If you do not get a light showing on the topside panel indicating it is heating the first thing to check is the filters. Remove them even if they are new. If the problem persists then check to make sure both valves are completely open on either side of the pump so you have not restricted the waterflow.If the valves are open and the filters are removed and the heat indicator light still does NOT come on then you most likely have a bad pressure switch and should be changed.there are a couple of other things that would cause a hot tub NOT to heat but that is the starting place for you.

The bath heater you have is not designed to HEAT water - they only Maintain what you start with.
You need to start the bathtub with the hot water you want. It will only heat about 1-2 degrees an hour.

if the light on the heater is not coming on when the tub is full of water and the pump is on then the heater is not working.
check the circuit breaker to make sure it is on.
the heater and the pump cannot be on the same circuit. They have to be on separate circuits.
Make sure they are on separate circuits.
Check to make sure you have the heater installed in the correct place.
there is a pressure heater that mounts anywhere after the discharge of the pump.
there is a vacuum heater that mounts in front of the pump in the suction line.
if you put on or the other in the wrong place it will never come on.
