Dishwasher and using all in one tablets query

[aveatry]

My last dishwasher a Bosch was replaced in 2021 at 22 years old, it had had a few repairs in its time but nothing major but I put its long life down to first wiping off food with a tissue and then partly rinsing off stuff before it go's in the dishwasher. I once had to clean out the matrix maze of tubes that are made from two pressed sheets of plastic as it was still gundged up with grease stopping the proper flow but that was at about 15 years old.
I figured its cheaper for some paper towel and a bit of water to rinse than it is to buy a new dishwasher or pay for a repair.

So you put down longevity to using it correctly , can’t see any query about tablets , is the post incomplete?

The engineer was sent from Smeg (albeit I assume he was a subcontractor). The instructions naturally say to use salt as it softens the water. But the engineer was saying the salt in the all-in-one tabs is enough and adding salt and using all-in-ones causes too much salt in the water during a cycle.

Water softeners do not add salt to the water.

It is understandable that there are some people who don't know that

But not if they are paid to service dishwashers.
