On Avanza and Solo Perfect Milk, a water symbol that remains lit with a full tank first calls for reseating the tank and checking its float and outlet valve. The two families use the same first-line check, but keep their removable parts separate: compare the model label before ordering a tank, float or valve. If the symbol clears on one machine after reseating, that result does not prove that a visually similar part fits the other family. [object Object]

Safety first
- Keep water out of the bean hopper, grinder and electrical openings. Never force a brew unit, valve, grinder control or hot steam part.
What the symptom may indicate
Checks in the right order
- Confirm the model and signal
Confirm that the displayed or observed condition exactly matches “fill-water symbol stays on with a full tank” before changing anything.
- Prepare the appliance safely
Complete the normal shutdown, unplug the machine, let hot parts cool and empty the drip tray before removing user-accessible parts.
- Carry out the official user check
Remove the tank, reseat it squarely; if the light remains, empty it and shake gently until the level float moves freely, then refill.
- Interpret one controlled retest
Reassemble every part in its documented position and run one short rinse or one beverage. A repeated signal after the stated check requires service rather than repeated resets.
Stop and get qualified help when
- Stop and contact the manufacturer if the same signal returns after one correct cycle, a grinder contains a foreign object, a hot-water leak appears or the machine trips power.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
