What Causes Whirlpool Tub Jets to Stop Working?
Share
There’s nothing more frustrating than gearing up for a relaxing soak, only to realize your whirlpool tub jets are no longer doing their job. No bubbles, no pressure, no massage—just still water and disappointment. The good news is, in most cases, the issue isn’t permanent and can be fixed with the right tools and parts.
At Whirly Bros, we’ve spent over 20 years working hands-on with whirlpool systems. So if your jets aren’t firing like they used to, let’s dive into the possible causes and how to get them back up and running.
1. Clogged Jets or Dirty Filters
This is one of the most common reasons jets stop working—or start blowing weak streams. Over time, mineral deposits, soap scum, and hair can build up inside the jet openings or the internal pipes. If the water isn’t circulating well, the pressure drops, and your tub loses its signature whirlpool effect.
A quick fix is to clean each jet individually. You can soak the jets in a vinegar solution or use a soft-bristle brush to clear buildup. Regular cleaning helps prevent issues before they start.
2. Malfunctioning Air Control Valves
Your tub's air control valve is what mixes air into the water flow to create that bubbly massage effect. If this valve is stuck, broken, or clogged, the jets might blow air inconsistently—or not at all. You’ll need to inspect the valve for debris and ensure it turns smoothly.
If the valve is damaged, replacing it is simple with the right Whirlpool jet tub parts, which we keep stocked here at Whirly Bros.
3. Faulty Jet Pump
The pump is the muscle behind your whirlpool system. If it stops working, your jets won’t push out anything at all. Listen for humming or buzzing from the motor—if you hear it running but there’s no water movement, the impeller might be jammed or the pump may be burned out.
We’ve helped many customers find replacement jet pumps and other Whirlpool jet tub parts that match their model perfectly. Just shoot us the tub info, and we’ll guide you to the right fix.
4. Broken or Worn-Out Switches
If you’re pressing the on/off button and nothing is happening, your air switch or electronic control panel may be the issue. These components can wear out over time or become disconnected. It’s always worth checking the wiring (if it’s accessible) or replacing the air switch unit entirely.
These parts are inexpensive and relatively easy to install—even for DIYers. A lot of times, swapping out a switch is all it takes to bring the tub back to life.
5. Inconsistent Hot Water Supply
Sometimes the jets stop mid-session or lose strength due to a water temperature issue. If the hot water runs out too quickly, the tub might not stay full or warm enough for the system to work properly. This usually ties back to the Whirlpool water heater feeding your system.
If your heater is too small or not heating consistently, upgrading or adjusting the thermostat might help. At Whirly Bros, we’ve also seen older heaters shut down jets mid-cycle because they can’t keep up with demand.
6. Loose Plumbing or Leaks
Leaks in the piping or fittings behind your tub can cause low pressure and poor jet performance. You might not even notice water leaking at first, but if you see moisture under the tub or hear gurgling, it’s worth a closer look. Tightening connections or replacing worn seals often does the trick.
We stock gaskets, hoses, and connectors that are compatible with most Whirlpool jet tub parts systems, making repairs quick and easy.
