Coffee won't come out of the machine, tried cleaning out the tubes but that just made it worse

You need to advise the model .. but assuming its the CVA 40XX series ... the frist thing to check is the dispenser which has the two pipes comming out of the bottom. This can get coffee residue build up which usually causes 1 or both pipes to have reduced coffee flow. Indication that this is at fault are if the flow is uneven between the pipes or if coffee flows down the outside of dispenser. You can chck this pipework for blocages by openeing door and blowing air though the pipe extending on inside of door. The the dispenser is blocked you need to remove from rear of door and then clean out thoroughly in running water. If this pipework is not and

You need to advise the model .. but assuming its the CVA 40XX series ... here is what I would do;
1. First check is the coffee dispenser on front which has the two pipes coming out of the bottom. This can get coffee residue build up which usually causes one or both pipes to have reduced coffee flow. The indication that this is at fault is if the coffee flow is uneven between the pipes or if coffee flows down the outside of dispenser. You can also check the dispenser for blockages by opening door and blowing air though the pipe extending on inside of the door. The air should flow through easily. If the dispenser is blocked you need to remove from rear of door and then clean out thoroughly in running water.
2. Next check the pump and water path. The pump for the coffee is also used for producing hot water. So if the hot water is working normally then you can rule out the pump. If you not getting hot water then its likely to be the pump or a blockage in the flow through water heater.
3. If above OK then it's a fault with Brew Unit. Follow procedure to remove the brew unit, clean unit and test the air path through both pipes by blowing. Note: When you take out brew unit it not possible to access one of the pipes because its protected by a plastic shield. There is a manual procedure to manipulate the brew unit to expose this pipe so you can blow through it. However the likely cause is not a blockage in these two pipes but the stainless steel filter that the coffee must pass through. You will need an Allen key to remove the bolt holding this in place. Once removed you need to check all holes are free of blockage by inserting a very small wire in each hole. Alternately you can replace this part. If the filter is clogged then you should consider using a different type of coffee as some types coffees cause this problem and others do not.
I hope this helps. regards
