On Kärcher FC 5 / FC 5 Cordless, the exact state “rollers stay dry after storage or the gray nozzle button remains depressed” is documented by Kärcher; preserve its display, timing and operating condition before troubleshooting. Prime the cleaner in its station with water for the documented cycle, then confirm the nozzle cover is fully seated. This state alone does not prove an internal replaceable part has failed. Keep codes, maintenance reminders, settings and mechanical symptoms as separate decisions. Switch off and unplug before accessible cleaning. Keep water away from powered parts, never open an internal electrical panel and stop for heat, smoke, exposed wiring or a persistent electrical smell.

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.
