When an Ergorapido ZB3301 or QX9 does not charge on its stand, verify the outlet, charger seating, dry contacts and room temperature before judging the battery. The two stands are not interchangeable. Align the cleaner exactly as its own indicator diagram shows and compare the first light response immediately after docking. No light points first to power or contact; a repeatable warning pattern after a normal-temperature charge identifies the next official service check. [object Object]

Safety first
- Switch off and unplug, or remove the battery only where the manual permits it. Keep water away from motors, contacts and non-washable filters.
What the symptom may indicate
Checks in the right order
- Make the appliance safe
Switch off and unplug, or remove the battery only where the manual permits it. Keep water away from motors, contacts and non-washable filters.
- Run the official user check
use the original charging setup on a known-good outlet, clean dry contacts and allow the unit to reach room temperature
- Retest once and decide
check the outlet, charger, contacts and temperature before suspecting the battery
Stop and get qualified help when
- Stop for a burning smell, hot or damaged battery, liquid ingress, exposed wire or a fault that returns after one official retest.
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 3 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.
