My Jets Arent Working

HOT TUB Topside Control Panel Not Working Right ?

If you wanted to lie around in warm, unmoving water, youd just take a bath. One of the best parts of soaking in a hot tub is using the jets. But if youve got nothing coming out of your jets, dont fret.

Try the easiest and least expensive solution first: turn each of your jets to make sure theyre all wide open. Also, check them for debris such as calcium buildup, and clear them if necessary. Top off the water, clean your filter, and check for plumbing line clogs.

Did you recently refill your hot tub? If so, you could have airlock. You can turn your jets on and off a few times to try to force the air out. You may also loosen the top fitting on your pump just until you hear air escape and see a bit of water, then tighten it back up.

Important: No matter what you may have heard, we do not recommend using a plunger on your jets. The force of plunging may damage your circulation system. It may also void your warranty. Then you really will be paying a bunch of money for repairs.

What If The Error Code On My Hot Tub Control Panel Isnt Erased

If the error codes still pop up after you reset the control panel, then the control panel has an inner problem. It could be a faulty wiring, a water problem, a corroded connection, or some other issue with the control panel. To be sure, you will need to turn off the tub and check the control panel to see what the problem is.

Hot tubs have two types of control panels the handheld control panel and the in-built control panel. The handheld panel is usually connected to the hot tub with a cable and the in-built control panel is usually placed on the top of the hot tub or the side of the hot tub.

Your hot tub will have one of the two. Both types of control panels are always sealed with a waterproof seal to ensure water doesnt get in. After all, the panel is used on a hot tub.

If you have the handheld control panel, check the panel and both ends of the cable that connects it to the hot tub. If you have an in-built control panel, you should check inside the service bay for the cable that connects the panel to the tub.

You might also need to open the control panel to check if it is wet, has a faulty wire, or if is damaged. As a precautionary measure, if you find out the control panel has a faulty wire or a corroded socket, it would be best to contact an electrician except you are experienced with hot tubs electrical set up.

Identifying The Problem When Hot Tub Is Clicking

Coleman Hot Tub Control Panel Not Working

If you want to troubleshoot a gadget, the first step should be detecting the problem.

Begin it by testing the voltage of the receptacle. You can use a multimeter for this purpose. Normally a hot tub requires either 110-120V or 220V. The required voltage depends on the tubs power.

If your receptacle fails to provide that voltage, your tub might click but not work. And if the required voltage is provided then your gadget is problematic. So, youll need to work on that.

In case you dont have a multimeter in your house. We would suggest you get one. To make it easier for you, weve added our best picks here-

Hot Tub Control Panel Not Working

For most people who own hot tubs, the issue of hot tub control panel not working is something theyll have to deal with sooner or later. Most people even ask themselves: How do I reset my hot tub control panel?

Issues with the main control panel in your hot tub can cause a world of problems for you. Its incredibly infuriating to come home after a tiring day at work, only to find that your hot tub is not working properly.

However, in most cases, all it takes is a basic reset to get rid of the problem and get your hot tub back in order. But, you may find that a single reset doesnt do the trick and you will have to reset it multiple times to get it working.

This is not something that you should ignore. Its an indication that theres something seriously wrong. If there is a flashing light in the panel or you hear some sort of beeping, its also something that you need to worry about.

To reset the main panel, you need to turn off the hot tub and then give it a break for around 30 seconds before you turn the hot tub on. If you still receive the error signal, you may want to check the official instruction manual that came with your hot tub.

If the panel does not work at all, you might want to take a close look at the main connections and see if theres any water in there. Moisture in the main panel could spell a lot of trouble.

Checking If The Plugs And Wires Are Okay

Firstly, well start with the plugs and wire. Check if your connection plugs and wires are in the right place or not. Try replugging and recheck. Theres a high chance of it not working if the wire is spiraled or twisted.

If the plug and connection wire has dust on it, it might have a problem functioning. So, try to clean the plugs with a soft piece of cloth. Then try again.

Also, ensure that youre using the right wire or not. Some wires work fine with lights only. Whereas others are perfect for high voltage appliances.

Wires obviously play an important role to ensure the gadget is working properly. So, making sure your wires are in good condition is necessary. Moreover, wires might need some replacement over time. Keep that in mind too while youre planning to troubleshoot.

These methods might not solve your problem. But its better to start with checking the hardware before taking a drastic decision. We can try other ways mentioned below if this step fails to solve the problem.

Your Hot Tub Control Panel Is Not Working And Displaying Errors

Although they show something is wrong, sometimes hot tub error codes can be confusing and dont necessarily pinpoint the cause of the problem. Manuals have many error codes. The five common error codes include:

  • FLOW: Appears when there is improper flow. You may also see it when your jets misbehave. Check for blockages, clean or replace your filter and determine if the circulation pump is working.
  • OH: Appears when the water is too hot to use. Check your circulation system and filter. Also ensure your pump is not running for very long periods. You may need to replace the temperature sensor. But if the display appears and your water is not hot, it is advisable to call hot tub experts.
  • DRY: Means insufficient water is getting to the heating element. You may have to top your hot tub. Please use a hose filter to prevent impurities from getting into your spa and plumbing system. Double check to make sure no debris is present in your circulation system before restarting.
  • COOL: Appears when the actual water temperature is 20 degrees lower than what you set it at. Place your hot tub cover back and allow the heater to run for 24 hours.
  • SNA / SNB: Sensors A and or B might be going bad or sensor circuit has problems. You may need to get a new sensor. Call an expert if youre uncomfortable or unsure.

Sometimes, restarting does help in such a situation.

  • Make sure there is no moisture in the display

Any visible dampness underneath the display is not a good sign for the control panel. Remove the panel from the hot tub shell, peel off the membrane, and sponge out the moisture carefully.

  • Check if the connection cable is intact

Nuisance rodents can gain access to your hot tub and cause damage like cable crimping. You may want to take a look at the cable that connects the control panel with the main circuit board in case you find your controller not working all of a sudden.

Some switches on the panel may still work if this is the case. Youll need to remove the side paneling of the tub to have a good look at the cables there.

  • Brush and clean the plug-ins on both ends of the cable

As you check the cable down there, plug out the connection jacks and brush them clean. Brush the sockets as well. Make sure no electricity is running to the tub while plugging in or out.

  • Check the transformer

Make sure the transformer on the control circuit panel has electricity running through it. A faulty transformer can keep your control panel from working efficiently. Consider professional help if youre not good with electronics.

Hot Tub Topside Controls Not Working Right?

Last Reply on August 17th, 2022 by Nigel

II have a 2002 Optima spa. Several months ago the button on the top-side control panel for the 2 speed pump stopped working. Theres a second, smaller control panel on the opposite side of the tub which also will not work. But when the preset filter cycles occur the pump will come on and the icon comes on on the display. I tried shutting off the power and unplugging the control panel from the electrical panel, and then replugging everything in but its still the same. There also was a time where the pump was coming on and off all on its own, sometimes several times / minute. Is my control panel toast?
