Use a thermometer to check the actual temp of the water to see if the units temp probe is accurate. Also what is the max temp allowed by the spas safety program...owners manual.

SOURCE: Spa Heater

You need to check your temp sensor and your high limit. Both are tubes that slide into the plumbing on or near your heater. If this is a tube heater then they are probally at on each end of the heater and will have small wires coming from them that go back to the control board. Farely common problem and easy enough to fix with replaceing them both. A number of models wire them together so they come as one part. Good luck.

My intex spa shows error 96 and 143 degrees F. water is cold

well first the manual should say what a error 96 is but i'll save you the trouble , the control is saying heater failure as the water should never be 143 degrees this would burn/kill you if you got in , id look at temperature probe 1st (its in pipe right past the heater ) and next id look at control itself , sometimes water intrusion dammage in controller makes for some "funny" and wrong things to happen

I have an intex spa and is heated to 96 and it's warm but not hot. What can I do ?

First thing to check would be the filter to make it is clean however if the tub is not getting to 104 degrees as it should you probably have a thermostat problem.

Spa keeps overheating

Faulty temperature sensor should do this to.
A floating thermometer should read water temperature within 3-4 degrees of spa controller. If it is greater than that your sensor is bad.
The hi limit is an over heat sensor it does not control the temperature of the water. If the water is heating above 118 degrees and the spa is not shutting down its Hi Limit.

When you switch the 155xl heat pump on the digital thermometer goes up to 96 degrees and shuts down but the incoming water is 79 degrees.

It sounds like you have a by-pass valve that is open. It should be closed down. You will find this on the pipes in and out of the heat pump. The valve will be between these pipes. When you close it you will force water through the heat pump so it can warm then go back to the pool. Now your water is getting warm then just sitting in the heater. When you close the valve you start the water flowing and their by heating.

I just installed my new X400 Dreamaker Spa. I filled it with water (although cold) and it has been warming up for approx. 18 hours and is only at 80 degrees? Is this normal? How long should it take to...

This is normal with the dream maker spa. The dream maker spas are poorly insulated, and only run 120 volts with a very small heater.
When the unit is first filled, the hot tub will not heat full time either. Most new hot tubs will have freeze protection below 50 degrees F. They will recirculate automatically using the friction and the pumps heat to warm the water above 50 degrees, and then the heating unit will kick on. These hot tubs do not heat while the jets are on high either, so once you are in it using the jets on high, the temperature will start to fall.

Now that you are up to 80 degrees, it should heat up fairly quick however.

Spa / hot tub does not heat

Your temperature control is way out of calibration or, it's wired wrong. Remove it and check it in a glass of water. Use an ohm meter across the heater wires. As you add hot wwater, the heater contacts should open.
