Water UFH Thermostat comes on then immediately goes off - Tile Advice

[Dan85]

Hi, I'm hoping someone can help. I'm in rented accommodation (house built 2 years ago) that has a combi boiler & underfloor heating in the kitchen and living room. Last winter it was working fine, but now the living room thermostat is playing up. When it is set to a high temp, the red light comes on as if to draw heat, but then shuts off - nothing happens with the boiler. The kitchen thermostat is working fine. What could be causing this?

Here's a video of the thermostat
