Question: Why Are My Hot Tub Jets Pulsating

If your spa jets appear to be pulsating or pausing, first check to make sure your filter is not 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.

How do I know if my hot tub has an airlock?

As mentioned above, the most common sign that your hot tub has an air lock is the jets not working when powered on. This can include nothing coming out of your jets when they are turned on or even a humming sound coming from the jets or pump.

Why is my hot tub sucking air?

Sometimes if the water level in the spa is too low, a sucking sound can be heard as air is sucked into the filter canister. This is a sure way of getting an air pocket inside the spa, so don’t operate the spa until the proper water level is attained by filling the spa with a garden hose.

Why is my hot tub surging?

A surging hot tub pump happens when the pump in your hot tub stops functioning as designed. The problem is usually diagnosable by the pulsating of the hot tub pump. The cause of a surging pump relates to filter problems, water levels, clogged lines, airlocks, and worn-out pumps.

What is an air lock in a hot tub?

Hot tub air lock happens when air gets trapped inside the plumbing, and the circulation pump is unable to prime. This keeps water from flowing through the water lines, preventing the pump(s), heater and jets from working normally. Whenever hot tub air lock symptoms are noticed, it’s usually pretty easy to fix.

How do I know if my hot tub circulation pump is working?

Check that your power is on, the breaker or GFCI test button are not tripped, all valves are in the open position. Follow the circ pump plumbing, and look for any kinks in the hose. Pull out the cartridge filter to see if flow improves and the circulation pump is doing better.

What causes air lock?

The main cause of an air lock in pipes is when pockets of air are trapped by the flowing water, preventing the free flow of water. Also, cold water pipes have less pressure compared to hot water pipes; as a result, it’s mainly hot water pipes that are affected by air locks.

Where is the air relief valve on a hot tub?

If you own a spa or hot tub that doesn’t have a bleeder valve located in the skimmer area, remove your access panel where your pumps/motors are located. Access panels either lift up and off, use a key to unlock or need to have the screws that are holding the panel removed.

How do you prime a hot tub jets?

Turn the spa on and wait for PR (Priming Mode) to appear on the topside display. Press the JETS button to turn on the pump and let it run for 10 seconds. The pump should be running in low speed. Press the JETS buttons again and let the pump run in high speed for 10 seconds.

What is priming mode on a hot tub?

Once power is initiated to your hot tub it will go through a priming mode. The purpose of the priming mode is to manually activate each spa pump prior to the automatic heat cycle being started. Typically, cycling each pump a few times will prime or purge any air from the plumbing.

Why are my spa jets weak?

When jets start failing, the most likely case is that your hot tub pump is not working correctly. Open the access panel and the airlock valve close to the pump. This releases air from the line and purge system, allowing more water to stream through the jets. Clogged filters or water intakes can also cause jet issues.

Why is my pool jets weak?

The most common reason for weak jets is an air leak. An air leak would come from the suction side of the system. This would be the area between the skimmer and the pump. One way to determine if you have an air leak is by looking for air bubbles coming out of the return jets.

Do you leave jets on in hot tub?

A dip in the spa can be a spontaneous event whenever the mood strikes. Since your hot tub pump circulates the warm water as well as the sanitizer, a general rule is to follow manufacturer recommendations or leave the pump on for a minimum of eight hours per day.

How high should the water level be in a hot tub?

Look for the hot tub filter, normally located on the side of the tub. Fill the hot tub with water to about 2 to 3 inches above the top of the filter. Do not fill the hot tub above this level. As the jets are turned on and people get inside the hot tub, the water level will naturally rise.

How do you prime a hot tub circulation pump?

Control Panel Priming Find priming mode on your control panel (if it’s available). Turn your jets on low for 10–20 seconds. Switch your jets to high for another 10–20 seconds. Repeat until the water pressure is normal and jets are working without any gurgling or air bubbles.

Why is my hot tub pump noisy?

Plug the spa back in and reset the pump. The pump may become noisy if the water flow sensors become stuck or flipped over. Turn the pump off using the On/Off power button on the pump display. Move to the power supply, turn the power off and remove this from the socket.

What does run pumps purge air mean?

Run Pumps Purge Air Display Message Print The purpose of Priming Mode is to allow the user to run each pump and manually verify that the pumps are primed (air is purged) and water is flowing. This typically requires observing the output of each pump separately and is generally not possible in normal operation.

Will an airlock clear itself?

Airlocks do sometimes fix themselves, but it isn’t a risk worth taking. Airlocks occur when air becomes trapped in the hot water or central heating system. Vapour becomes caught in a high point of the pipework because the gas is less dense than the water in the system.

Why do hot tub jets stopped working?

Hot tub jets that are not working can be caused by air leaks, clogged drain covers, low water levels, dirty filters, bad pumps, improper jet adjustment, closed valves, electrical problems, clogged pump impeller, and issues with the hot tub controls. These issues should be troubleshot carefully.
