Thetford Tecma Toilet Sensor Issue

[Lukeaa]

The Tecma toilet is the electric toilet with a macerator. It is used where the toilet can not be located directly over the black water tank.

It comes with two sensors that are stuck to the black water tank, to tell you when the BW tank is half full and nearly full. When the nearly full sensor activates, the toilet goes into 'emergency only flush', which means that you have to hold the flush button down for 10 seconds before it will flush.

My problem is that Monaco put the 'nearly full' sensor only halfway up the BW tank, and so the toilet goes into 'emergency only flush mode' when the BW tank is only 50% full. The sensor is placed where I can not get to it to move it, so I am trying to figure out how to trick it. Unplugging it at the toilet control box did not do anything. Does anyone out there have any experience with this issue?

Can you get to any of the holding tank's sensor wiring? Can you get to a point on the sidewall of the tank to add a sensor? If so add another sensor at the point you wish to tell the toilet the tank is full and wire the old sensor circuit to the new sensor.
