The filter, gasket and drawer are the parts that get dirtiest. Here's how often to clean them, what you need and how to do it safely, step by step.
The drain filter and the door seal are the two points that most often damage a washing machine's operation and odor, and they are also the two that almost no one cleans. Yet it only takes a few minutes and no special tools. A clogged filter leaves dirty water in the machine and sometimes blocks drainage; a neglected seal traps residue, mold and bad odor that then transfers to the laundry.
This is a practical guide: what you need, how often to do it and the exact steps to clean the filter, seal and drawer safely. If instead you're looking for the causes of odors and how to sanitize the entire machine, the starting point is why the washing machine smells.
In brief: what you'll find in this guide
How often to clean
Not all components require the same frequency. Here's a realistic reminder, to be adapted to how many washes you do.
| Component | Recommended frequency | Why |
|---|---|---|
| Door seal | every one or two weeks | traps water and residue, critical point for mold |
| Detergent drawer | once a month | detergent and fabric softener buildup |
| Drain filter | every one or two months | collects lint, coins, residue |
| Hot empty wash | once a month | sanitizes drum and pipes |
What you need
A low basin or some absorbent cloths (water always comes out of the filter).
A microfiber cloth and a small brush (an old toothbrush works fine).
White vinegar or a baking soda and water solution. Alternatively, citric acid for limescale.
No special tools: the filter unscrews by hand.
A safety rule before you start: if you need to work on the filter, it is good practice to turn off the washing machine and unplug it, and work when the machine is cold and at the end of the cycle.
How to clean the drain filter
The filter is almost always at the bottom, behind a small door on the front of the washing machine. Here are the steps.
Prepare the floor. Open the small door and place a low basin or some cloths in front of it: water will come out.
Empty residual water. Many models have a small drain tube next to the filter: pull it out, let the water drain into the basin and close it. If there isn't one, water will come out when you slowly unscrew the filter.
Unscrew the filter by turning it counterclockwise. Remove it completely.
Clean it. Remove lint, hair and any objects, then rinse it under running water and brush it. Also check the seat, inside the machine, with a cloth.
Reassemble it well. Screw it back in firmly in a clockwise direction: if it's not fully closed it may leak. Close the door.
Tip: the first time take a photo with your smartphone before disassembling, so you'll have a reference for reassembly.
How to clean the door seal
The seal is the rubber band between the door and the drum. Its fold is the favorite hiding place for water, residue and mold.
Open the rubber fold by gently pulling it towards you, all the way around.
Remove visible dirt: hair, lint, sometimes small objects forgotten in pockets.
Wipe with a cloth soaked in diluted white vinegar or a baking soda solution, insisting where you see dark spots of mold.
Dry the rubber well at the end: residual moisture is what brings mold back.
If the mold is very ingrained and won't come off, you can let the solution work for a few minutes before scrubbing. Avoid sharp tools that could puncture the rubber.
How to clean the detergent drawer
Remove the drawer. Usually there's a tab or latch in the central compartment to press to pull it out completely.
Wash it with hot water and a brush, removing detergent and fabric softener buildup, especially in the softener compartment and under the cover.
Also clean the space where the drawer is inserted: black mold often forms on the ceiling of that space. A cloth and brush are enough.
Reassemble the drawer when dry.
If you notice the drawer getting dirty quickly, you're probably using too much product. Reducing the dose helps with cleaning and also reduces residue that causes bad odors.
Mistakes to avoid
Opening the filter without a tray: you'll flood the floor. Always prepare first.
Not closing the filter properly: it's the most common cause of small water leaks after cleaning.
Using sharp objects on the seal: a hole in the rubber means leaks and repairs.
Leaving everything wet: after every cleaning, dry the seal and drawer, otherwise mold returns.
Forgetting consistency: a one-time cleaning isn't enough; it's regularity that makes the difference.
The Portos choice
Cleaning the filter, seal and drawer is the simplest and most rewarding maintenance you can do for your washing machine: just a few minutes a month that prevent odors, leaks and drain problems, and extend the life of your appliance. You don't need to buy anything special: vinegar or baking soda, a cloth and a soft brush are enough. It's the classic gesture that costs little and yields much, and it works for any washing machine, regardless of brand. If you're still choosing your model, remember that ease of maintenance counts: we discuss it in how to choose a washing machine.
