Dishwasher Won't Start
Pressing Start and getting nothing — no hum, no lights, no fill sound — usually isn't a mystery. It's almost always one of a small handful of things: power, the door, a stuck button, or a control board that's already locked itself out.
What this looks like
The most complete version of this symptom is total silence: no lights, no display, nothing at all when you press any button, which points toward power rather than the dishwasher's internal logic. A step down from that is a dishwasher with lights on and a display active, but pressing Start does nothing — no fill, no motor sound, sometimes an immediate beep of rejection. A third version is a dishwasher that appears to accept the Start press, runs for a second, then stops, which usually means it began the cycle and then immediately hit a fault rather than failing to start at all.
Most likely causes, ranked
- The door isn't closing and latching within the expected window. Most models require the door to be securely latched, and on some, closed within a few seconds of the Start press — see the door latch page for the full breakdown.
- No power reaching the unit. A tripped breaker, an unseated plug on plug-in models, or a blown fuse feeding the circuit will produce total silence.
- A physically stuck or sticky button on the control panel, which some brands report as its own distinct fault rather than a simple non-response.
- A control lock or child lock engaged on the panel, which will make every button press appear to do nothing.
- A control board or user-interface fault that has put the unit into a halted state, requiring a full power reset to clear.
Which error codes this can show as
- Whirlpool: F1E1 (control module fault, internal error halting operation), F2E1 (a stuck key detected as permanently pressed), and F5E1 (door latch not detected as closed)
- KitchenAid: F1E1 (control module fault) and F2E1 (stuck-key / user-interface fault)
Bosch, Samsung, and LG don't have a documented code in this dataset specifically for "won't start" as distinct from the door-latch and control-fault codes above — on those brands, a unit that won't start is more often signaled by a blinking light than a lettered code, or the cause is simply the door not being latched. See blinking lights with no error code if that matches what you're seeing.
What you can check yourself
- Confirm the dishwasher has power: check the breaker, or for plug-in models, that the plug is fully seated
- Close the door firmly and try pressing Start again within a couple of seconds
- Press and release each button on the control panel firmly to check whether one is physically sticking, and wipe down the panel to clear any sticky residue
- Look for a control-lock or child-lock indicator and hold the lock button (often 3 seconds) to release it if engaged
- For plug-in models, unplug for 30 seconds and plug back in; for hard-wired units, flip the breaker off for 30 seconds, then restore power and try a new cycle
Call a professional when
If power is confirmed present, the door latches normally, no button is stuck, and a full power reset still doesn't get a cycle to start, the control board or user-interface assembly likely needs professional diagnosis and replacement.
