If your hearing aids have gone quiet, keep cutting out, refuse to charge or won't pair with your phone, take a breath. Thousands of people search for Signia hearing aids troubleshooting help every month, and most problems are small and fixable at home. A blocked wax guard, a dirty charging contact or a Bluetooth glitch is often all it takes.
This guide covers the most common faults on Signia hearing aids, including rechargeable models, RIC styles and the latest IX platform devices. Follow the steps in order and you can usually get your Signia hearing aid working again in under ten minutes.
Why Do Signia Hearing Aids Stop Working?
Hearing aids are small electronic devices worn in a warm, moist environment, so some wear is normal. The usual causes are:
- Earwax or debris blocking the wax guard, receiver or microphone openings
- A flat battery or a charger with dirty contacts
- Moisture from sweat, rain, showers or humidity
- A loose, worn or wrongly sized dome or earmold
- A Bluetooth or Signia app glitch after a phone update
- Outdated software on your phone or hearing aids
Once you know the likely cause, the fix is much quicker.
Quick 60-Second Checklist Before You Start
- Check that both hearing aids are switched on and the volume has not been lowered.
- Place them in the charger for a few minutes to rule out a low battery.
- Wipe them with a dry, soft cloth.
- Make sure the dome or earmold is seated properly in your ear.
- Restart the hearing aids (see Fix 7).
If the problem continues, move on to the specific fix below.
Fix 1: Signia Hearing Aid No Sound or Weak Sound
A Signia hearing aid with no sound is the most common complaint, and usually the easiest to solve.
- Replace the wax guard. The small filter at the receiver tip blocks wax from entering. When it clogs, sound becomes weak or disappears. Use the tool in your wax guard pack.
- Check the dome or earmold. Make sure the opening is clear and the piece is seated correctly.
- Clean the microphone ports. Brush gently with the cleaning brush. Never use water, alcohol wipes or sharp objects.
- Check the charge. Put both aids in the charger and confirm the indicator light responds.
- Check your ears. Sometimes the hearing aid is fine and wax in the ear canal is muffling sound. A hearing professional can check this for you.
Fix 2: Signia Hearing Aid Not Charging or Charger Not Working
Charging faults are common on rechargeable models such as the Signia Pure Charge&Go IX. Try this:
- Make sure the charger is firmly plugged into a working outlet. Try a different cable or adapter.
- Wipe the charging contacts on the hearing aids and the charging case with a dry, lint-free cloth. Dust and skin oils are a surprisingly common cause.
- Remove the hearing aids, wait about 30 seconds, then place them back so they sit snugly in the slots.
- Check the charger's indicator lights. Light patterns vary by model, so refer to your user guide.
- Avoid charging in very hot or very cold rooms, as extreme temperatures can interrupt charging.
- If you use a portable charging case, make sure the case itself has enough charge.
If the lights still show a fault after cleaning and re-seating, the battery or charger may need a professional check.
Fix 3: Signia Hearing Aid Not Connecting to Bluetooth or the Signia App
Bluetooth problems are more common now that many people stream calls, music and TV audio directly to their hearing aids. Here is the fix:
- Turn Bluetooth off and on again on your phone.
- Restart both hearing aids by placing them in the charger and taking them out again.
- Open your phone's Bluetooth settings and remove (forget) the hearing aids.
- On an iPhone, go to Settings, then Accessibility, then Hearing Devices to pair again. On Android, pair through Bluetooth settings or follow the in-app pairing steps.
- Update the Signia app and your phone's operating system.
- Keep your phone within a metre or so of your hearing aids while pairing.
If the Signia app is not connecting even after re-pairing, ask your hearing professional whether your hearing aids need a firmware update.

Fix 4: Signia Hearing Aid Whistling or Feedback
A whistling Signia hearing aid means sound is escaping from the ear and being picked up again by the microphone.
- Remove the hearing aid and reinsert it so the dome sits fully in the canal.
- Check the dome for splits or stretching and replace it if worn.
- Check for wax in the ear, which can reflect sound and cause feedback.
- Lower the volume slightly if whistling happens only when you hug someone or wear a hat.
- If it keeps happening, you may need a different dome size or a custom earmold.
Persistent feedback after these steps is usually a fitting issue rather than a fault.
Fix 5: Only One Signia Hearing Aid Working or Cutting Out
When one Signia hearing aid is not working, compare it with the good side:
- Swap the wax guards and domes between left and right. If the problem moves sides, it is a blockage, not a fault.
- Charge both hearing aids fully and restart them together.
- Dry the affected one overnight in a drying kit if you suspect moisture.
- On RIC models, check the thin receiver wire for damage or kinks.
- Intermittent cutting out after cleaning and drying usually points to a worn receiver or moisture damage that needs a repair check.
Fix 6: Distorted, Muffled or Crackly Sound
Distortion is often mistaken for worsening hearing when it is really a maintenance issue.
- Moisture: Wipe the aids and use a drying kit or dehumidifier overnight.
- Debris: Clean the microphone openings and replace the wax guard.
- Low battery: A dying battery can cause crackling before the aid shuts off.
- Streaming interference: If it only happens during streaming, re-pair your phone and move away from other Bluetooth devices.
If the sound is still poor with a clean, dry, fully charged device, the programming may need adjusting.
Fix 7: Signia Hearing Aid Won't Turn On or Needs a Reset
To reset Signia hearing aids and clear minor glitches:
- Place both hearing aids in the charger and leave them for a minute.
- Take them out and wait for the start-up sound or indicator.
- If nothing happens, clean the contacts and try another power source.
- Leave them charging longer to rule out a deeply drained battery.
Steps differ slightly between models, so check your user guide as well.
Fix 8: Signia Hearing Aid Battery Draining Fast
If battery life has dropped, consider these causes:
- Streaming calls, music and TV audio uses more power than normal listening.
- Noisy environments make advanced processing work harder.
- Rechargeable batteries gradually lose capacity after a couple of years of daily use. This is normal.
- Dirty contacts can stop a full charge.
- Extreme heat or cold temporarily shortens battery performance.
Charging every night keeps your hearing aids ready for a full day.
Troubleshooting Signia IX, Pure Charge&Go and RIC Models
The steps above apply across the current range, with a few model notes:
- Signia IX hearing aids: These use advanced processing, so heavy streaming and very noisy settings can draw more power. Keep the Signia app and phone software updated and charge fully each night.
- Signia Pure Charge&Go IX: If it won't charge, clean the contacts weekly and make sure the aids click into the case properly.
- Signia RIC hearing aids: The receiver sits deep in the ear and collects wax, so check the receiver wire and wax guard first.

Daily Signia Care Routine to Prevent Problems
- Wipe your hearing aids every evening with a soft, dry cloth.
- Brush microphone openings gently once a week.
- Replace wax guards regularly, or sooner if sound drops.
- Store them in the charger or a dry case overnight, never in the bathroom.
- Keep them away from hairspray, water and extreme heat.
- Update the Signia app and your phone regularly.
Cleaning brushes, wax guards and drying products make this routine easy. Browse our hearing aid accessories to keep your devices in top shape.
When to See a Hearing Professional
Contact an audiologist if:
- The problem persists after cleaning, resetting and re-pairing
- You notice a sudden, unexplained drop in your hearing
- There is visible damage to the hearing aid, receiver wire or charger
- Sound still seems wrong even with a clean, dry, fully charged device
- You feel dizziness, pain or discharge from the ear (seek medical care promptly)
If the problem is about settings, such as sounds that feel too loud, too soft or unclear, you may not need a clinic visit. You can book professional remote hearing aid programming and have your settings adjusted online.

Frequently Asked Questions
Why is my Signia hearing aid not working?
The most common causes are a blocked wax guard, a low charge, moisture or a poorly fitted dome. Replace the wax guard first, then check charging.
How do I reset my Signia hearing aids?
For most rechargeable models, place them in the charger and remove them again to restart. Check your user guide for exact steps for your model.
Why won't my Signia hearing aids connect to my iPhone or Android?
