The last machine Bosch

Our dishwasher from Bosch 4 year old and has always the problem with the sewage pump, the error message E25. The problem with the whole thing is that was developed the sieve in the dishwasher wrong. Once you want to remove the strainer for cleaning, the residual dirt falls into the opening of the drain pump clogged and thus also the drain again. This Zenario repeated every 2 - 3 months. Clean the pump, also extend partially. Meanwhile nervous these actions, and certainly I will not buy a winner of Bosch more.
