Not every washer problem needs a service call. Some of the most common complaints, a machine that won't spin, won't drain, or smells off, have a quick check you can do yourself first. Here are five to try before picking up the phone, and how to tell when a check confirms you do need a professional.
The washer won't spin or finish the cycle
An unbalanced load is by far the most common cause. Open the lid or door, redistribute the clothes so weight is spread evenly around the drum, and restart the spin cycle. If it still won't spin after that, the lid switch (top-load) or door latch (front-load) may not be engaging properly, which the machine treats as a safety issue and refuses to spin. A worn drive belt or motor coupler is the next most likely cause, and those aren't a DIY fix.
Water isn't draining after the cycle ends
Check the drain hose behind the machine for a kink or a clog at the point where it connects to your drain. Straighten any kinks and make sure the hose isn't crushed against the wall. Many washers also have an accessible pump filter, usually behind a small panel at the bottom front of the machine, that can catch a sock, coin, or bit of debris. If you can access it, check for anything stuck inside.
The washer smells musty
This is extremely common on front-load machines, where moisture and detergent residue collect in the folds of the rubber door seal. After each wash, wipe the seal dry and leave the door cracked open so it can air out. Run a monthly cleaning cycle with hot water and washing machine cleaner, or a cup of white vinegar, to break down built-up residue. If the smell persists after a few weeks of this, the seal itself may need replacement.
The washer shakes or vibrates loudly
First, check that the machine is level. Most washers have adjustable feet, and a small level placed on top of the machine will show you if one side is higher than the other. Adjust the feet until it's balanced. If the machine is already level and still shakes violently, especially during spin, worn suspension springs or shocks are a likely cause, and that's a repair job.
An error code appears on the display
Modern washers display specific error codes for different faults. Check your owner's manual or search the exact code online for your model, since some codes point to something simple, like a door that isn't fully latched, while others point to a genuine component failure. Writing down the exact code before calling for service also helps a technician diagnose the issue faster.
Signs it's time to call a professional
- You've tried the relevant check above and the problem persists
- You hear grinding, banging, or metal-on-metal noises
- Water is leaking onto the floor
- The machine won't power on at all
- You smell anything burning
If you've gone through these checks and the problem is still there, it's likely something that needs a trained eye. See our washer repair page for more on how we diagnose and fix these issues, including same-day appointments across San Francisco.
Washer troubleshooting questions, answered
Why is my washer not spinning?
An unbalanced load is the most common cause. Redistribute the clothes evenly and restart the spin cycle. If it still won't spin, the lid switch, drive belt, or motor coupler may need attention.
Why does my washer smell bad?
A musty smell usually comes from detergent residue and moisture trapped in the door seal on front-load machines. Wiping the seal dry after each use and running a monthly cleaning cycle usually resolves it.
Can I fix a washer that won't drain myself?
Sometimes. Check the drain hose for kinks and clear any visible clog. If the pump filter is accessible on your model, check it for a stuck coin or sock. If neither resolves it, the pump itself may need professional attention.
