What to Do If Your JBL PartyBox 310 Gets Wet

What You'll Need

  • Soft, absorbent cloths (microfiber is ideal)
  • A dry, well-ventilated area
  • Silica gel packets or a large container of uncooked rice (Optional)
  • Patience (this is the most critical tool!)

First Aid Steps

  1. POWER OFF IMMEDIATELY: This is the most critical step. If the speaker is on, turn it off. If it is plugged into the wall, unplug it immediately. Do not attempt to turn it on to see if it still works. This prevents short circuits.
  2. Dry the Exterior: Use soft, absorbent cloths to thoroughly dry the entire exterior of the speaker. Pay close attention to seams, speaker grilles, and the control panel.
  3. Open the Port Cover: Open the rear protective cover for the input/output ports. This will allow trapped water to escape and improve air circulation inside the unit.
  4. Position for Draining: Gently place the speaker on its side on top of a dry towel, with the open port panel facing down. This uses gravity to help any water drain out. You can also carefully place it face down on a soft, thick towel.
  5. Let It Dry (Wait!): Move the speaker to a dry, well-ventilated area. Let it air dry for a minimum of 48 to 72 hours. Do not rush this process. Patience is essential for letting internal components dry out.
  6. Use Desiccants (Optional): If you have a large plastic container, you can place the speaker inside with numerous silica gel packets (the kind found in new shoe boxes or electronics). Uncooked rice can also be used as a last resort to help absorb moisture, but direct air drying is often more effective.
  7. Do NOT Use Heat: Never use a hairdryer, heater, or oven to try and speed up the drying process. High heat can warp plastic components and damage sensitive electronics and battery cells.
  8. Test After Thorough Drying: After at least 2-3 days, you can attempt to plug in and power on the speaker. If it works, test all functions (Bluetooth, lights, inputs). If it does not power on or behaves erratically (crackling sounds, strange smells), unplug it immediately.
  9. Seek Professional Repair: If the speaker does not work correctly after drying, it needs professional service. Water leaves behind mineral deposits that cause corrosion over time. A technician will need to disassemble the speaker and clean the internal circuit boards to prevent long-term failure.

Water Damage FAQs

Is the JBL PartyBox 310 waterproof?

No, it is not waterproof. The PartyBox 310 has an IPX4 rating, which means it is splash-proof. It can handle light splashes of water from any direction, like rain or poolside splashes, but it cannot be submerged or exposed to heavy jets of water.

I spilled a drink on it and it turned off. What does that mean?

It likely means the liquid caused an immediate short circuit, which may have triggered a protective cutoff or caused damage. Do not try to turn it back on. Follow the drying steps immediately and be prepared to seek professional service, as sugary or alcoholic drinks are very corrosive.

Can I use a hairdryer on a cool setting?

While cool air is better than hot air, it is generally not recommended. A strong, concentrated airflow can push water deeper into the speaker's internal components. Natural air drying in a well-ventilated room is the safest method.

It works, but now the sound is muffled or crackly. Can I fix this?

This could be due to moisture still trapped in the speaker cones or a sign of corrosion on the amplifier board. Let it dry for another 24 hours. If the problem persists, the speaker drivers or electronics have been damaged and will need professional inspection and repair.

Why is professional cleaning necessary if it seems to work fine?

Even after the water evaporates, it leaves behind minerals and contaminants. Over weeks or months, these deposits can cause corrosion on the circuit boards, leading to eventual failure. A professional cleaning with appropriate solutions is the only way to prevent this long-term damage.
