The filter has to be changed at least after 12 months*, or as soon as the filter capacity has been reached. The remaining capacity of the filter is shown in the cooler display, on the Watersystems app (relevant for GROHE Blue Home and Professional) or on the flow meter or exchange timer (relevant for GROHE Blue Pure).
An LED display in the faucet’s left handle makes it easy to tell when filter capacity is running low. If the residual capacity is <10 %, the LED on the handle flashes and, depending on the settings, you receive a push notification telling you the filter needs to be replaced soon.

When the time comes to replace the filter, the display on the tap will alert you with an orange, blinking light.
Using a GROHE Blue Pure Watersystem, the flow meter or filter exchange timer give an acoustic signal when the filter capacity is exhausted.

(*UltraSafe filter has to be replaced after 6 months.)

This can be done according to the table overview in the printed manual.
Once the filter is replaced, press the left button of the cooler and hold it down until “rF” starts flashing on the display. Then release the left-hand button and press it again until “rF” stops flashing. The message “99” will now appear (= residual filter capacity). The filter capacity has been reset.

If you use the GROHE Watersystem app, then you can easily reset the filter capacity as well on the app.

On the GROHE Blue Pure system, the reset of the filter capacity is done on the flowmeter or filter exchange timer. This can be done according to the description in the printed manual of your system.

When you don´t use the system between 2 days and 4 weeks. you need to flush with about 3-6 litres of water before drinking, to get rid of the stagnated water. After 4 weeks or even more of no use, you should exchange the filter and clean the system with the GROHE cleaning cartridge.
