Updated: Nov 11

Just like any other electronic device, your hearing aids need good maintenance and care and eventually, they may need repair. Read this article to see what needs to be done, and when and how to extend the life of your hearing aids.

First and foremost I need to clarify that there is a fine line between the hearing aids that need repair and the hearing aids that require cleaning, or those which need reprogramming and adjustment. I have separated the symptoms of a faulty hearing aid into 3 different groups. Please continue reading.


Group A (setting and fitting optimisation)

If you experience any of the following with your hearing aids then you need to seek help from your audiologist to reprogram or adjust the settings of your hearing aids. Your hearing aids might need setting and fitting optimisation.

  • The hearing aid is uncomfortable or painful

  • The hearing aid does not stay in/on your ear

  • The hearing aid whistles

  • Your ears feel plugged up

  • Your voice sounds strange and very loud (or boomy)

  • You can’t hear the conversation in noisy places like restaurants

  • You can’t hear well over the telephone

  • Sounds around you like paper rustling or water running are too loud

  • The hearing aid is not being inserted properly

  • Earmold doesn’t fit right (falling out, moving, hard to insert, hurts, noise while chewing, plugging, popping).

  • The ear canal is plugged with earwax

  • Hearing has changed, you need a fresh hearing test and a reprogramming





Group B (training)

Believe it or not, a big part of what users perceive as a faulty hearing aid may be fixed with a bit of cleaning and caring.

  • The battery is dead or inserted incorrectly

  • The wax guard is plugged

  • The microphone is plugged

  • The speaker wire is damaged

  • The tubing is old and stiffened or possibly cracked

  • The tubing has moisture/liquid inside it

  • The vent is plugged with cerumen/debris

  • The hearing aid has accumulated internal moisture


Living in locations with humid climates such as Dubai and Miami may cause the blockage of the microphone or the speaker of the hearing aid with moisture. Please see the other article on HearingNow about how to clean a hearing aid when exposed to moisture or water.


But in my experience, the ear wax is the usual suspect. people who their body create a lot of ear wax are prone to have the speaker of the hearing aid (some call it receiver) blocked by ear wax.





Group C (repair)

After all your hearing aid may be faulty. They work 10-15 hours a day, 7 days a week. They are the estate of the art technology which is usually exposed to moisture, shock, vibration and heat (IIC, CIC, ITE, ITC). Here are examples of symptoms in which your hearing aids might be faulty.

  • There is no sound coming out of the speaker (please refer to the brochure of your hearing aid to rule out the chance of blockage of the speaker and/or the microphone inlet by dust, ear wax or moisture)

  • One of the hearing aids sounds suddenly or gradually drops to about half

  • A steading clicking or buzzing sound is heard on one of the hearing aids

  • The run time of your rechargeable hearing aid has been dropping

  • The wire that connects the hearing aid to the speaker (some call it the receiver) is loose, kinked or broken


If you experienced any of the above scenarios the best is to contact your hearing care professional for help, especially if your hearing aids are under warranty. If not, please feel free to contact us for a free consultation on your faulty hearing aid.
