Question 1

What does error code Error 01 / 05 (Krups EA81 / Evidence) u Krups / Jura / Nivona mean and how to fix it?

Accepted Answer

Two-way water distributor valve fault or hydraulic system blockage. Troubleshooting & fix: Scale-clogged or jammed water distributor beneath the Krups hydraulic cylinder – run a descaling cycle, or replace the distributor assembly and the pair of brew piston O-rings.

Question 2

What does error code Error 09 (Krups) / Jura Error 1 u Krups / Jura / Nivona mean and how to fix it?

Accepted Answer

Faulty NTC temperature sensor or blown thermoblock thermal fuse. Troubleshooting & fix: The coffee machine fails to heat water – measure the resistance of the NTC thermistor on the aluminum thermoblock and test continuity of the thermal fuses (192 °C); replace the faulty sensor or fuse.

Question 3

What does error code Jura Error 8 / Nivona Error 8 u Krups / Jura / Nivona mean and how to fix it?

Accepted Answer

Jammed brew group – drive motor cannot rotate the brewing mechanism cam. Troubleshooting & fix: On Nivona machines, remove the brew unit, rinse it under warm running water, and grease the guide rails with food-grade silicone; on Jura machines, the fixed brew unit must be rebuilt with new piston O-rings.

Question 4

What does error code Jura Error 2 u Krups / Jura / Nivona mean and how to fix it?

Accepted Answer

Internal coffee machine temperature too low (below +5 °C) or disconnected NTC sensor. Troubleshooting & fix: After transporting the machine in freezing weather, let it warm up at room temperature for 2 hours before switching on; if the error occurs in a warm room, the NTC sensor wire is broken.

Question 5

What does error code Krups Flashing Clean + Calc Lights u Krups / Jura / Nivona mean and how to fix it?

Accepted Answer

Complete cleaning and descaling cycle required or leaking thermoblock piston seals. Troubleshooting & fix: Run the full 40-minute maintenance cycle using a cleaning tablet and descaler (never use vinegar!); if water leaks underneath into the drip tray, replace the 2 red silicone O-rings on the tamping piston.
