Nearly all washing machine cleaning advice is written for front loaders. Top loaders have different parts, different failure points, and a different set of places that need attention, and following front loader advice on one misses most of what matters.
If you have a top loader, this is the version that applies to your machine.
Why the two are different
A front loader has a horizontal drum with a rubber door boot sealing it, and the boot has a fold that holds water. That fold is the source of most front loader complaints.
A top loader has a vertical drum, a lid rather than a sealed door, and it drains downward with gravity helping. It dries out between loads and it does not develop the same smell.
What it has instead is an agitator or an impeller plate, a fabric softener dispenser that is usually part of the agitator, and a gap between the inner basket and the outer tub that you cannot see into. That gap is where a top loader’s problems live.
The monthly cycle
Every top loader needs this and most never get it.
Set the largest load size, the hottest water, and the longest cycle. Let it fill completely with no clothes.
Add four cups of white vinegar, or use a machine cleaning tablet made for the job.
Let it agitate for a minute, then stop the cycle and let it sit for an hour. The soak is the part that does the work, and it is the part people skip by just running a cycle through.
While it soaks, use the water. Dip a cloth in and wipe the inside of the lid, the rim, and the top edge of the basket where it meets the tub.
Then let the cycle finish and drain.
Run a second full cycle with half a cup of baking soda to clear what the first one loosened.
The agitator, which comes apart
This is the part most owners do not know about.
On many top loaders the agitator is a two-piece assembly, and the upper section lifts off. Look for a cap on top, which may pop off or unscrew, with a bolt underneath. Undo it and the upper section lifts away.
What is underneath is frequently unpleasant. Detergent sludge, fabric softener residue, and grime accumulate in the hollow interior and around the base, and none of it is visible from the outside.
Clean it with hot soapy water and a bottle brush, get into the base where it meets the drum, and reassemble.
If yours does not come apart, wrap a cloth around a long brush and clean around and under it as best you can.
Machines with an impeller plate instead of an agitator have a lower, wider disc at the bottom. Same idea, and the underside collects the same material.
The fabric softener dispenser
On a top loader this is usually a cup at the top of the agitator, and it is nearly always the dirtiest part of the machine.
It works by siphon, and softener is sticky, so it builds up into a gummy layer that eventually blocks the siphon completely. Once it blocks, the softener sits there fermenting and it can dump into the drum at the wrong moment.
It usually lifts out. Soak it in hot soapy water, scrub the inside and the siphon channel with a bottle brush, and rinse thoroughly.
The simplest permanent fix is to stop using liquid fabric softener. Half a cup of white vinegar in the same dispenser does the job without the buildup, and wool dryer balls handle the softness.
The places people miss
Under the rim of the outer tub. Run a finger around the underside of the top edge. This is where a slimy film builds and it is completely out of sight.
The lid hinges and the recess they sit in, which collects lint and grime.
The bleach dispenser, if the machine has one. It crusts over and stops dispensing properly.
The lint filter, if it has one. Many older top loaders have a removable lint trap inside the agitator or clipped to the tub rim. Newer machines generally do not. Check the manual, because if yours has one and it has never been cleaned, that is your problem.
The inlet screens where the hoses connect at the back. They catch sediment and a partly blocked screen means slow filling.
The habits that keep it clean
Leave the lid open between loads. A top loader dries out well on its own, and an open lid is the whole reason it does.
Take laundry out promptly. A top loader leaves clothes wetter than a front loader does, and a wet load sitting in a warm drum sours faster than people expect.
Use the highest water level the load calls for. Water volume is the actual cleaning mechanism in this type of machine, and running everything on low to save water defeats it.
Do not pack it around the agitator. Clothes need to circulate, and a packed tub just rotates as a lump.
The New Haven water note
Water here is on the harder side, and scale builds where water sits and evaporates, which in a top loader means the tub rim, the inlet screens, and the dispenser channels.
Vinegar handles scale, which is a good reason to use it for the monthly cycle rather than only a cleaning tablet. Adding half a cup of washing soda to regular loads also reduces how much detergent you need, which reduces the residue that becomes the sludge in the agitator.
The other local factor is old housing stock with laundry in basements. A cool damp basement slows the drying-out that a top loader relies on, so the lid-open habit matters more here than it would in a warm dry laundry room.
The loads a top loader will not do
Even a well maintained top loader has limits. The agitator post means a comforter cannot tumble freely, bulky bedding wraps around it, and the fill volume caps what a big absorbent item can actually get.
The machines at our self-service laundry on Foxon Boulevard have no post in the way and the drum volume for bedding to move freely, plus much higher extraction so it leaves the washer far drier.
Our machines and the store are cleaned daily, which is this whole routine run on a schedule rather than remembered twice a year.
Nou wash-dry-fold service covers everyday laundry when you would rather hand it over.
The short version
Top loaders need a different routine from front loaders. Monthly, fill completely with the hottest water, add four cups of white vinegar, agitate briefly, then stop and soak for an hour, using that water to wipe the lid and the tub rim. The agitator often comes apart, and the hollow inside is usually full of sludge nobody has ever seen. The fabric softener cup is the dirtiest part of the machine and switching to white vinegar removes the problem permanently. Check under the outer tub rim, and check whether your machine has a lint filter. Leave the lid open between loads, and use the highest water level, because water volume is how this type of machine cleans.
