We have a 2-3 year old Kenmore dishwasher that has developed a leak underneath. It seems to occur during the wash cycle and not during draining. A local tech suggested I change the sump which I did. All parts looked to be in good shape except the diverter motor. It had dried up soap on it. The leak also seemed to come from this area. I read that the seal for the diverter shaft is a common problem, but the sump included a new seal.

The leak continues unchanged. Could it be the diverter motor itself or is the main pump that is close by a more likely cause? Thanks in advance for any assistance
