The BLOC error on your GE Dishwasher means the control lock (child lock) feature has been switched on, which stops the keypad from responding to button presses. It is not a fault with the machine — a simple button sequence held for a few seconds will unlock it.

What the BLOC error means

When “BLOC” appears on the display, it’s short for the control lock function being engaged, sometimes shown as a padlock icon instead of text depending on the model. GE dishwashers include this feature so that curious kids or accidental taps can’t start a cycle or change settings mid-wash. It doesn’t indicate a mechanical or electrical problem — the dishwasher is working fine, just temporarily “locked out” from new commands.

Common causes

  • Someone pressed and held the lock button (often labeled “Heated Dry” + “Start” or a dedicated lock icon) by mistake
  • Kids playing with the control panel and accidentally triggering the lock combination
  • The lock was turned on intentionally and simply forgotten about
  • A power cut or reset that left the display showing BLOC as the panel re-initializes
  • Cleaning the control panel with a damp cloth and pressing buttons unintentionally

How to fix the BLOC error

  1. Locate the lock control buttons — Check your dishwasher’s control panel or manual for the specific button combination used to lock/unlock, commonly two buttons pressed together for 3 seconds.
  2. Press and hold to unlock — Hold the identified buttons down for 3 seconds until the BLOC message or padlock icon disappears from the display.
  3. Check the manual for your exact model — Button combinations vary slightly between GE dishwasher series, so confirm using the model number on the door frame if the standard combo doesn’t work.
  4. Power cycle if the lock won’t clear — Turn off the dishwasher at the breaker for 1 minute, then restore power and try the unlock sequence again.
  5. Test the control panel — Once unlocked, press a few buttons to confirm the display responds normally and start a cycle to verify everything works.
  6. Re-lock only when needed — If you have young children, you can re-enable the lock after loading dishes, just remember the same combination to unlock it later.

FAQ

Is BLOC a real fault code?
No, it’s not a malfunction — it simply means the control lock feature is active and the panel is temporarily disabled for safety.

Why won’t my buttons respond even after unlocking?
Some models need the buttons held for the full 3 seconds; a quick tap won’t work. If it still doesn’t respond, try a power cycle at the breaker.

Can BLOC turn on by itself?
It’s rare, but a power surge or reset can sometimes leave the display showing a locked state. Unlocking it manually should resolve this.
