The Ninja Luxe Cafe shows plain-word notifications when it needs something, and one true error family: an "Er" code with a number, like Er 03, which the owner's guide routes straight to customer service at 1-877-646-5288 with no user fix. Everything else on the panel, HOPPER, INSTALL JUG, RINSE, DESCALE, CLEAN, is a request you can satisfy in under a minute, per the ES600 series owner's guide.
Every documented Luxe Cafe notification
| Notification | What it means | Fix |
|---|---|---|
| HOPPER | Bean hopper unlocked or unseated | Rotate the handle clockwise to lock; if it persists, lift the hopper, clear beans from the top of the grinder, reseat and lock |
| INSTALL JUG | Milk jug missing from its platform for frothing | Seat the jug; make sure jug bottom and platform are dry and clean |
| RINSE | Cold drink requested right after a hot one | Run the prompted rinse to cool the path |
| DESCALE | Time to descale | Run the 90 minute descale cycle |
| CLEAN | Time for a clean cycle | Run the 6 minute clean cycle with a tablet |
| TAMP flashing | Grounds are ready to tamp; not an error | Tamp and continue |
| Er + a number (ex. Er 03) | Hardware fault | Contact SharkNinja customer service at 1-877-646-5288 |
The intelligent notification system
The guide lists the full set the machine can display, ADD BEANS, INSTALL PORTAFILTER, INSTALL FUNNEL, INSTALL HOPPER, ADD WATER, INSTALL JUG, RINSE, PURGE, DESCALE and CLEAN, and notes the CLEAN and DESCALE buttons illuminate when their cycles are due. Read them literally: each names the part the machine cannot detect or the cycle it wants. The HOPPER message is the one with a real procedure, because a hopper reseated on loose beans will not lock; clear the top of the grinder before it goes back on.
The two cycles worth doing on schedule
CLEAN runs about 6 minutes with the cleaning disc and a tablet and clears the group head; DESCALE runs about 90 minutes and clears the water path, and the guide warns that ignoring it can clog the machine outright. Keep cleaning tablets with the machine's accessories, and see our Luxe Cafe descale light guide for the full descale walkthrough.
When to stop
Er codes are the machine's own stop sign. The guide publishes no meanings for the numbers and no user procedure; its instruction is the phone number. Note the exact code, keep the machine's receipt handy for the 1 year warranty, and resist the urge to power cycle it repeatedly; once is fine, a dozen times is stress on whatever failed.

FAQ
What does Er 03 mean on a Ninja Luxe Cafe? The owner's guide does not publish meanings for Er codes; its instruction for any Er number is to contact customer service at 1-877-646-5288. There is no documented user fix.
Why does my Ninja Luxe Cafe say HOPPER? The bean hopper is unlocked or unseated. Rotate the handle clockwise to lock it; if the message persists, lift the hopper, clear beans from the top of the grinder, reseat it firmly and lock it.
Why does my Luxe Cafe ask for a RINSE between drinks? You requested a cold drink right after a hot one, and the machine rinses to cool its path before brewing cold.
