How to connect if the hoses are short? ⇐ General questions about dishwashers

[अर्घः]

Good afternoon I ask those who know the answer to answer.
We were planning to buy a dishwasher, the manufacturer, in my opinion, is Veko, but that’s not even the point.
When we looked in the store, short hoses caught our eye (offhand - 1-1.5m), and one hose (apparently for supplying water, but I could be wrong) is removable, i.e. If you wish, you can buy and attach a longer one, but the other one (apparently for draining water) goes inside the dishwasher, and the same short one, I can’t imagine how to replace it. I planned to place the dishwasher not next to the drain, but at a distance; hoses will need a maximum of 2.5-3 meters for both water intake and drainage, therefore, the standard installed hoses are no longer needed, longer ones are needed. But, after reading several instructions from different manufacturers, I saw that extensions are strictly prohibited. But not everyone has a dishwasher located a meter from the drain; surely there are those who have it further away, how did they connect it?
The only thing the sales people could advise was to call the manufacturer’s hotline, but there, they called 2 numbers, Apparently, New Year’s coma - they don’t answer the phone. What should I do?
