When the jets on your walk-in tub stop working, and there is no sound and no water when you press the water button, the cause is usually power or a loose air signal hose rather than a failed pump, and the first thing to check is the GFCI outlet serving the tub. Ella push buttons are pneumatic: the chrome button sends a puff of air down a thin tube to a relay in the control box, and the relay switches the hydro pump on. If the jets worked the first time and now nothing happens, or the water massage stopped mid bath, a tripped GFCI, a tube off its nipple or a trapped pulse of air in that tube explains most cases. The deeper guide is pump or massage system not working.
Likely Causes
- The GFCI outlet or breaker feeding the tub has tripped.
- The air signal hose has come loose at the control box nipple or at the button.
- A pulse of air is trapped in the hose, so the relay never receives the signal.
- The pump was run with the water below the jets, which damages it.
- A control box or pump fault, which the team confirms after the checks above.
What to Check, in Order
- Reset the GFCI outlet serving the tub (it may be behind the access panel) and confirm the breaker is on. If the outlet trips again, stop and have an electrician look at it.
- Remove the front access panel and look for the green power LED on the control box. Lit means power is reaching the box; dark with a live outlet points to the box or cord, see the control box reset guide.
- Push the air tube from the water button firmly onto its nipple on the control box with a twist and push, then check the button end as the video shows; push button air hoses and ports maps each hose to its port.
- If the hose is on at both ends, disconnect the tube at the relay, let it relieve for a moment, and reconnect it. Press the button and listen for the relay click.
- Confirm the water is 1 to 2 inches above the highest jets before pressing the button; see how much water before turning on the jets.
- If other functions or indicator lights on the tub still work but the pump stays silent, power is reaching the equipment and the hose, relay or pump is next.

When to Open a Ticket
If the GFCI holds, the green LED is lit, the hose is secure at both ends and the pump still will not run, contact your Ella dealer or the team at (800) 480-6850, or open a ticket at ellasbubbles.com/support. Include your serial number, your therapy package, a photo of the control box with its LED, and whether the relay clicks when you press the button. The team confirms the part from your details.
