Why does my Ninja brew more water than specified?

Same problem here. Just bought today and searching for an answer. Have you called customer service ? Mine brews 4oz over on every setting.

"Ok here is my theory. This is a known defect and the date codes for these models are in the Nov/Dec time frame. I bought returned to bed bath and got another all around the same date codes. Both have the same problem. ( 4oz above what they should be). Could it be they are try to move these through a discounted price at B&B. They are lower than any other supplier

I am going to push hard on management to get resolved"

I have the same "overdispensing" issue, in addition to the cleaning light being on all the time to spite the multiple cleanings. They replaced once, but now want $20 shipping to do that. From what I can see on line, there have been lots and lots of failures with this product. They know that most people won't pay the $20 shipping. I think a class action suit is called for, so we can all get our $100 or so back.

"Interesting to see that this fault still exist. I bought one from Amazon and got it yesterday. It gives way to much water.

Mug 400ml. Should be 250ml

Travel mug 700ml should be 379ml

Half carafe 1100ml. Should be 577ml.

So for full carafe i did not try as i assume it will overflow.

This is for sure a known problem for Ninja. If they claim they want shipping money for a new product that seems so wrong. They should of taken all of this machines off the market and take the hit for hit. I dont feel happy to be a “free"" final tester for Ninja and dont get paid for it ;-)

What do you guys have for numbers under THE machine after modell namn? Should be in silver

"looks like you have it set to Rich brew according to the manual which will give you slightly more. (page 12 or 13 of the manual)

Update (12/30/2017)

Actually you may have over-filled the reservoir. The cup or travel mug may not have been empty prior to brewing.

""The water exceeded the Max Fill line on the water reservoir prior to brewing.
