Toilet bowl filling up

We have a 2017 Jayco 26BH, the elite model with the ceramic toilet. I just noticed today that the toilet bowl had filled halfway on it's own, and there is a bit of water leaking from where the water comes out when you flush. We are currently in Mexico so I'm hoping it won't be necessary to go searching to see if we could possibly, maybe find a part to fix it. I read that maybe the city pressure is too low to pressurize the lines properly?? We do have super low water pressure here. Or is that just wishful thinking and it's a valve? Any advice or help or home fix ideas are appreciated!

Our toilet did that early this year while we were camping. We just put upward pressure on the floor pedal with our toe for a day or so to stop it. After doing that for a couple of days, it started working correctly. We never knew why it behaved badly for a bit.

Are you using a water filter to remove particulate and microbial matter? Particulate matter in the water could cause valve issues.

If this is a Thetford Style II, I suggest spraying some silicone spray into the water valve.

This is easily accomplished by turning off the water, pressing the foot pedal down, and spraying silicone spray using the straw into the water valve. This has fixed the issue I had with the foot valve not returning to the closed position causing the water valve not to close all the way.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.

Doesn't sound like it should fail so soon. If you leave the pump off it will stop until you can get to a warranty solution.

I plan on installing a shut off valve on mine to try to be ready for this down the road.

Mexican water often gives people "the runs". Maybe it does that to toilet valves, too? Hey, just thinking outside the box.

Thank you for the replies, it has not been as bad this last day or so, so I am hopeful that it is a pressure problem. We also were pushing up on the lever after flushing, and yes, we do have a filter. A shut off valve sounds like a great idea, but since we are in Mexico no warranty work or much of other will be happening. We'll just go with the flow for now and hope it gets better at the next place.
