Why Does My Washer Drain Smell Like Sewage?
There is a wide variety of laundry detergent available today, each designed to tackle different stains more effectively than others. While certain detergents may offer better solutions than others, all will provide effective clothing cleaning results.
But sometimes your washing machine or laundry room may smell of sewage, here are some reasons and solutions for why this might be happening.
Dry P-Trap
A p-trap is an integral component of drain systems. The “U”-shaped bend in the pipe contains water that acts as an effective barrier against sewer gasses (including methane, sulfur dioxide and hydrogen sulfide) from coming up through your drain and becoming an irritation or even potentially hazardous for you and your family. Therefore, having an operating p-trap in your home is absolutely vital!
Your P-Trap could have dried up for several reasons. Most commonly, this occurs when your laundry room hasn’t been used recently and its water evaporates. Another possibility is incorrect installation of the flexible hose connecting the washing machine to the P-Trap – pushing too far down can allow sewer gasses to escape instead of passing through to fill up its capacity in the P-Trap.
P-traps can also become dry due to broken vacuum seals or blocked vent pipes, so make sure to flush a toilet or pour water down a drain at least every two weeks to maintain optimal conditions in your p-traps and drain lines. Mineral oil addition may be beneficial as well in maintaining good condition throughout your plumbing system.
If the smell of sewage remains, professional assistance could be in order. They’ll quickly pinpoint its source and be able to make repairs accordingly.
Your home’s plumbing also includes vent pipes to direct sewer gasses away from your house. These vent pipes typically run up and out through the roof, but can become blocked by animals, leaves, snow or debris. If this happens to your vent pipes, clearing away debris may require you to climb on to your roof to clear away blockages; alternatively a professional plumber has all the skills and equipment needed to unclog your vent pipes quickly without climbing up there yourself.
Clogged Vent Pipe
Your washing machine, like other drains in your home, should be vented to ensure sewage gasses don’t escape into your living area and create an unsafe situation. If it smells of sewage when being run, the vent pipe may have become blocked causing a smell from within the machine itself or outside – something to consider in this situation if this smell persists.
Vent pipes that lead from your laundry drain to the roof allow air to move through your plumbing system and balance pressure when water flows down a drain, helping balance pressure as water drains off of it. But when these vents become blocked by build-up of debris or filth, sewer gases cannot escape, leading to buildups of bacteria resembling sewage odor. A plumber can be hired to clear away clogs and clear pipes.
One possible source of the smelly laundry room could be an overfilled detergent tray containing old fabric softener or detergent that needs washing; to remedy this situation, simply ensure it’s cleaned regularly to keep its trap clear of debris.

Clogged Detergent Tray
If your washing machine reeks of sewage, the cause is likely clogs. Clogs are one of the primary culprits behind sewer odor in homes; they can lead to food spoilage, mold growth and health concerns for you and your family. Luckily there are steps that you can take to mitigate their smell while protecting both yourself and your house’s safety and wellbeing.
Regular inspection of your washer and dryer for clogs is important in preventing them from becoming serious issues down the road. If you do detect a clog, however, it’s crucial that you immediately call in a professional as a clog may lead to sewer gas leaks which could endanger you and your family’s wellbeing – they contain hydrogen sulfide gas which has powerful carcinogenic effects; inhaling this gas may even prove fatal in extreme circumstances.
However, professional help may be required in some instances to address a clog in your washing machine. A trained expert can identify its exact cause and suggest solutions to address it effectively.
Apart from checking the p-trap and vent pipe, it is also vitally important to clean out your detergent tray and dispenser drawer. Detergent build-up in these areas may create unpleasant odors; clearing this area out will eliminate odors while improving machine functionality.
Your washing machine could also be emitting an unpleasant stench due to an empty P-trap. P-traps are designed to trap sewer gasses before they enter your home through drain openings; however, when left unused for extended periods, their contents can evaporate leaving behind an unpleasant aroma in both your laundry room and throughout your home.
Carefully managing sewage odor in your laundry room is vital for the wellbeing of both you and your family. Sewer gases contain toxic materials that emit an unpleasant rotten egg smell; in addition, they pose a fire hazard due to methane gas being highly flammable.
Home Plumbing
Drain pipes that direct dirty water away from a washing machine are connected to your plumbing system, meaning any issues with home plumbing could impact them as well. Food particles or grease buildup in these drain lines could result in your washing machine emitting an unpleasant stench when in operation, prompting regular checks for blockages as well as clearing out your grease trap regularly. It is wise to inspect these systems regularly in order to maintain good hygiene standards in your kitchen sink area and to clear out your grease trap at least every month.
One common cause of laundry room odor is when the washing machine drain hose isn’t connected properly, often due to machine movement, location changes or other circumstances affecting its position. Reconnecting it is usually enough of a solution – often done simply by rehooking its opening in the wall.
If your stinky washer cannot be identified as the source, consider hiring a plumber to inspect and perform necessary repairs or maintenance on it. A professional is sure to know where to look for issues you might not have considered previously.
Maintaining proper ventilation in your laundry room is the best way to combat sewer odors, using an exhaust fan will help circulate the air and eliminate odors trapped in small, humid spaces for extended periods. Furthermore, maintaining regular maintenance tasks for both the exterior and interior of your washing machine, such as regularly clearing away detergent tray residue or clearing drain hose clogs can make finding and fixing any potential issues much simpler and faster than letting problems fester unnecessarily.
