Water problem with Expresso maker

Well as i dont know what machine you have I will give you a generic troule shooting for manual esspresso machines.

first if the steam is working one can make the assumption that the way from the watertank to the bioler is ok.

that leaves us with the handle the filter you put your grindend beans in. Or the filter on the machine.

So first trie and see if it comes out water when you dont have on the handle with the espresson filter.

Will water not come even with the handle off? then its the fitler in the machine. trie and remove it and clean it or trie and descale it and force water through the espresso exit.

Will the water come out just fine with the filter and handle off?
then its those two things.
Trie and put the filter in alitle descaling for a couple of hours and the clean it "extremly" good.

I have a Trevi Combi Plus my problem is when i start doing my coffe water spills out from the border of the filter. and clear water spills into the expresso cup along with the coffee that is being filtered.
