ᐅ 3 underfloor heating circuits in the bathroom, 1 not working, what should I do?

Hello everyone,
We have now been living in our new house for a week. Our main bathroom is equipped with underfloor heating consisting of 3 heating loops. The spacing of the heating pipes is 5cm (2 inches). Unfortunately, I noticed that one of the heating loops is not warming up, and it happens to be the one under the toilet :-(
What I have tried so far is setting all 3 loops on the manifold to the maximum flow rate, currently at 4 liters per minute (1 gallon per minute). The ERR function is deactivated. The room temperature setting on the heating system itself (heat pump) is set to 22°C (72°F).
What can be observed is that the floor areas with the other 2 heating loops are warming up, but the tiles above the 3rd heating loop remain completely cold. The building handover has already taken place, but the heating system was accepted on the condition that the heating itself works properly, while the heat distribution still needs to be assessed.
Does anyone have any ideas on what else I could try? I assume I can rule out a kinked pipe in the heating loop if I see visible flow on the related flow meter, right?
Thanks in advance,
Best regards

I have never seen such an extremely tight installation in a bathroom before. A wall heating system would have been better, but now it’s obviously too late for that.
Is the 3-circuit system sealed and filled? Is there warm water at the manifold? You should be able to check that, right?

For hydraulic balancing or adjustments, the contractor should be the first to take a look. For the question "can someone take a look at this," I would suggest signing up in the pink forum. Questions like this are frequently discussed there, and it seems that many experts follow the discussions (at least as far as you can tell from their forum responses).
I tried out this newly discovered button – the one for finding images on the topic.
@KingSong From today’s perspective, the commonly held opinion here that a 5cm (2 inch) installation spacing in the bathroom is not good seems a bit odd. This spacing is actually often recommended in addition to underfloor heating. Was your issue resolved?
Your flow temperature was calculated at 35°C (95°F). Are you able to maintain that, and does everything heat efficiently as planned? Even though your system didn’t work perfectly right away, more has been done in your case than in most other “problem cases” here, where installation was done more by feel.
