Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. Do you have a multimeter and are you familiar with testing voltages? Is there an error code?
When you turn the power off then on, do the dots immediately appear or does the pump start up first?
If the pump does come on, does the error code go away when you turn the jets on high?
What about when the jets are on high, same thing?
The pump does come on though? All functions are working except the heating?
The problem is almost certainly the pressure switch. The pressure switch is not being activated from the flow to turn on the heater. Replace the pressure switch and that will solve the issue. If you are quite handy then it is a DIY project but if there is any uncertainty then having a professional take care of it would be recommended. It would only take about 30 minutes.
