I have a high end Whirlpool dishwasher that part way through must change cycles and then several times the pump tries to start, runs for 15 seconds. Then stops and waits for a minute. After awhile it gets past this and completes the entire wash. This does not sound right. But it's possibly on a wash that heats the water it starts, determines it's not hot enough and stops and waits and tries again. New home to me so I am not sure if it did this when new. I may turn off the heated wash option to see if it makes a difference. Other ideas?
