Hi,
I'm having a problem with an AP213 coffee vending machine. The holding tank will not stay filled to the correct level. It uses a metal rod as a probe to detect the upper level of the tank. When I lift the probe out of the tank to dry it with a cloth it starts to fill. I replace the probe and it will then continue to fill till water touches the probe then shuts off.
I do a few vends and the tank fills and water shuts off. As it should. I leave and it malfunctions later on that day.
Any ideas would be greatly appreciated.
Paul
