We have rented a home that currently has a Bosch DLX Series dishwasher. I timed it the last few times I used and it is taking well over 1 1/2 hours to complete a regular wash cycle. Should this take place? If not, what could it possibly be? I do not want to call the landlord unless necessary. I have utilized a Sears Kenmore dishwasher before and it certainly did not take that long to wash the dishes. Thanks.
