Crawlable reference — same cases as the wizard.
| Symptom | Likely cause | First action | Guide |
|---|---|---|---|
| One radiator cold at the top, warm at the bottom | Airlock in that panel | Bleed carefully with a radiator key over a cloth/tray. Close when water runs steady. Check combi pressure afterward if you have a wall boiler. | Radiators not heating |
| One radiator fully cold; others warm | Closed or seized TRV / lockshield, or stuck pin | Confirm the thermostatic head is open (higher number). Do not force seized valves. If the pin is stuck, book a private plumber. | Radiators not heating |
| All radiators cold, but hot water still works | Heating circuit off, room thermostat/timer, summer/winter mode, or district heat not feeding radiators yet | Check thermostat setpoint, timer, and boiler heating mode. Ask neighbours if the whole stairwell is cold. | Radiators not heating |
| All radiators cold and no hot water | Combi boiler fault, gas/electric issue, or building-wide outage | Note any boiler error code. Ask neighbours. If district-heated with no wall combi, contact zarządca. | Combi not working |
| Whole building / stairwell cold | Heating season not started, ciepłownia outage, or communal pump/valve work | Message zarządca with dates and neighbour confirmation. Private plumbers cannot restart district heat. | Zarządca guide |
| Radiator or valve is leaking (wet floor) | Valve nut, bleed screw, or panel leak under season pressure | Close that radiator’s supply valve if possible, towels/tray under the drip, photograph. Do not remove the bleed screw. | Radiator leak guide |
| Combi pressure keeps falling after bleeding | System leak or failing expansion vessel | Top up once to ~1–1.5 bar per the boiler manual, then stop chasing daily top-ups — book diagnosis. | Combi not working |
