when the dishwasher runs, is it like i think, and it pulls in cold water, heats it up in the bottom, pings the tablet in then uses that water to fling round the machine, or like hubby thinks, the water goes through the drawer with the tablet in and disolves it? Or something different?
It should be obvious. If you open the machine at the end of its cycle, and the tablet compartment is open, then its like Panic Button says. If the compartment is still shut, then it's like your hubby says.
