One of the most common questions we receive is whether the Echo Go+™ is working correctly when it sounds different, produces different bubbles, leaks a little water from the bottom, or doesn't make the familiar "pop" when opening the lid.

The good news? Most of these behaviors are completely normal and are simply a result of how hydrogen water technology works.

This guide will help you understand what your Go+™ is doing, why it behaves the way it does, and when something is actually cause for concern.

How the Go+™ Generator Works

The generator located in the bottom of your Go+™ uses a process called electrolysis to create hydrogen-rich water.

Step 1: Electrolysis Begins

When a cycle starts, a small electrical current passes through the water.

Step 2: Hydrogen Production

The water molecules are separated into:

• Hydrogen Gas (H₂)
• Oxygen Gas (O₂)

Step 3: Hydrogen Dissolves Into Water

The hydrogen gas dissolves back into the water, creating hydrogen-rich water.

Step 4: Oxygen Is Released

The oxygen is safely expelled through the oxygen vent located on the bottom of the generator.

Your water remains water—it simply contains dissolved molecular hydrogen.

Why Your Go+™ May Look Different From Day to Day

Many customers expect every hydrogen cycle to look exactly the same. In reality, hydrogen production is affected by constantly changing environmental conditions. Factors that can influence what you see include:

• Water temperature
• Atmospheric pressure
• Humidity
• Altitude
• Water mineral content
• Dissolved oxygen levels
• Water volume
• Membrane hydration
• Frequency of use

Because these conditions change, it's normal for:

✔ Bubble patterns to vary

✔ Sounds to vary

✔ Pressure retention to vary

✔ Small leaking from the Oxygen Port to vary

✔ Bubble size and quantity to change

These differences do not necessarily indicate a problem with the bottle.

Understanding Bubble Production

Small Bubbles vs. Large Bubbles

The Go+™ naturally produces different bubble sizes of bubbles during hydrogenation.

• Fine Bubbles
  • These tiny bubbles indicate active hydrogen production and are commonly seen throughout the cycle.
• Larger Bubbles
  • Larger bubbles may collect around the electrode cage before releasing naturally.

Both types of bubbles are normal.

Why Bubble Production Changes

The number and size of bubbles you see are not a direct measurement of hydrogen concentration.

Bubble appearance can be influenced by:

• Water temperature
• Water composition
• Altitude
• Weather changes
• Frequency of use
• Membrane hydration

Even if the bubbles look different, your Go+™ can still be producing the same hydrogen concentration.

New Bottles & Bubble Performance

When first using your Go+™, it may take up to a week of regular use for the generator to fully stabilize and consistently build pressure.

During this break-in period, bubble appearance may vary.

If You See Fewer Bubbles

If your Go+™ has been sitting unused for a while or appears to be producing fewer bubbles than normal, the PEM membrane may need to be cleaned and/or rehydrated.

🔗 Cleaning & Maintenance Of Your Echo Go+™

Rehydrate ("Shock") the Generator

1. Heat one cup of filtered water in a ceramic or glass container.
2. Carefully pour the hot water into the Go+™.
3. Run a full 10-minute cycle.
4. Empty the bottle.
5. Refill with fresh filtered water.
6. Run another cycle.

This often restores normal bubble production and performance.

Constant Beeping

If your generator is constantly beeping, this could mean that your generator has water damage. 

Understanding the PEM Membrane

Inside the generator is a Proton Exchange Membrane (PEM).

This membrane is one of the most important components in the hydrogen generation process.

Think of it like a sponge—it performs best when properly hydrated.

Why Your Go+™ Arrives With Water Inside

Many customers notice a small amount of water inside the generator when they first receive their bottle.

This is completely intentional.

The distilled water is placed inside the generator to:

• Keep the PEM membrane hydrated
• Protect performance during storage
• Ensure optimal hydrogen production right out of the box

This water is not intended for consumption.

Why Hydration Matters

A properly hydrated membrane helps:

• Produce hydrogen efficiently
• Create consistent bubbles
• Improve pressure retention
• Support long-term durability

If the membrane becomes too dry, hydrogen production can become less consistent until it is rehydrated.

Understanding Sounds From the Generator

Your Go+™ may produce several sounds during operation.

These sounds are often a sign that the generator is actively working.

Normal Sounds Include:

✔ Humming

✔ Crackling

✔ Sizzling

✔ Light ticking

✔ Light hissing

✔ Soft whistling

✔ Brief pressure release sounds

These sounds can vary depending on:

• Water temperature
• Water mineral content
• Membrane hydration
• Bottle age
• Environmental conditions

Why Does the Generator Make Noise?

As electrolysis occurs:

• Electricity moves through the water
• Hydrogen and oxygen are produced
• Oxygen is vented from the generator

These processes naturally create sounds that may change from cycle to cycle.

Understanding the Oxygen Vent

Located on the bottom of the Go+™ is a small oxygen vent.

This vent serves an important purpose:

• Releases oxygen generated during electrolysis
• Helps maintain proper hydrogen production
• Prevents unwanted gases from remaining in the bottle

Water Dripping From the Bottom

Occasionally, you may notice moisture or small water droplets near the oxygen vent. This is usually normal.

Expected Moisture Purging

Small drips may occur because oxygen is expelled through the vent during operation.

Typical moisture ranges from:

• A few drops
• Up to approximately the size of the bottle base

This is generally not considered a leak. Simply set the Bottle Upright: Place the bottle upright to allow any trapped water to leak out.

Note: A leak from this area may occur if the bottle has been jostled and water has been trapped near the oxygen port. Once the water has drained, the bottle should stop leaking from this section. This type of leak will not affect the performance of your bottle. After draining, the bottle should function normally.  

Important

Always place your Go+™ on a water-safe surface and away from electronics or important documents while operating.

Tips to Avoid Leaks

• Avoid Over Filling; only fill to the fill line. Your bottle needs a little bit of room for pressurization.
  • Overfilling can cause water to spill or leak, especially during the hydrogen generation process.
• Proper Assembly of Generator and Lid; Tighten any loose components, such as the lid or the connection between the bottle and the base.
  • Verify that the bottle is securely attached to the generator base.
    • Align the Echo Go+™ logo with the charging port and twist left (counterclockwise) until the bottle is securely attached.
  • Check the lid seal for proper placement and condition.
    • Make sure the lid is screwed on tightly but not over-tightened, as this could damage the seal.
• Check the Seals; Ensure all silicone seals are correctly installed and in good condition.
  • Verify that only one set of seals is installed.
  • Replace any worn or damaged seals as soon as possible. Extra seals are provided for convenience.

Steps to Address abnormal Leaks

• Inspect the bottle, generator base, and lid for any cracks or damage.
• Replace any damaged parts as needed.
• 🔗 Cleaning & Maintenance Of Your Echo Go+™
  • Regularly clean the seals and the areas around them to prevent buildup that can affect the seals' performance.
  • Follow the cleaning instructions provided in the manual for proper maintenance.

Understanding the Lid & Pressure Release Valve

The lid contains a pressure-release valve designed to safely release pressure during and after hydrogenation.

Why Does the Bottle Sometimes "Pop" When Opened?

You may hear a gentle "pop" when opening the lid. This is simply pressure being released and is similar to opening a carbonated beverage. This is normal.

Why Doesn't My Bottle Pop Anymore?

Many customers become concerned when the pressure-release sound disappears. In most cases, this is actually a sign that the valve has become more efficient. As the valve breaks in:

• Pressure may release more smoothly
• The popping sound may become quieter
• The sound may disappear entirely

This does not affect hydrogen production.

Newer Go+™ Pressure Valve Design

Newer Go+™ models feature an improved pressure-release system.

Because these valves are more efficient, some customers may never hear a pressure-release sound at all.

Whether your bottle pops loudly, quietly, or not at all, hydrogen production remains the same.

Normal Go+™ Behaviors

The following behaviors are generally considered normal:

✔ Fine hydrogen bubbles

✔ Larger bubbles releasing periodically

✔ Pressure buildup during operation

✔ Pressure release when opening

✔ Humming, hissing, crackling, or sizzling sounds

✔ Small amounts of moisture from the oxygen vent

✔ Changes in bubble appearance

✔ Changes in sound from cycle to cycle

✔ Slight warmth during operation

✔ Variations in pressure retention

Most of these are signs that your Go+™ is actively producing hydrogen and functioning properly.

When Should I Be Concerned?

You may need troubleshooting or support if:

❌ The bottle produces no bubbles several cycles after cleaning and rehydrating

❌ The generator will not start a cycle

❌ Excessive leaking occurs beyond normal moisture purging

❌ The bottle will not charge

❌ The oxygen vent becomes blocked
