A semi-automatic washing machine has two separate tubs: a wash tub with a pulsator at the bottom and a spin tub for drying. Each side has its own motor and its own timer. That design is good news when something breaks, because a fault usually affects only one side, which makes it much easier to pin down.
Common semi-automatic problems
Wash tub not rotating (pulsator not moving)
If the wash timer runs but the pulsator doesn’t turn, the usual causes are a loose or broken belt between the wash motor and the pulsator, a failed motor capacitor, a worn wash timer, or the wash motor itself. Clothes wedged under or around the pulsator can also jam it.
Spin tub not spinning
The spin tub will only run with its lid fully closed, because a safety switch under the lid cuts the motor when the lid opens. A worn switch is the most common reason the spin side stops. Other causes are a brake that stays engaged, a failed spin motor capacitor, a faulty spin timer, or a loose coupling between motor and tub.
Motor hums but nothing turns
A humming sound with no movement almost always means the motor is getting power but cannot start. On semi-automatic machines that is usually a weak capacitor, or something jamming the pulsator or spin tub. Switch the machine off straight away. A motor left humming while stalled overheats and can burn out, turning an inexpensive repair into a costly one.
Water not draining
First check the drain selector knob. Water stays in the wash tub unless it is turned to “drain”. If it is, look for a kinked or blocked drain hose, or lint clogging the drain valve. A worn drain valve seal can also stop the tub from emptying properly.
Leaking from the bottom
Leaks usually come from the drain valve or its seal, a cracked or loose drain hose, or the seal under the spin tub. Water pooling under the wash side often points to the drain valve, while water under the spin side points to the spin tub seal or its outlet.
Timer not working or not stopping
Mechanical timers wear out after years of use. Symptoms are a cycle that never ends, a motor that won’t start at all, or a timer knob that turns without clicking. Replacing a timer is a routine, inexpensive repair.
Loud noise or shaking in the spin tub
Most spin noise comes from an unbalanced load. Spread the clothes evenly and use the spin cap that presses them down. If it stays noisy with a balanced load, the spin tub coupling or its bearing may be worn.
What you can safely check yourself
- Unplug the machine before touching anything inside the tubs.
- Check the drain knob is in the right position for what you are trying to do.
- Close the spin lid firmly. If the spin side still won’t start, the lid switch is the likely culprit.
- Balance the spin load and fit the spin cap on top of the clothes.
- Look for clothes caught around the pulsator or at the edge of the spin tub.
- Check the drain hose for kinks and clean any lint filter in the wash tub.
- Never leave a humming motor running. Switch off and call a technician.

Is it worth repairing a semi-automatic machine?
Almost always. Unless the tub or body is badly cracked or rusted, repairing a semi-automatic machine costs far less than replacing it. See our guide on whether to repair or replace, and our pricing page for typical repair costs.
