After getting a E23 error on my Bosch dishwasher model she3arf6uc/22, we replaced the drain pump. Now it will start a wash cycle, but will not drain and gives E25 code at first drain cycle. There are no blockages and the check valve appears to have no damage. When I hold up on the trip float it sounds like pump is trying to initiate and there is very slight water movement, but will not drain. Any ideas?
