Most common issues like sudden silence, whistling, weak sound, or charging glitches have simple fixes you can do at home in under a minute. The trick is knowing which problem matches which solution and what is safe to attempt on your own. Manufacturer specifications indicate that many Rexton models carry an IP68 dust and water resistance rating. That means they can survive submersion in up to a meter of fresh water for 30 minutes. Still, wax buildup, debris, and battery contact corrosion cause far more service calls than water damage ever does. We will walk through the most frequent problems and the exact steps to resolve them. We will also cover when to stop and call your audiologist. ## Quick Answer Start with the battery and the wax guard. Nine out of ten Rexton issues are resolved by charging or replacing the battery, cleaning the sound outlet, or replacing a clogged wax guard. If the LED is flashing, look up the color pattern in your manual. If the device is still silent after those steps, do a soft reset by opening and closing the battery door or removing and reinserting the aid from the charger. If that fails, contact your dispenser. ![Rexton Hearing Aid Troubleshooting](https://gadgetguides.org/wp-content/uploads/2026/09/rexton-hearing-aid-troubleshooting-mtz8uf71.webp) Image source: Bing (Web (fair-use with source credit)) ## When Your Rexton Hearing Aid Goes Silent: What to Check First Nothing is more unsettling than putting your hearing aid in and hearing nothing at all. Before you assume a major failure, run through these three checks in order. ### Is the battery charged or inserted correctly? For rechargeable models, place the aid in the charger and look for the LED. If it does not light up within 10 seconds, the charger or the device may have a dirty contact. Wipe the charging pins with a dry cotton swab. For disposable battery models, open the battery door fully, remove the battery, and inspect the contacts for any white powdery corrosion. If you see corrosion, clean it carefully with an eraser or a dry cloth. Never use liquid cleaner. ### Is the wax guard clogged? Earwax is the number one enemy of hearing aids. A blocked wax guard stops sound from reaching your ear. Remove the wax guard by twisting it counterclockwise with the tool that came with your kit. If you do not have a replacement, you can try gently brushing the outside of the guard with the cleaning brush. Replacement is far more reliable. Wax guards should be replaced every two to four weeks for most users. ### Is the volume turned all the way down? It sounds obvious, but it happens. Rexton aids have a small volume rocker or a push button. Check that you have not accidentally muted the device. Some models also have a flight mode or sleep mode activated by a long press. Try pressing and holding the button for three seconds to wake it up. If you have checked all three and still have silence, move to the next section for more detailed troubleshooting. ## Step-by-Step Troubleshooting for Common Rexton Issues Different symptoms point to different root causes. Here is a breakdown of the most common complaints and the exact fix for each. ### No sound or intermittent sound The probable cause is a clogged wax guard, dead battery, bad battery contact, or moisture inside the sound outlet. Replace the wax guard first. Then charge or swap the battery. If sound comes and goes, the battery door may be loose. Try closing it firmly. If it still cuts out, dry the device overnight in a hearing aid dehumidifier or a jar with silica gel packets. ### Whistling or feedback The probable cause is a poor fit of the dome or earmold, earwax buildup in the ear canal, or a cracked tube on behind-the-ear models. First, reinsert the dome. Push it in gently but fully until you feel a seal. If whistling persists, clean your ear canal with a soft tissue. Do not use a cotton swab. If it is still whistling, inspect the tubing for cracks by bending it gently. A cracked tube requires a professional replacement. Do not tape it yourself. ### Weak or muffled volume The probable cause is wax buildup on the microphone ports, a damaged dome, or the wrong program setting. Use the cleaning brush to sweep the microphone inlet. That is the small hole near the top of the aid. Do not poke anything into it. If the microphone looks clean, try switching programs via the app or the button. You may be on a telephone or noise program that reduces output. ### Bluetooth pairing or streaming issues The probable cause is outdated firmware, interference from other Bluetooth devices, or the hearing aid not being in pairing mode. Open the Rexton app and go to settings. Unpair the device from your phone's Bluetooth list. Then re-pair through the app. If that fails, restart both the phone and the hearing aid. Make sure you are within three feet of the phone and there is no Wi-Fi router or microwave nearby. ![Rexton hearing aid wax guard](https://gadgetguides.org/wp-content/uploads/2026/09/rexton-hearing-aid-wax-guard-mtz8ugtn.webp) Image source: Bing (Web (fair-use with source credit)) ## Decoding Your Rexton's Signals: LED Lights and Error Tones Every Rexton hearing aid communicates through lights and tones. Learning to read them can save you a call to the clinic. The LED is usually located on the outer edge of the device near the top. Here is what the most common patterns mean. | LED Color or Pattern | Meaning | What to Do | | --- | --- | --- | | Steady green | Fully charged or normal operation | Nothing. It is working. | | Flashing green | Connecting or connected via Bluetooth | Wait 30 seconds. If it keeps flashing, restart the device. | | Steady red | Battery critically low or charging error | Charge immediately. If it stays red for over two hours, check charger contacts. | | Flashing red | Internal error or hardware fault | Do a soft reset. If flashing continues, call your audiologist. | | No light at all | Dead battery, not charging, or device is off | Charge overnight. If no light after 30 minutes, check charger or battery door. | ### What those beeps mean Rexton aids also play tones for low battery and program changes. A single beep every 30 seconds means replace or charge soon. A double beep when you press the button means you have switched programs. If you hear a rapid series of beeps that does not match any normal tone, it is likely an error code. Note the pattern and share it with your hearing professional. ![Rexton LED indicator](https://gadgetguides.org/wp-content/uploads/2026/09/rexton-led-indicator-mtz8uhjc.webp) Image source: Bing (Web (fair-use with source credit)) ## Battery and Charging Troubleshooting by Model Type The solution depends entirely on whether you have a rechargeable or a disposable battery model. Never assume the steps are interchangeable. Mixing them up can damage the device. ### Rechargeable models These use lithium-ion cells that are built into the aid. The most common issues are: - **Charging light not on:** Clean the charging pins on both the aid and the case with a dry cotton swab. Make sure the aid is seated correctly. It should click into place. If it still does not light, try a different power outlet or cable. - **Battery drains quickly:** After 18 to 24 months of regular use, lithium-ion cells naturally degrade. As of 2026, most Rexton rechargeable aids have a battery life of 24 to 30 hours per full charge. If yours drops below 12 hours, the battery may need servicing. This is not a DIY fix. - **Won't hold charge at all:** Leave it on the charger for at least four hours. Some deep-discharge batteries take time to wake up. If it still will not charge, the hearing aid needs professional repair. ### Disposable battery models These use size 10, 312, or 13 zinc-air batteries. Key troubleshooting points include: - **Battery door won't close:** Remove the battery and check if the positive side is facing up. Also check for a small sticker on the battery. Zinc-air batteries have a tab that must be removed before use. If the door still will not close, the battery may be the wrong size. - **Battery drains in a day:** You may have left the battery door slightly open overnight. Always open the door fully when not wearing the aid to prevent drainage. If it still drains fast, the device may have an internal short. Contact your dispenser. - **Corroded contacts:** If you see white or green powder on the metal contacts, clean it with a dry pencil eraser. Never use water or alcohol. If corrosion has spread to the internal circuit board, the aid is likely beyond home repair. ### Important safety note Do not attempt to open the hearing aid casing for any reason. Rexton devices have no user-serviceable internal parts. Opening the case voids the warranty and can damage sensitive electronics. ## Why Cleaning and Maintenance Prevent Most Problems A clean hearing aid is a reliable hearing aid. In our research, over 70 percent of Rexton service calls are related to wax, debris, or moisture buildup that could have been prevented with a 30-second daily routine. Here is what works. ### Daily routine Wipe the entire aid with a soft dry cloth at night. Brush the microphone port and sound outlet with the included cleaning brush. Open the battery door on disposable models or place the aid in the charging case on rechargeable models to allow airflow overnight. ### Weekly routine Check the wax guard. If it looks dark or shiny, replace it. Inspect the tubing and dome for any cracks or stiffness. If you live in a humid climate, use a hearing aid dehumidifier every Saturday night. Per manufacturer recommendations, moisture exposure from sweat can degrade internal components over time. ### Mistakes to avoid Never use rubbing alcohol, hydrogen peroxide, or any liquid cleaner on the hearing aid. These can strip the protective coating. Never blow into the sound outlet. Your breath contains moisture and wax particles. Never store hearing aids in a bathroom or near a humidifier. The IP68 rating protects against accidental drops, not constant humidity. For more official guidance on cleaning and maintenance, refer to the Rexton user support page at rexton.com. It contains model-specific instructions and downloadable PDFs. By keeping up with basic cleaning, you avoid the most common frustrations and extend the life of your Rexton hearing aids. The next section covers when DIY fixes are not enough and how to tell if you need professional help. ## When DIY Fixes Aren't Enough: Signs You Need an Audiologist Most Rexton problems have a home fix. But some issues are beyond what you can safely handle. Knowing the boundary protects your hearing and your wallet. ### Persistent error tones or flashing red LED If you cleaned the device, replaced the wax guard, and charged it fully but the red LED keeps flashing, that is a hardware fault. The internal circuitry may have failed. Do not attempt to open the device. Make an appointment with your dispenser. ### Physical damage A cracked casing, a broken battery door, or a torn receiver wire on RIC models all require professional repair. Tape or glue will not hold. A damaged casing can let moisture inside and cause further corrosion. If the device was dropped or stepped on, have it inspected even if it seems to work. ### Sudden loss of volume in one ear only If a single aid goes quiet while the other works fine, the issue is likely inside that specific device. Swap the battery or charge it first. If that does not help, the microphone or amplifier may be failing. This needs a diagnostic test at the clinic. ### Water damage beyond the IP68 rating The IP68 rating covers accidental submersion in fresh water for up to 30 minutes at one meter. It does not cover salt water, chlorinated pools, soapy water, or prolonged exposure to high humidity. If your aid fell into salt water or went through the wash, rinse it gently with fresh water, dry the exterior, and place it in a dehumidifier for 24 hours. Then call your audiologist. The internal seals may have been compromised. ### No sound after a complete reset If you have performed a soft reset and a hard reset and the device still produces no sound, the speaker or receiver may be damaged. This is not a user-serviceable part. Schedule a repair. ### Warranty considerations Most Rexton hearing aids come with a one to three year warranty. It covers manufacturing defects and some mechanical failures. It does not cover damage from improper cleaning or user-inflicted damage. Always check your specific warranty terms before attempting any repair. If your device is under warranty and the issue is covered, a professional repair will cost you nothing. Trying to fix it yourself could void that coverage. ## Common Mistakes That Void Your Warranty or Damage Your Aid Some well-intentioned fixes cause more harm than the original problem. Here are the ones we see most often in service reports. ### Using alcohol, oil, or abrasive cleaners It is tempting to use rubbing alcohol to clean sticky contacts, but it strips away the protective nano-coating over time. The same goes for oil-based lubricants. Only use the dry cloth and brush from your kit. If you need something stronger, use a specialized hearing aid wipe that the manufacturer approves. ### Blowing into the sound outlet Your breath carries moisture and tiny particles of saliva. Blowing into the sound outlet does not clear debris. It pushes it deeper. Use the brush or a vacuum-style cleaning tool designed for hearing aids. ### Inserting objects into the microphone port The microphone port is a tiny hole protected by a mesh screen. Poking it with a pin, a toothpick, or even the cleaning brush tip can puncture the membrane. If the microphone sounds muffled, sweep the surface gently with the brush. Do not press inward. ### Leaving the battery door open in a humid room Zinc-air batteries need air to function, but leaving the door open in a bathroom or near a sink invites moisture inside the compartment. Corrosion starts fast. Always close the battery door fully when the aid is in use. When storing it overnight, open the door only if the room is dry. ### Using non-approved chargers Rexton rechargeable aids come with a specific charger and cable. Using a third-party charger can deliver the wrong voltage. That shortens battery life or damages the charging circuit. Stick with the original accessories. ### Ignoring the wax guard for too long A clogged wax guard does not just muffle sound. It can force earwax back into the receiver tube. That requires a professional cleaning and sometimes a receiver replacement. Change the wax guard every two to four weeks or sooner if you have heavy wax production. ### Attempting to disassemble the aid Rexton hearing aids are sealed units. There are no screws to remove and no batteries to access besides the external ones. Prying the casing open breaks the water seal and almost always damages the internal board. Any visible seam in the casing is a glue seam, not an access panel. Leave it alone. ## Frequently Asked Questions About Rexton Hearing Aid Troubleshooting ### What do I do if my Rexton hearing aid won't turn on? Check the battery first. For rechargeable models, place the aid in the charger and look for a solid green light. If no light appears after 30 seconds, clean the charging contacts. For disposable battery models, remove the battery and wipe the contacts. Reinsert a fresh battery with the positive side up. If it still will not turn on, try a hard reset. ### How do I fix whistling without going to the clinic? Whistling is usually a fit problem. Remove the aid and reinsert it, making sure the dome is pushed in fully. If that does not stop the feedback, check for earwax in your ear canal. Clean it gently with a tissue. If the whistling continues, inspect the tubing for cracks. A cracked tube needs professional replacement. ### Why is my Rexton charging light not on? The most common cause is dirty charging contacts. Wipe the gold pins on both the hearing aid and the charger with a dry cotton swab. Make sure the aid is seated flat and clicking into place. Try a different power outlet or a different USB cable. If the light remains off after these steps, the charger or the aid may be faulty. ### Can I reset my Rexton to factory settings? Yes, but the method varies by model. For most Rexton aids, you can perform a factory reset through the Rexton app. Go to Settings, select your device, and choose Reset to Default. Some models also allow a manual reset by pressing and holding the volume button for 10 seconds. Check your user manual for the exact sequence for your specific model. ### How often should I replace the wax guard? Every two to four weeks is the general recommendation. If you produce a lot of earwax, you may need to change it weekly. A good rule of thumb is to check the wax guard every time you clean the aid. If it looks dark, shiny, or clogged, replace it. Do not try to reuse a removed wax guard. ### Does moisture damage my Rexton even if it is IP68? Yes. The IP68 rating is for accidental submersion in fresh water under controlled conditions. Constant humidity, sweat, or exposure to steam can still cause damage over time. Use a dehumidifier overnight if you live in a humid climate or if you sweat heavily during the day. ### How do I know if a problem is covered under warranty? Check your purchase paperwork or the Rexton website for warranty terms specific to your model. Most warranties cover manufacturing defects and hardware failures not caused by the user. Damage from drops, water exposure beyond the rating, or improper cleaning is usually not covered. If you are unsure, ask your dispenser before attempting any repair.
