup of baking soda into your drain, and then add a cup of vinegar. Let this mixture sit for about 15 minutes. Then, flush it out with hot water.
Clear Out Your Laundry Tub Strainer
Check your laundry tub to see if it has a strainer for lint or small items that block water flow. By regularly clearing out this strainer, you can keep your drainage system running efficiently and reduce your chances of future clogs.
Flush Your Pipes Out With Hot Water
It may sound simple, but running hot water down your drain for a few minutes can take care of smaller clogs. This is an easy (yet effective) way to keep your pipes clear, especially after you’ve cleaned out other parts of your system.
