When designing our products, we choose our materials very carefully. We also consider how these materials are put together, with an eye towards functionality, practicality, ease of use, and maintenance. We’ve designed a mesh Safety Net into our water boilers, and this small component protects the dispensing mechanism in a smart way.
The Safety Net is a small, basket-shaped piece of metal mesh, fixed to the bottom of the inner containers of our water boilers upside-down. It prevents pieces of limescale or other debris from entering the dispensing mechanism, which pumps water so it can be dispensed. Limescale, which is generally comprised of calcium and other minerals naturally found in water, can build up inside the water boiler through normal use. Over time, limescale flakes off into small pieces that can get into the dispensing mechanism of the water boiler, preventing the machine from working properly. The machine makes a “grinding” sound when water is dispensed and eventually breaks. The mesh Safety Net acts as a filter that blocks rogue flakes of limescale from entering the water boilers’ dispensing mechanisms, and as a result, protects it.
Aside from making sure the filter is always in place when in use, we recommend treating your water boiler with our Citric Acid Cleaner once every three months. Doing so will remove limescale even before they flake off. Simply dissolve one packet of the Citric Acid Cleaner in a cup of warm water. Pour the mixture into your empty water boiler and fill the inner container with water. Close the lid and turn the machine onto the cleaning cycle, as per the instruction manual. Once the cycle finishes – usually about an hour later – unplug the machine and empty out the water. The final step is to rinse and dispense resulting in your water boiler becoming just like new! Check out our instructional video and if you ever lose your Safety Net, remember that a replacement can always be purchased from our Parts & Accessories store!

Hi, are there any videos explaining how to reinstall the filter? In the water boiler I purchased, the filter fell out of the spot and I can’t figure out how to put it back in.
Hi Rina, instructions on how to reattach the filter for your water boiler is included in the instruction manual which are available here: https://www.zojirushi.com/support/manuals_waterboilers.html Please turn to the “Cleaning and Maintenance” part of the manual for directions with diagrams.
Hope this helps!
Question: I just saw where there is a Prop 65 California warning on the mesh filter due to the nickel which is known to cause cancer. I love the water boiler. Can I use it without the mesh filter?
Hi Sherry, we don’t recommend removing the filter since it prevents any large debris from going inside the water boiler and clogging the passage of water. Nickel is an important alloying element in food-grade stainless steel. It provides high anti-corrosive properties to the stainless steel (surgical steel contains nickel). The mesh filter is made of high quality food-grade stainless steel and is completely safe to use.
Please note that the warning doesn’t mean that our product is unsafe or not up to the product safety standards by the FDA. In fact, the California government has clarified that the fact that a product bears a Prop 65 warning doesn’t mean by itself that the product is unsafe. For further information, please go to http://www.P65Warnings.ca.gov .
Hello, I just re purchase CD-WBQ 22. From my experience using the previous one, I’m wondering how to remove and attach back the mesh net filter without scratching the surface of inner hole? As my old one I saw the coating peel off on some part of the inner hole ( as a result of the friction when remove and attach the mesh net obviously). Is that coat with the non stick coating material too? Please advise. Thanks
Hi May, the filter should be pulled out, cleaned, and replaced before performing a citric acid cleaning. Over time and use the nonstick coating may experience wear, this is normal. This will not affect its performance or sanitary properties and is harmless to your health. Please let us know if you have any questions!
I lost my mesh filter, so I checked your store, it is out of stock, and I can’t find it anywhere else, when can I buy a new one? Thanks so much.
Hi Elaine, please reach out to our Customer Service for assistance in locating the part or add you to a notification list: https://www.zojirushi.com/app/customer_service/entry
I have a CD-LCC30 water boiler. The inside container non-stick coating is starting to peel. Can this be replaced?
Hi Jer, first we would recommend performing a citric acid cleaning to make sure it’s not mineral deposits. It’s very rare that the nonstick would peel as it usually is caused by scratches on the surface. However, if the nonstick coating is indeed peeling, then the liner may be replaced by an authorized service center. Please contact your closest authorized service center and they will be happy to help!

The screen netting where it meets the bottom seems to be rusting. Please advise. Does this mean the entire unit needs to be replaced?
Hi Erren, the “rust” is iron deposits that have accumulated. Please try performing a citric acid cleaning as recommended in the instruction manual. This process should descale any mineral accumulation on the surface of the water boiler. Please let us know if you have any questions!

CV-DSC40 Safety Net, is there one from another model that will fit this
Hi Albert, I’m so sorry but at the moment the mesh filter is out of stock on our parts and accessories shop. Please reach out to our customer service team and they can double check on the actual inventory and add you to a notification list. They would let you know as soon as it’s available.

Hello, I used a citric acid tablet and now there’s an orange spot at the bottom of my CV-DCC40 water boiler. The spot feels rough to the touch. Is the water boiler still safe to use? Is there a way to fix the discolouration?
Hi RL, usually an orange spot is iron that accumulates from the water along with some calcium. This mineral will accumulate if the water boiler is not properly descaled. Please reach out to our customer service team and provide them with more details. They will be able to provide you with troubleshooting assistance and recommendations: https://www.zojirushi.com/app/customer_service/entry
Hello,
The mesh filter on my kettle was out of place for a long time and completely clogged with calcium. Without having the filter in place I just used the citric acid to clean the kettle of calcium. It took several rounds/ days of soaking because the build up was severe. Now the water won’t dispense but I can see that the pump is working. I believe that a bit of limescale is stuck in the dispenser and is blocking it. Is there a way to fix this? Thanks! Liz
Hello Liz, if the clog is severe, the water boiler will need to be inspected and repaired by a service center. There is one more thing you can try before that though. You will need a cup of lemon juice from a bottle. Do not use fresh lemon juice. Pour the juice into the water boiler and then fill it up to the max line. Then start a cleaning cycle by pressing and holding the reboil button. The cleaning cycle will take about 1-1/2 hours and after it’s done switch the water boiler to keep warm. Keep the lemon juice water solution in keep warm over night. The next day dispose of the water and don’t try to dispense any of it. Make sure the solution has cooled down before disposing of it. After fill it up with just water up to the max line and boil the water. Once the water is boiled try to dispense some of the water. If this still doesn’t allow you to dispense, then you could try this process again but it’s likely it will need to be inspected and repaired by a service center. Hopefully it does work and the water boiler is up and running again!
