Re: cal spa no jets or heater...
It will be hard to pinpoint the problem as it could be something wrong in the control box or it could be a bad pump. The best way to tell maybe would be to unplug the pump cord from the control box and see if you can still hear a clicking noise in the main control box when you turn on the pump button with it unplugged. If you can still hear a noise with the pump unplugged, then it is most likely a bad relay or circuit board. If there is no noise, try plugging in the pump again and if the noises start up again, then it is probably a bad pump. So give this test a try to see if it will help you determione the problem.

That means your "Heating" mode is in Economy!
Without knowing what make our model spa you have, or the manufacturer of spa controls, difficult to assist in telling you how to switch to other modes.
Maybe try this:
Pressing the "Temperature" button and then immediately the "Light/Jets" button may change the system back to Standard?
Once you press those buttons, the "Ec" code comes on and stays on (flashing), and then you can press the "Light/Jets" button to toggle between Standard and Economy and maybe SL - which is Sleep modes.
not sure of the make and model here but sounds to me if you have a heater that "runs away" intermittantly and safety cuts it off this dissallows the pump from running also , carefull temperature monitoring can help you "SEE" this occur and develop a plan to affect a repair on part needed
off hand id say two parts to look at (water temp sensor) and power relay to heater coil for this problem
You have it in "Sleep" mode. Spa will not heat normally in this mode...
If the SL Message is Alternating with the Water Temp in the Display Screen (we call this "Flashing Sleep"), the Spa is Operating in the Sleep Heating Mode.
If the SL Message is ON Solid (Not Flashing) in the Display window of the panel, the Spa is Operating in the Sleep Heating Mode, but there is No current water temperature because the Spa is between Filter Cycles.
Between Filter Cycles, while in the Economy or Sleep Heating Modes, the Pump has not turned ON and the Last Water Temperature is not Current. To read the Current Water Temperature, either Change to Standard Heating Mode or turn On the Heating Related Pump, and wait at least 2 Minutes.
SL or SLP is one of the Modes you can program your spa into:
EC - Economy
ST/Std - Standard
SL/SLP - Sleep
It is advised you keep your spa in Standard mode. Push the Jets button then immediately push the light button. Each press of the light button will scroll between these three modes.
This could be caused by a couple things. In order for your spa to heat your pump must be working, your heater and heater sensors must be good. If your heater is bad usually the breaker will trip. If that's not happening read below... Does water shoot out of the jets when you press the jets 1 button? If not then you have a bad pump or the pump is air locked. The heater can't turn on if the pump does not push water through the heater. You'll know if this is happening because you'll get an error code on your control pad. So your jets are working but no heat. This is the most common problem. Your spa has a sensor that tells the spa if it's ok to turn the heater on. That sensor is prone to failure so everything can be fine but the heater will not turn on. Get the model number off your spa pack and click the link below. Call and tell them you need a pressure switch and give them the model number. Install the new switch and you're back in action.
Depending on which control system your Colman has: Try these: Press & Hold the JET Button for 6 seconds (Most/Gecko & Hydro-Quip)
Hold temperature UP & DOWN together for 6 seconds.
Balboa 7 button controls, both buttons to the left of the display screen & down temperature.
One of the buttons might be stuck in the down position.
most heaters continue to work with the bubble/jets on. The real problem is that when the jets/bubbles are on, it's injecting cool air into the water and effectively cooling the water faster than the heater can heat it. The only way to get the water back up to temperature is to turn the jets and blower off. I assume you're talking about a portable spa. Most portable spas have a 5.5kw heater and sometimes they can't keep up especially if the ambient temperature is lower than the set water temp. Here in southern AZ, we have to run the jets and blower on just to get the temperature down low enough to safely get in the water.
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.
