No floor heat in aft bathroom...

Weve noticed that the floor is no longer heating in the aft bathroom. I know that it works on the same circuit as the bedroom and the floor heat there is working fine. Breakers, GFI plugs in the midship bathroom are all fine.
Is there anything I should be looking for in the basements, engine compartment or anywhere else for that matter. We are heading into colder climates and it would be great to have our heated floor for morning showers.
Any insight would be greatly appreciated. 2016 DS 4018.

Had the same exact issue in our '15 LA. Found a circuit breaker that had popped located underneath right side lav in rear bath. Maybe your coach has the same setup?

I know configuration can be different. I have two GFI outlets above my circuit breaker panel. Those GFIs are for my floors.

Everything was working fine, until it wasn't.

Thanks to both of you. No luck finding a circuit breaker under the sink and yes I also have those circuit breakers. In fact there are three. The third is in the medicine cabinet. All three serve a specific switch for the floor heating. What gets me is that the aft bathroom and the bedroom are on the same circuit and the bedroom floor is heating just fine. Would anybody know where the thermostat is located for the aft bathroom floor?

No thermostat that I know of. Its all time based depending on the selection of low, medium or high. I would power everything down completely, then restart.
GFIs should show green lights. Check connections at the KIB panel in the rear. Should hear relays engage at that panel.

Though our floor plan and model is different, we had the same issue. It turned out to be a GFI in the rear bath under the sinks up high up on the wall.

Just had my bedroom floor heat repaired. On mine the bedroom and back bath are served by one relay. Both zones are wired into one relay, perhaps a twist nut has allowed the bath zone to lose its power. You will need to remove the cover from the junction box under the sinks and check power there. At its worse, like mine the power grid broke and will need repaired. Be sure to take your extra tile with you to CN.
