Check ohms at temp sensors plug both hi limit and temp were not far off of each other for water temp. When spa is plugged in set temp is 100 turn down to spa water temp and shuts off for about 20 to 30 seconds then starts running as if called for heat. Then can not get it to shut down on temp.

Depending upon the age, the Dream Maker has a digital thermostat which is easy to change but to be honest I don't think that is the cause of your problem.
Check the keypad connection on the PCB (circuit board).
t could be either the keypad or PCB at fault and withou trying one or the other you'll not be able to determine the problem. My advise would be for you to contact your local parts supplier and ask them whether or not they can supply you a keypad to try with the option to send it back for a refund if it doesn't cure the problem.
A keypad can be trial fitted to the PCB, just unplug the old one, plug the new one in and turn on the power. There's no need to install the keypad to the spa, therefore you wont damage it in anyway.
If the keypad doesn't cure the problem, change the PCB.

SOURCE: spa won't heat
you need to have the heater tested, there should be about 10 ohms of resistance when testing across the heater leads. MAKE SURE POWER IS OFF, and disconnect the wires at the posts then test for resistance.
If the multimeter reads an open, the heater is bad. Also make sure that you actually get 240 volts across the heater leads when the system is on.
You should have a spa technician test it if you are not comfortable working with electronics.

Assuming that you've got adequate water flow, clean/new filter and the pump works as it should; Try a new sensor. They can and do sometimes fail and the sensor is much cheaper than the PCB. ;)
