Varianza CSP may stop drawing milk when the steam tube is loose at the container lid or the milk hose is loose at the outlet or container. When cool, reconnect the steam tube and both milk-hose ends fully, then run Easy Cleaning before one milk-foam test. A clean, sealed circuit that still draws no milk needs service; do not enlarge hose openings or force the steam outlet. This exact symptom does not by itself prove that an internal replaceable part has failed. Finish the automatic shutdown, unplug and let hot or pressurised parts cool. Keep water out of the bean hopper, grinder and electrical openings.

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.
