Press start and the washer just sits there: no hum, no lights, no lock click. Before assuming the control board is dead, check the handful of things that stop most washers from starting at all.
Part of the washing machine troubleshooting guide. If the washer starts but then gets stuck partway through, see washing machine stuck on spin cycle.
Quick Diagnosis Table
| Cause | Likelihood | Difficulty | Typical Cost |
|---|---|---|---|
| Door or lid not fully closed | Very likely | Easy | $0 |
| Tripped breaker or unplugged power cord | Likely | Easy | $0 |
| Control lock engaged | Likely | Easy | $0 |
| Cycle paused or delay start set by mistake | Possible | Easy | $0 |
| Door lock mechanism failed to engage | Possible | Moderate | $20–40 |
| Main control board failed | Rare | Professional recommended | $150–300+ |
Repair or Replace?
Nearly every cause on this list costs nothing to fix. Even a door lock mechanism replacement is a modest, affordable repair on most washers. A control board failure is the one expensive path worth weighing against the machine’s age.
Door lock and control lock combinations differ by brand: Whirlpool, GE, Samsung, LG, Bosch, KitchenAid, Frigidaire, and Maytag each use their own sequence, usually printed in the manual’s quick-start section.
Frequently Asked Questions
The display lights up but pressing Start does nothing, is that different from a fully dead machine?
Yes, a lit display with an unresponsive start button points more toward a door lock or control lock issue rather than a power problem, since the board clearly has power.
How do I check if the control lock is on?
Look for a small lock icon on the display. Hold the designated lock button, often shown in your manual, for about 3 seconds to release it.
Can a slightly overloaded drum prevent the door from locking?
Yes, if laundry is caught in the door seal or door edge, the door may look closed without fully engaging the lock sensor.
Should I try unplugging the washer for a few minutes?
Yes, unplugging for about 5 minutes clears many minor control glitches and is worth trying before assuming a part has failed.
