Symptoms
- No response from buttons after power came back on
- Display is blank or shows an unusual symbol
- Door won't latch or unlatch properly
- Dishwasher worked fine before the outage
Likely causes
- CommonControl board stuck in a fault state from the power interruptionA sudden power loss mid-cycle can leave the electronics in an unexpected state.
- CommonBreaker not fully resetSometimes a breaker looks 'on' but needs to be fully switched off and back on to reset.
- PossibleDoor latched in a mid-cycle positionIf power was lost while the door lock was engaged, it may need a manual reset to release.
- Less commonActual component damage from a power surgeA significant surge during the outage can occasionally damage the control board.
What to do
- Check the breaker panel and make sure the dishwasher's breaker is fully switched off, then back on (not just checked).
- Unplug the dishwasher if accessible, wait one full minute, then plug it back in.
- If the door seems locked, look for a manual door release described in your owner's manual, often near the latch.
- Try starting a short cycle to see if the control board responds normally now.
- Check other outlets or appliances on the same circuit to confirm power is fully restored and stable.
- If the unit still shows no response after a full power reset, a surge may have damaged the control board and a technician should test it.
Tools and parts
- None
When to call a pro
If a full breaker reset doesn't restore normal function, have an appliance technician check for surge damage to the control board.
