The cord with one blade turned sideways is not a wrong part and nothing is missing. It is a 20 amp, 120 volt plug, often called a T-blade plug, and it is designed to plug into a 20 amp receptacle only. The correct fix is to have a licensed electrician confirm the outlet is on a 20 amp line and install a 20 amp GFCI receptacle, which is a standard item at any hardware store. Support has also pointed customers to a 15 amp to 20 amp T-blade plug adapter when a standard household outlet is already in place.

Why One Plug Looks Different

Ella walk-in tubs with pumps use two cords and two outlets. One cord ends in a standard household plug and the other ends in the 20 amp plug with one horizontal blade. The 20 amp plug is on the control box cord. A 20 amp receptacle has a T-shaped slot that accepts either blade orientation, while a standard 15 amp receptacle has two vertical slots and will not accept the horizontal blade. Which cord goes where is explained in which cord plugs in where, with photos of the boxes in identifying control boxes, cords and air tubes after installation.

The Right Fix: A 20 Amp GFCI Receptacle

The receptacle for the control box cord needs to be a 20 amp GFCI on a 20 amp line, and it is available at your local hardware store. This is a simple swap for a licensed electrician when the circuit is already wired for 20 amps. Placement matters as much as the rating, so review where to put the outlet for placement and cord reach. The full list of circuits by model is in electrical requirements by model.

The Adapter Option

When an electrician has already installed a standard household GFCI receptacle and the tub is otherwise ready to run, support has pointed customers to a plug adapter that converts a household outlet to a 20 amp T-blade female outlet. It is sold at hardware stores as a NEMA 5-15P to 5-20R adapter and is rated 15 amp to 20 amp at 125 volts. Ask your electrician to confirm the outlet is on a 20 amp line before using an adapter, since the plug is designed for a 20 amp receptacle and the 20 amp GFCI remains the correct receptacle.

Steps If the Plug Will Not Fit

  1. Confirm which cord it is: the T-blade plug is on the control box cord.
  2. Check the receptacle. A 20 amp receptacle has a sideways slot; a 15 amp receptacle does not.
  3. Have a licensed electrician verify the outlet is a 20 amp GFCI line.
  4. Replace the receptacle with a 20 amp GFCI, or use the T-blade adapter only after the electrician confirms the line is rated for 20 amps.
  5. Plug in both cords and test the tub. If the pump starts immediately, see why the pump turns on as soon as the tub is plugged in.

Common Questions

Was I shipped the wrong cord or a missing adapter?
No. The plug with one sideways blade is the correct 20 amp, 120 volt plug for the control box cord. It fits a 20 amp receptacle, which your electrician installs as part of the electrical work for the tub.
Can I just use a 15 amp GFCI outlet for the tub?
The T-blade plug will not physically fit a 15 amp receptacle, and the control box cord is designed for a 20 amp receptacle on a 20 amp line. Have your electrician install a 20 amp GFCI receptacle rather than forcing a workaround.
Is the 15 amp to 20 amp T-blade adapter safe to use?
Support has pointed customers to this adapter when a household GFCI is already in place. Use it only after a licensed electrician confirms the outlet is on a 20 amp line. The 20 amp GFCI receptacle remains the correct receptacle for the control box cord.
Does the T-blade plug connect to the heater somewhere?
The T-blade plug is the plug on the control box cord, and it plugs into the wall receptacle. The pump and heater are connected through the control box, so nothing is plugged into the heater itself. See which cord plugs in where for the layout.
Why does the tub need two separate outlets?
The tub has two cords, and both must be plugged in for everything to work, so two outlets are needed. How many GFCI circuits your model needs is listed in how many GFCI circuits does my walk-in tub need.
