It beeps and shows 4000

4000 is the safety limit. The machine beeps and stops when the water is carrying too much electricity — that’s it protecting you. Let’s find why in a couple of taps.

Has this foot bath worked for you before?

Your array may be worn out

If it ran fine before and now beeps non-stop, the most likely reason is simple: the array — the metal coil that sits in the water — wears out with use. Each one lasts for a limited number of sessions (about 20–30), then it stops working.

Still have the second array from your kit? Try that one first: unplug the old one, plug in the unused spare, and test it with plain water.

Does it run normally with the spare array?

Time for a fresh array

That confirms it — your first array is simply used up, which is completely normal with regular use. Drop in a fresh array and you’re back to your usual sessions.

Let’s check your water

When it beeps at 4000, the water is carrying too much electricity. This is almost always down to the type of water you’re using — some water naturally carries far more electricity than others — and not the machine itself.

Do you have a water softener or water-treatment system at home?

Softened water is the cause

A water softener works by adding salt to your water. So your water is already “salty” to the machine — and that alone maxes it out at 4000, even when you add no salt yourself. Nothing is broken; it’s just the water.

• Fill the tub with plain water from a tap that skips the softener — an outdoor garden faucet usually works. Start with no salt.
• No unsoftened tap nearby? Mix half your water with half distilled/bottled water.
• If the reading then drops low (around 1800) or the water stays pale, add a little Epsom salt, a scoop at a time, until it settles.

Your water is likely hard / mineral-rich

Water that’s high in minerals carries a lot of electricity on its own — enough to trip the alarm. Here’s what to do, depending on whether you added salt:

If you added the recommended salt

• Empty the tub and refill — but this time add no salt at all, since your water already carries plenty on its own.
• Still beeping with no salt? Your water is simply too mineral-rich — mix it 50% with 50% distilled/bottled water and try again.

If you didn’t add any salt

• Your tap water is naturally very mineral-rich, which acts just like salt. Mix it half-and-half with distilled/bottled water and run with no salt.
• Still beeping after trying the spare array too? Tap below and we’ll help.

Water stays pale / no color

Look at the array in the water — do you see bubbles coming out?

It just needs a little calibration

Good news — bubbles mean your machine is working. Pale water simply means it isn’t carrying enough electricity, usually because your water is soft, filtered, or very pure (RO).

• If you use filtered or RO water, switch to regular tap water first.
• Add Epsom salt a little at a time to bring the reading up to a healthy level.
• Still pale? Epsom isn’t always strong enough to bring out the color — add a tiny pinch of table salt to kick-start it (just a pinch; see the FAQ).

Let’s close the circuit

No bubbles means the circuit isn’t completing.

• Make sure the array’s plug is pushed all the way into the base.
• Wet the skin under the wristband’s metal plate (or add lotion) — dry skin blocks the current.
• Try the spare array to rule out a broken coil.

The wristband stings

This isn’t a burn. Your body is part of the circuit, and if the skin under the metal plate is dry, the current is forced through tiny pores and causes a pinch.

• Turn the machine off.
• Apply lotion, gel, or water under the metal plate.
• Tighten the strap — the sting stops right away.

Safety & FAQ

Can I use this with a pacemaker?
No. Anyone with a pacemaker, an organ implant, or epilepsy should avoid electromagnetic devices, as the circuit can interfere with medical equipment.

Epsom salt or table salt?
Use Epsom salt for your sessions and to raise the reading. A tiny pinch of table salt can be used only to bring out the color when the water stays pale — but don’t use it regularly, as it wears the array out faster.

How the detox works

The brown color is normal — it’s just the metal array reacting with the minerals in the water, even before your feet go in. We’re upfront about that.

The real work is the ionic field (the bubbles). As you soak, your body takes in negative ions that bind to and neutralize positively charged toxins inside you.

Some debris is pulled into the basin, but the main cleanse happens inside you: the ionic exchange stimulates your lymphatic system, which flushes toxins over the next 24–48 hours.
