Why your Unox combi oven is water not filling
Here's how water not filling typically presents on a Unox combi oven: cycle starts but no water enters. Water inlet valve, hoses, or float switch. More often than not it traces back to a clogged inlet screen. Left unaddressed, the kitchen loses a station it can't work around.
Most likely causes
- Low household water pressure
- Failed water inlet valve
- A clogged inlet screen
- Control board timing fault
Known Unox combi oven weak points
- Limescale scaling in steam/spray system in hard water
- Fan motor bearing wear
- Door gasket wear
- Touchscreen or control board faults
Quick check — and when it's not DIY
One thing you can rule out on your own: check the inlet screen for mineral buildup or debris if you can access it without tools. Also, check that the water supply valve is fully open and the inlet hose isn't kinked. When that isn't the fix, if water still isn't reaching the unit, the inlet valve or an internal sensor has failed, and replacing those safely means shutting off house water and opening the cabinet.
