Float does not trigger valve to stop water - continues to run even though tank is full

Unplug the unit and hold the power button in for 15-20 seconds. Plug the unit back in and try to restart it. It sounds like you just need to reset the cycle. I hope this helps. Also be sure you have the correct amount of water in the unit and nothing is obstructing the float valve.

Do you mean the "Fill Tank" message? If so, I found the problem to be the magnetic switch triggered by the float in the water tank. Please confirm the message you see and I can provide more details.

Ok, it sounds like your unit might have the same problem mine did. I posted some of my findings in this thread:

Adding a magnet to the float helped for several months but then the problem came back. I found the root-cause to be the 'reed switch' (see picture in the other thread) and when I replaced it, it worked fine. Replacement parts like these are often available through web-sites (e.g. http://www.ereplacementparts.com)

There is a float switch in the water tank which is most likely sticking in the downward position. Take out the tank, at the back left you'll see a red piece of plastic. This is the float switch, jiggle it up and down and couple of times and ensure it moves freely, then fill the tank with water and check that the switch rises up with the water level. If this doent solve it, let us know.

I don't know what you mean by "pumping" the tank. If the toilet runs, then either the fill valve is defective or the seal on the flush valve is defective. First, check to see that when you move the float, the toilet stops running. If it does not, then replace the fill valve. If it does, then inspect/replace the seal on the flush mechanism at the bottom of the tank. If this seal is bad, you can usually see water continuously flowing (slowly) into the bowl. You will see ripples on the surface of the water in the bowl.

it sounds like it might be the floater ball in the toilet you can adjust the tension on it usually with a screwdriver.... if you look from the top down you should see a screw on the top of the arm that holds the floater adjust the tension and hopefully this will work

Open the hot water valve, and run about a cup of water, this will engage the pump and fill the circuit.

look on the bottom of the tank and there should be a fitting on there take it off and clean..there should be some hind of float inside the tank.turn it right side up and tap on the tank the float might be stuck

float is sticking make sure it is moving up and down.or the float is set to low, the lower the float is higher the water level is.

I've had this problem. Looks like its the float in the back corner of the water tank, which contains something magnetic that must trigger a sensor. I put a piece of plastic in the float chamber to push the float closer to the side of the tank. Be careful, if you jam the float (in the up position) then you may run out of water without any warning. Very annoying when you can't get your morning coffee.

float valve stuck. try unplugging and then empty tank.check to see that nothing is visable in water reserve. fill water tank to full and then plug unit back in. hope this solves your problem
