Hi Ian, my name is ***** ***** I will assist with your query today.
To make sure I pull up the right specs to compare to the newer models, can you please provide me with the E number of the device?
There is normally a small plate on the side of the door, however integral units do tend to find ways of hiding the part and serial numbers. Give me some time and ill come back to you with a suitable replacement unit for you.
There is a massive range of Neff dishwashers which would fit the space you have.
A list of models can be found here. Of the list I have checked a few of them and they are fully adjustable to fit within the space you require, for example S51E40X2GB (dimensions are here), or S51L58X0GB (dimensions are here).
My suggestion would be go and look at a dish washer at a local appliance shop, and find one you like the look of and are happy with the trays and compartments, as 80% of user satisfaction is in how easy they are to load and unload. From what I can see in terms of dimensions they use a standard carcass so would expect they should all fit.
Hi Ian, I just wanted to check if you have all the information you require to purchase a replacement or have any further queries.
I would appreciate it if you could rate the service you have received to date.
