Water fountains have some common basic issues, and should be checked for the following, when you here a noise and no water flowing:
1. Is the pump a self-priming? if not, pour some water into the pump.
2. is the water pickup (usually a flexible tube/hose from the water tank to the pump) plugged.
3. if a submersible pump, is the tube/hose to the fountain outlet plugged.
4. If your comfortable with some disassembly, you should isolate the pump and make sure the noise you hear is not a rock or debris stuck in the pump, obstructing the impeller (this is what pulls in the water).

You don't say if there is any water flowing along with the loud noise. If there is none then my suggestion would be that it's a dry water pump so you will need to force some water up the clear pickup tube into the pump while it's making that loud noise. The pump valves will be dry.

It shouldn't make any loud noises at all. Most likely it's a water pump related problem. Most pumps make loud noises when they are lose from their base due to a broken clip or untighten screw. It could also be caused by a faulty pump. Either way, if you just bought it and have the receipt, return it and have them give you another one.

How old is your machine ? and what maintenance have you done over time such as replacing the shower curtain located at the pourring end of the hot water ? I had too very loud noise coming occasionnally from the stainless steel rack holding the cup while coffee is delivered. If your ground coffee is too fine it will stop flow during making a shot. Is water coming out when no coffee is placed in the portafilter.The water pump on this machine is a cheap pump that has to be replaced over time. Mine is 7 years old and has delivered four cups of expresso everyday of the year, and still working.

Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Circulation and Drain Pump Motor

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the motor sound, it's likely that the circulation and drain pump motor bearings have failed. Once this happens the motor will have to be replaced, the bearings are not repairable.

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

If you have a crack in your basket you may have a clogged impeller. With the power off reach back into the pump through the pump pot with a long screwdriver and feel around. If it feels spongey it there you have a clog. Take the serew driver an use an oceleting motion in a counter clockwise direction this should loosen the clog then reach in with a long set of thin pliers and pull the clog out. This should fix your problem and once water is flowing your pump should quiet down.

Most of the time, you just have to reposition the water reservoir - simply pull it up and then put it back in its proper place. If the water tank is even a centimeter off, the suction tube doesn't properly grab it, so it can't take in water.

If you reposition the water tank, and the EM-100 is still not sucking any water out of the tank, there may be a problem with the water reservoir tank itself. Call Cuisinart - I can't remember the Canadian number off-hand (The EM-100C is a Canadian model, so I'm assuming you're in Canada) - and have them send you a new water tank.

Good luck! Let me know if you need any more help with this machine - I am a huge raving fan.
