we had a kid visiting and he must have fiddled with my dishwasher...it lets in water...then stands and lets it out again..the sprayers don't work nor does the detergent open....I had a support team come around a few years ago and they said to reset the dishwasher you had to push the button in for x amount of seconds...I have no idea how long it was for and what to look out for...please help me..
