H620 flashes pink 10 times when turned on. I have charged the unit and had a green indicator, Any idea what the flashing pink means when turned on.

If it is supposed to go green then the battery is not being fully charged. Unit is under warranty and now is the time to have matter addressed.

I agree that the pictographs are not very helpful. You probably have one of the new chargers. I have an old one, which is a little easier to figure out.

From top to bottom

1. The flashing green light with the electric plug indicates that the unit is plugged in and ready to go.
2. The flashing red little fan means that the battery is too warm so it is just cooling it and not charging it at that moment.
3. The solid red empty battery outline means that it is charging but hasn't got very far, less than 80% full.
4. The mostly full battery outline with both solid red and green lights at the same time means it is 80% full or more
5. The full battery outline and solid green with the musical notes means it is full up.
6. The broken battery outline with flashing red and green means you've got a broken battery.
7. The yellow light with the wrench means the charger is "conditioning" the battery, whatever that means.
8. The yellow light with the fan means "cooling abnormality."

Hope this helps

A red light indicates the charger is charging the battery, an amber light means it has switched from fast rate charging to trickle to keep the battery topped off, and green would mean the battery is completely charged. But don't be fooled waiting for green, many times the charger will only be on green for a moment before changing to amber and keeping the battery topped off.

Flashing can be a sign of a problem on some chargers.

A rapid flashing red can on some chargers indicate a bad or shorted battery, or a bad battery contact in the charger itself. If in question, try a different battery on the charger or compare with another charger to determine if the blinking is normal.

Best regards.

according to manualslib type site for the wg540, solid red means charging for the wa3840 and wa3838. After 30 minutes if battery has not reached 10 volts (of 18), the red will begin flashing meaning defective.
Just green? Ready to go. Green flashing? Overheat.
Tangent; sometimes a discharged battery needs a little coaxing - have to get a little voltage into the battery for charger to try to charge. Different company, electric drill. I plead ignorance if this applies for the 3840 since they mention the half an hour time.

The Flashing lights indicate several different things. 1 flashing red light means its time to charge your unit. if it is still flashing after charging then you will more than likely need to change the battery. A flashing red and green light means that the unit is overheating which could happen if the filters need to be washed, or that there is a blockage or if your machine has been left in direct sunlight. Allow 1 hour for machine to cool down. 3 flashing lights indicated that the pre-filter has been put on incorrectly. I hope this helps. If you do decide to wash your filter dont use any type of soap it is not needed and allow fiter to dry for atleast 24 hours. putting a wet or damp filter in will damage your machine.

Red light normally means that the battery needs charging. The green flashing light can mean the battery is charging or has charged, and the same with the solid green light. Green in this case is good.

Charge the unit overnight and see what the indicator state is. It should not take more than 8 hours of charging for a Li-ion battery. Once you know what the full state light looks at, then you can tell what the charging indicator looks like.

In all cases, ensure you are using the proper charger with the unit.

According to the owners manual for these swimming pool lights, this is what each colored indicator means. Hope this helps.


Solid green
The battery pack is fully charged.
Slow flashing green
The battery pack is almost fully charged.
Slow flashing yellow
The battery pack is half charged.
Medium flashing yellow
The battery pack is less than half charged.
Fast flashing yellow
The battery pack has almost no charge.
Fast flashing red
A charging error has occurred and the light should be unplugged and then plugged back in. If the Fast Flashing Red persists after several attempts, the battery condition is questionable.



Also in the trouble shooting guide, it mentions this:


Problem: Red Indicator Light Is Flashing While Charging

Solution:
A red flashing indicator light when charging indicates a selftest
error condition. Unplug the product and plug it in again.
Try this several times; if the indicator light continues to flash
red, unplug the GlowBuoy and take it to an authorized service
depot.

What does indicator light mean?

• Steady red light: Battery is charging.
• Steady green light: Battery is fully charged.
• Flashing red light: Battery needs charging.
• Flashing green light: The music receiver is switched on.
• Flashing red/green light: The music receiver is available to be added to your phone.

A 2-2 code on that unit means over current shutdown. 95% of the time that code indicates defective convergence output IC's.

Ok the lightning bolt is your power indicator: solid green-charging, Flashing green-fully charged, flashing red-low battery, flashing red three times the once green-bad battery. the "trash can" looking one is your hard drive activity indicator it will flash while your hard drive is reading and writing.
