I have a Deammaker hot tub. The tub works and pump is running. When I turn on the air valve the is no change in jets. The air vave is opening when turned.

Hi Claude.
If your spa jets appear to be pulsating or pausing, first check to make sure your filter isnot clogged. If your filter appears to be okay, you should next take a look at your hot tub's water level. If there is too little water, air could be working its way into the system through the jets.

Intex Inflatable Hot Tub

if your tub was not used for a bit of time your gonn have to pop open the sides and have a look around , Hoses that go nowhere or loose looking are what your looking for, plus water leaks , i did have a problem once with squirels getting inside one and eating hoses off ,made nest inside and generally messed things up inside it but any wild animal could do the same thing

Have you opened the equipment access door and looked in it while it is running. I would look at the pumps to see if one of the seals are leaking. They will leak more on high speed and if you have a cir pump that runs the filter and an additional pump for high speed jet action it would make sense why it is leaking more while you are using it.

Hi,
If your Coleman has Balboa electronics 'PR' is to notify you that it is in priming mode.
It could also be your pressure switch. On most tubs the pressure is mounted on the heater. If this switch is not reading correctly it could shut the spa down to prevent heater overheating.

you can change out the complete air control valve. One thing i would have you do before changing that out is to make sure all of the jet faces are turned on. to do this turn the face of the jet clockwise. this will let the maximum amount of water come out of each jet face.
Sometimes if there are adjustable jets in the tub and they all get shut off, it will force the water that should be coming out of the jet faces back through the system and out the air control knob if it is open.
Just to check. that may not be the case....but...that would be cool if it were.

The problem is that the flow switch for your water heater is indicating no flow. Therefore your water heater will not operate. Without proper water flow your heater will burn up. Check that your valves are open. Check that your pump is running. Check that your filters are properly installed and not restricting flow. Check the wiring to your flow switch and make sure the flow switch operating properly (i.e. put a ohm meter across the contacts and see if you have continuity when the switch closes).

FL could be a code for low flow. If you have no circulation this sounds like it. If your pump runs and you have no flow you could have a problem with your pump. Or if you have the tub drained then it could be an air lock, if you open the drain valve till you get water out that should fix that. Also check to be sure the isolation valves are open under the spa. I hope this helps.

yes my jacuzzi uses air on the suction side to make bubbles. you must have clogged it. how long is tube can you slide a rod in there to check if its blocked?

you might have an air lock, when you first start filling the spa, start the water running in the skimmer first. that should force air out of the pump and should pick up prime right away. if not, you may have a valve problem.
