The dishwasher has a lock function on it. My toddler has locked the dishwasher. The dishwasher responds as the manual says when you push any wrong buttons. It flashes three times. The manual directs you to hold the lock key for 4 seconds to release the lock. This isn't the first time that this has happened. It took many tries to unlock. I have spent 10 times the time than any other time without luck. I have turned the breaker off for different intervals to see what happens. The frustating thing is the button doesn't always react in the same manner. You can get a series of flashes, single flash, or no response at all. Is there a master reset or bypass function? Any suggestions would be greatly appreciated.
