Jura Error 22: CLARIS Smart Filter Not Recognized - Fix It in 5 Minutes

Quick Answer: Error 22 means the machine could not read the RFID chip on the CLARIS Smart water filter. Remove the tank, pull the filter, reseat it firmly until it clicks, and refill. If the error returns, fit a new genuine CLARIS Smart filter. If a new filter still fails, the RFID reader in the tank base has failed, usually from water damage. That repair is $200-$300 in the US. In the meantime, set the machine to no filter and keep descaling on schedule.

What Error 22 Means

Jura’s current machines use the CLARIS Smart filter, and its successor the CLARIS Smart+ and Smart mini. Each one carries a small RFID chip. An antenna coil in the base of the water tank holder reads the chip when the tank goes in. That is how the machine knows a filter is present without you telling it, and how it tracks the filter’s remaining capacity. It also writes to the chip, so a used filter cannot be reset by moving it to another machine.

Error 22 is the machine reporting that this exchange failed. Jura’s technician documentation is specific: “CLARIS Smart communication problem; RFID information could not be written; there is a defect in the CLARIS Smart filter, the CLARIS Smart module, or the CLARIS Smart antenna”.

Three parts, in order of likelihood: the filter, the antenna coil, the reader module. The filter is by far the most common. A few online sources describe Error 22 as a “critical motherboard error” on the J8, Z10, and GIGA. That does not match Jura’s own documentation or US parts suppliers, both of which tie Error 22 to the Smart filter system. The fix starts with the filter, not the motherboard.

Which Jura Models Show Error 22

Any machine that uses the CLARIS Smart RFID system:

• Current: E4, E6, E8, S8, J6, J8, J10, Z6, Z8, Z10, WE6, WE8, X6, X8, X10, D4, D6, ENA 4, ENA 8, GIGA 6, GIGA 10.
• Not affected: older Impressa machines that use the CLARIS Blue or CLARIS White cartridges with no chip. Those have no Error 22.

Our CLARIS filter guide lists which filter each model takes.

The Five-Minute Fix

Step 1: Reseat the filter

1. Remove the water tank and empty it.
2. Pull the CLARIS Smart filter straight out of its holder in the tank.
3. Check the filter’s base and the holder for debris or scale.
4. Push the filter back into the holder until it clicks. It must be fully seated. A filter that is a few millimeters high sits outside the antenna’s read range.
5. Refill the tank with fresh water.
6. Dry the base of the tank with a cloth. Water on the tank base is what damages the reader over time.
7. Reinsert the tank firmly.

If the machine starts normally, you are done. Many Error 22 reports come from a filter that was pushed in at an angle after a refill.

Step 2: Try a new genuine filter

If reseating did not help, fit a new CLARIS Smart filter of the correct type for your model. An RFID chip can fail, especially on a filter that has been dropped, frozen, or stored in a damp cupboard. Third-party filters without a compatible chip are another frequent cause. The machine may have accepted the filter at first and then failed to write to it.

Insert the new filter, and if the machine prompts, confirm the filter change in the menu. Our best CLARIS filters guide covers where to buy genuine ones.

Step 3: Confirm the machine is otherwise fine

Go to the settings menu and set the filter option to off or no filter. Remove the filter from the tank. If the machine now runs without Error 22, the machine’s hydraulics and boards are fine. The problem is confined to the RFID system. You can keep using the machine this way while you decide on a repair. Descale on the machine’s prompts, since without a filter the descaling interval becomes shorter. Our guide on using a Jura without a water filter covers the trade-offs.

If the fix above clears the code but it returns on the next filter change, the cartridge is the wrong type or its chip is faulty. Buy the filter your model specifies:

When Error 22 Is a Repair

If a new genuine filter still triggers Error 22, the reader has failed.

RFID antenna coil

A flat coil in the base of the tank holder. It corrodes when water pools under the tank, which happens when the tank is reinserted with drips on its base. The coil for the D, E, ENA, GIGA, J, S8, WE, X, and Z ranges is about $65.

RFID reader module

The small board that drives the coil and talks to the logic board. Two versions exist, one with a 230 mm cable for the D4, D6, E6, E8, J6, S8, and WE, and one with a 370 mm cable for the ENA, GIGA, X6, X8, Z6, Z8, and Z10. About $90 either way.

Both are moderate jobs. The parts sit at the front of the machine under the tank, which is easier to reach than the thermoblock or brew group. A technician usually replaces coil and module together if there is any water damage, because both were exposed.

What Error 22 Repair Costs in the US

This is one of the cheaper Jura repairs and worth doing on any machine you plan to keep. The alternative, running with no filter and descaling more often, is workable but costs you time and descaling tablets every few weeks.

Model-Specific Notes

Jura E8, E6, S8: Reader module with the shorter 230 mm cable. Reseating the filter solves most cases. Dry the tank base before every reinsert.

Jura Z10, Z8, Z6, GIGA: Larger tank, longer 370 mm reader cable. The Z10’s tank is heavy when full, and setting it down with water on the base is the classic way to soak the coil.

Jura ENA 4 and ENA 8: Use the CLARIS Smart mini. The smaller filter is easier to seat at an angle. Push it in until it clicks.

Jura J8 and J10: Same system as the Z10. If Error 22 appears right after a filter change, the new filter’s chip was not read; reseat it and confirm the change in the menu.

Preventing Error 22

• Dry the base of the tank every time you refill it. This is the whole story for reader damage.
• Use genuine CLARIS Smart filters, or third-party filters with a confirmed compatible RFID chip.
• Store spare filters dry and at room temperature.
• Push the filter in until it clicks, every time.

Related Error Codes

• Error 6 - ceramic valve fault, the common consequence of running without a filter in hard water.
• Error 5 - thermoblock not heating, the other scale-related fault.
• Error 8 - brew group fault.

Frequently Asked Questions

What does Error 22 mean on a Jura?

Error 22 means the machine could not communicate with the CLARIS Smart water filter. Every CLARIS Smart filter has a small RFID chip. The machine reads it to know a filter is fitted and writes to it to track usage. If that read or write fails, the machine shows Error 22. Jura’s documentation calls it a CLARIS Smart communication problem.

How do I fix Jura Error 22?

Remove the water tank, take the filter out, wait a moment, and push it firmly back into its holder until it clicks. Refill the tank and reinsert it. If Error 22 returns, fit a new genuine CLARIS Smart filter, or select no filter in the machine settings to confirm the machine itself is fine.

Can a third-party filter cause Error 22?

Yes. Non-Jura filters without a compatible RFID chip, or with a chip the machine cannot read, are a common cause. The machine may accept them for a while and then throw Error 22. Switching back to a genuine CLARIS Smart filter usually clears it.

What if a new filter does not fix Error 22?

Then the RFID coil or reader in the machine has failed, often from water reaching it when the tank was reinserted with water on its base. The coil is about $65 and the reader board about $90. With labor, expect $200-$300 at an independent US shop. Until it is fixed, set the machine to no filter and descale on schedule.
