The Rivelia has a main drip tray (A14) and a separate red condensate tray (A10). When removing the drip tray, check the red condensate tray and empty it if necessary. This is easy to overlook when investigating water around the front or underneath the machine. The manual also states that the main drip tray has a red float level indicator and must be emptied before that indicator projects through the cup tray; otherwise water can overflow onto the machine or worktop.

Water accumulating in the drip tray does not necessarily mean the Rivelia has developed a leak. Automatic rinsing and operation of the internal water circuits deliberately discharge water into the tray. Empty and dry the tray, refit it completely and monitor how quickly it fills. A gradual accumulation associated with rinsing is normal; water rapidly overflowing or appearing underneath the machine needs further investigation.

The Rivelia monitors the grounds container and drip-tray assembly. Its manual specifically identifies a missing or incorrectly positioned drip tray/grounds container and instructs that the complete assembly should be refitted and pressed fully home, with the side flap correctly closed. If you've recently removed the tray for cleaning, reassemble the cup tray, grille, drip tray and grounds container correctly before investigating an internal leak.

If clear water appears beneath the Rivelia even when it hasn't been making coffee, concentrate on the water supply side. Remove the tank, empty it and inspect it carefully for damage, particularly around the base and outlet area. The Rivelia manual calls for the tank to be removed and cleaned periodically and for it to be correctly repositioned afterwards; the machine also displays a message when it detects that the tank isn't correctly fitted. Refit it firmly and monitor the dry machine to see whether the leak returns.

The Rivelia manual specifically calls for the area accessible after removing the drip tray to be checked approximately once a month. Coffee deposits and residue should be removed using the supplied brush and a sponge, with remaining loose residue removed carefully. This is particularly worthwhile when water appears to be collecting around the tray compartment rather than simply inside the tray. Switch the machine off normally and unplug it before cleaning inside this area.

Dry the Rivelia, tray and worktop completely before testing. If water appears while the machine is standing unused with a full tank, investigate the tank and inlet side first. If it appears during startup or shutdown rinsing, inspect the drip tray, condensate tray and drainage area. If substantial water appears only while a drink is being prepared, an internal hydraulic or brewing-circuit leak becomes more likely. If water is clearly escaping inside the machine rather than being directed into the trays, stop using it and have the internal circuit inspected.
