Bosch classixx dishwasher bottom rack not cleaning

Hi

We have just moved into a new house where the previous tenants had left a Bosch classixx dishwasher.

We have cleaned it with dishwasher cleaner but the bottom tray wasn't cleaning. I have followed the instruction manual by cleaning out the bottom and top spray arm which had a lot of dirt in them. I then checked the filter was clear by popping out the plastic top and checking for any blockages. There were none and there was a little water in the bottom which I cleared.

Still the dishwasher bottom is not cleaning. Does anyone have any suggestions on what I can do before I call out a Bosch technician?

Any help would be great

Thanks

Welcome to the forums! It sounds as if the bottom arm is being restricted in motion more so than being clogged. Will it spin freely by hand? I have had the same situation on a regular dishwasher where a utensil will poke through the basket and lodge against the arm making that washer load dirty on bottom. With the washer empty and running through the wash cycle, quickly open the door to see if water is spurting out the arm. It may give you a hint as to what is happening.

The spray arms getting clogged by minerals, like calcium, is a common problem. It's hard to clean those spray arms as all the crud falls inside when you clean them. When you start the machine all the crud goes back into the spray holes.

It's important that every hole be open as those are also used to propel the spray arm. If the arm is too crudded up it may be better to replace it.
