I don't know this machine, but if you have a coin stuck in a hose then it's usually just a case of disconnecting the hose and squeezing and pushing until you can get a grip of it and pull it out. If the coin is to big to come out of the smaller diameter end that connects to the pump, then disconnect the hose from the other end, the end that the coin went in and squeeze it back the way. If it went in that end it'll come back out that end. By the way, if we are talking about the hose that connects to the bottom of the drum and runs down to the filter, and you do disconnect it at the drum side, make sure that when you put it back on you get it on properly, if you don't there is a danger that the water pressure from the drum on a consequent wash will blow it off again resulting in a flood. Hope this helps. Good luck.
