Can I fix this myself?

Yes. This is a user-serviceable condition and the steps above are the ones the manufacturer publishes. If it returns straight after you complete them, stop and book service.

Where do these steps come from?

They are transcribed from Z10 (NAA) Instructions for Use, ch. 8 'Display messages', p.33. We do not repair machines and we do not publish a fix we cannot cite to the manufacturer.

Will this code clear on its own?

Maintenance prompts clear when the cycle they are asking for is completed in full — stopping partway usually leaves the counter running. Fault codes clear when the underlying condition is corrected, not by power-cycling past them.

Fill water tank — Water tank empty

You can fix this

What the machine is reporting

The water tank is empty. You cannot prepare any products.

Likely causes, most likely first

The water tank is empty

What to do

1. Fill the water tank (see Chapter 'Daily operation – Filling the water tank').

Source: Z10 (NAA) Instructions for Use, ch. 8 'Display messages', p.33. Transcribed from JURA's own published documentation — we do not repair machines and do not publish fixes we cannot cite.

When to stop and call a technician

The machine trips a breaker, smells of burning, or shows scorched wiring.
Water is leaking from inside the chassis rather than from the tank, tray or portafilter.
The fault involves the boiler, a pressure valve, the heating element or the pump itself.
The code returns immediately after a correctly completed reset or maintenance cycle.
The machine is under warranty — opening it yourself usually ends that cover.

Never bypass, disable or remove a safety device — a thermal fuse, pressure relief valve or lid interlock is the part standing between a fault and a fire. Do not open a pressurised boiler or work on mains wiring.
