Macerator Toilet Won't stop filling-HELP!

[BonusRound1]

2011 Phaeton we've owned a couple of months. This morning after one flush (#1 only) the toilet kept filling and filling even after I kept flushing to keep from overflowing. Any ideas about the problem...and the fix?
Thanks so much.

Find the make and model of your toilet. Go to their site and download the manual for your toilet. If you have the big blue bag, the manual should be in there. It’s probably a stuck valve.

Toilet water supply valve not closing so water continues to fill toilet bowl

Unfortunately......no toilet shut off vale so you have to secure water to RV or turn water pump off until you remove toilet and access backside of toilet to repair/replace water inlet valve

Brand/Model needed for specific info

Ditto old biscuit. Until you can resolve, you may want to consider filling your freshwater tank, then shutting off the outside water. Then you can at least control the water flow by turning your water pump off and on. Not an ideal fix but will be a short term solution.

Thanks all for your helpful responses. Our temp solution has been to cap the water line to the toilet until we can get the replacement valve installed. In meantime, we can have water to shower, washer and full bathroom sink. Can use the toilet, too, by manually filling bowl with enough water to flush after use. For now, it works.
