SOURCE: No heat with Rapid Heat U395000 Jacuzzi jetted tub

when you changed the heater did you make sure you also changed out the temp sensor cause most of the time calciun builds up an is the reason for both the heater an sensor to fail calcium is ok at temps above 93.6 degrees but as soon as the temp drops below this point it will come out of solution an start to harden on the element an sensor.Always make sure to that you are getting power from the spa pack to the heater check for voltage at the main leads on the heater just because it says its on does not always mean you are getting power to the heater.Always remember with spas the problem lies where the power dies.sometimes it can even be your main top side controls they can go bad an indicate the heat is on but will not relay that to the heater.make sure you got the correct kilowatt heater also an that you have the correct one in terms of 240v or 110v also from the thousands of heaters i have replaced in spas over the years i always check to see if i am getting the correct omhs reading before i install them should be around 8-10 for a 110 an 12-13 for a 240

Jacuzzi hot tub will not reach temp pumps do run?


If your hot tub is running but NOT heating then you need to look at a couple of things.
First, on the topside, is the heat indicator light on?
If it is on and the tub is not heating then the temp sensor or the high limit sensor is not working and need to be replaced.

My jacuzzi do not heat up the water anymore and the light on the panel is blinking on the heat light diode


check the pressure switch by bypassing it and see if the heat indicator stays lit.If it is not heating it could be a couple of things. First thing to check is the filter. remove it from the hot tub and see if that solves the problem.if it does not then perhaps the pressure switch is bad.always a chance you have a bad temp sensor if it is running but not heating if the heat indicator light is lighting up.

My jacuzzi is in lock out mode and cant remember how to get it out of that mode


normally this depends on top side layout but on most models you press HEAT button then LIGHT or HEAT then BLOWER.

Hot tub stuck in 'SL' mode


Need to know what buttons your topside control has... depending on the model, some have a mode button which you press and release and then immediately press the temp up or down, to select SL for sleep (no heat), ST for standard (heat as needed) or EC for Economy (only heat during filtration). If the mode button is not present, and you have a single temp button and light button, try pressing and releasing temp and then immediately pressing light button, repeat until choice appears, then wait, it will hold last displayed mode.

Continuous low speed, no heat


At this point after having spent all that money, you have to figure something else is frying those boards.

You need to make a decision whether to A: Call a Jacuzzi repair specialist

B: Replace the the control panel, the board, and possibly even the heater and pump, thermometer and sensors.

C: Cut your losses and buy a new Jacuzzi. Trade this one in on it for whatever you can get. And from personal experience, stay the h*** away from Ebay when it comes to electronics.

MY JACUZZI HOT TUB STOPPED HEATING


sounds like it could be either the heating element, the thermostat or pressure switch problem. Does the light come on when it is trying to heat? if it doesn't come on then most likely the heating element needs to be changed.
