We have the 18" Bosch dishwasher with the 3 storage racks.  This is our 2nd time purchasing Bosch EVEN though the first one only lasted 6 years. The water pump system is all made of plastic - do not stack plates in front of the water pump hole on the lower back left side - also the cost to repair - I don't recommend even making an effort as we couldn't find someone that really knew how to repair and didn't review the issues proper. NOTHING is made with quality anymore - it's a shame.
