Question about Jandy Laars Lx 400,000 Btu Heater

1 Answer

Our Jandy LX400N does not show any error messages but the water that comes out of the jets is intermittently hot, then cold. I have never heard of a hot tub problem like this. Is there a way to just have the hot water only coming from the jets? We don't see any settings on the display. Thanks!

My Bristan Meridian Show start ok with hot water then after a few minutes the water runs cold. Even if you try and increase the temp it still remains cold. You can switch of the shower and start again...


It sounds like 1 of 2 things to me. I will start wit hot water heater. The first test for the water heater is to have someone run the hot water while you hold the hot and cold pipes and see if the water is coming out of the water heater cold when the shower goes cold. Of the water heater is cold coming out then the problem is in the heater. ether a lower element is bad or the dip tube is broken at the top of the tank. if the hot water heater continues to put out hot water when the shower goes cold then it has to be the mixing valve for the hot and cold mix at the shower and that valve will have to be repaired or replaced. hope this gives you a good start. let me know if I can help further.

No Cold Water Wash; Only Hot


When doing a hot wash the machine is designed to take both hot and cold water. This is because it can heat the water to your selected temperature but if the water coming in is too hot it needs to cool it down to avoid heat damage to your laundry.
Hope this helps & thanks for using Fixya.
