I have a dreammaker X400 spa, the display is flashing on 60. I can turn the temperature up, and the heater will kick on when it gets above the water temperature (currently about 83), but as soon as you release the up button, the display immediately begins dropping back down, kicks back off, and starts flashing on 60 again. We have tried unplugging it and cleaning the filter. Also, the buttons for the jet power and the light will not do anything. Any suggestions?

When you release the up button the display starts going back down as if you were holding the down button? Or does it just go down with the water temp?

It starts dropping as if you were pushing the down button. Stops when it gets to 60 then just keeps flashing.

Sounds like your temp down button is stuck. You'll probably need a new topside control.

Could that cause the light and jet button not to work as well? We used the tub last night and all was fine. Went out later and it was doing this.

Yes, whatever condition (moisture, let's say) caused the button to stick could easily have caused the other two not to make contact.
