HELP PLEASE!!!PYRAMIDA
nneed help. Built-in dishwasher PYRAMIDA DP 09

When connecting the drain, the installers forgot to remove the plug (that is, the drain was tightly closed)
when the drain pump started working, all the water was on the floor.
I found the problem, I opened the plug and started again when draining, all the water was on the floor
I removed the side cover and found the water tank fills up normally, but when it comes in, water gushes through the small window.
Who knows what this window is all about. maybe there should be a plug there, but I didn’t find it.
if the drain hose is at floor level, then with each drain of water a little 50 grams overflows, maybe less, but there is a leakage
if you raise the drain hose at least 30cm from the floor then when draining, all the water is on the floor, although the installation instructions say
that you can raise the drain hose up to a meter

The same thing happened. In the compartment with the dishes there was a strange rubber band that looked like a check valve in the shape of an M6 bolt. It turned out that she was squeezed out of her place inside the plastic tank on the left side. It was squeezed out most likely due to a tee clogged with grease where the water drain is connected. I cleaned the tee, replaced the rubber band and everything was fine
