Steamer does not work

Have you tried descaling it? Limescale blockages are common.

If the steamer function is not working on your Cuisinart steamer/convection oven, you can try the following troubleshooting steps:
1. Check Power and Settings: Ensure that the steamer/convection oven is properly connected to a power source and turned on. Make sure you have selected the correct steaming function and set the desired time and temperature.
2. Water Level: Check the water level in the steaming reservoir or water tank. Some steamers require a minimum amount of water to generate steam. Ensure that the water level meets the manufacturer's recommended guidelines.
3. Water Reservoir Placement: Confirm that the water reservoir is correctly placed in the steamer/convection oven. It should be securely seated in its designated position.
4. Steam Vent: Ensure that the steam vent or release valve is not blocked or obstructed. Any blockage in the steam vent can prevent steam from being released properly. Clean any debris or buildup that may be affecting the vent.
5. Steam Function Timing: Some steamers require preheating before steam is generated. Consult the user manual to determine if the steamer/convection oven requires preheating and for how long. Allow sufficient time for the steamer to reach the appropriate temperature.
6. Clean the Steamer: If the steamer has not been used for an extended period, it may have accumulated mineral deposits or limescale. Clean the steamer according to the manufacturer's instructions to remove any buildup that could be affecting its performance.
7. Contact Cuisinart Support: If none of the above steps resolve the issue, it's recommended to reach out to Cuisinart customer support for further assistance. They can provide specific troubleshooting steps for your model or advise on potential hardware issues that may require repair or replacement.
When contacting customer support, provide them with the model number, a detailed description of the issue, and any troubleshooting steps you have already attempted. This information will help them assist you more effectively.

Did you consult the user manual on this?

I examined mine. There is literally NO hole in the steam wand for the steam to exit. It's a wonder the thing didn't blow up. Take it back and be glad you still have your face.

I was able to turn on the steam mop, but no matter how hard I pumped the handle... no steam. Someone here said to put vinegar into the water bottle. I realized that they were saying particles from the water could have formed and clogged the steam tube. First, make sure your steamer is OFF!! Turn the steamer upside down as though you were putting a new pad on, Use a slender object to clean out the tubing where the steam comes from. Again, I will say... make sure your machine is off before you attempt this.. Otherwise, when you clean out the tubing the object will become a bullet flying thru the air and can hurt you, Hope this works

Hi,

Take off the edge on the steam pipe, clean it and mount it again.

The people who manufacture this unit and box it are idots. The manufacturer should that steam can be dangous, and , a user manual should be shipped inside the box. Hey SCUNCI STEAMER dum dums,. Put a printable manual on the site so your customers won,t get hurt by not knowing robert ferriss

Both tubes must be in the water. If you haven't used the machine for awhile, fill the water canister, turn the espresso maker on and also turn on the delivery switch (the top switch on the EC140). You'll hear the pump and in a second or two water will begin to exit the boiler nozzle. Immediately turn the delivery switch off. Wait for the "OK" light to come on. Press the "Steam" switch (the middle switch on the EC140, place an empty cup under the frother and turn the steam control knob on top in the counterclockwise direction. Steam will come from the frother. Be very careful to avoid contact with this steam.

if you could remove the pipe put the pipe in a solution to remove the calcium in thr pipe dry calcium is like concrete dip it and use a piece of wire to clean cheers

To remedy this, I did the following:
1) Removed screws from: a) Lower area of handle (1 screw), b) Top of steamer, under round rubber flap around fill hole (2 screws), c) Front of steamer where nozzles attach (2 screws)
2) Removed back of handle, top of steamer, front of steamer where nozzles attach 
3) Once all parts are removed, you can see a brass button that is pushed by the trigger
4) Using a needle-nose pliers, grasp and rotate the button several times in both directions (you may hear it cranking against the interior spring). Do this until it turns fairly easily with the pliers.
5) Once this is done, you fill find that the brass button can be very slightly depressed with a bit of force. You may also need/want to unfold a large paper clip to push into the nozzle hole to help unsticking the brass button (not sure if that helped in my case, but it was something I tried along the way). When the brass button moves in and out (again, it won't move much), the steam release mechanism is unstuck!
6) Reassemble all parts (everything snaps back neatly into place).
This worked for my unit!
