Hearing Aid Troubleshooting Guide

Hearing Aid: No Sound, Low Volume, or Distorted Sound

Check the Battery

Ensure the battery is new, correctly inserted, and the battery door is fully closed.

Clean Your Hearing Aid and Check for Damage

• Check the tubing and microphone ports for wax or debris.
• Clean according to your hearing aid fitting booklet.
• If moisture is visible in the tubing, remove it, shake to dry, and allow it to air-dry completely before reattaching. For thin tube fittings, check for kinks or pinches and replace if necessary.

Check Earmold/Dome Placement:

• Thin Tubes: Press your finger over the tube to ensure the dome is fully inserted into the ear canal.
• Earmoulds: The earmould should be fully inserted into the ear canal, with the top part of the mould fitting under the crease at the top of your ear

Check for Earwax:

Have your ears checked for wax at your GP surgery or during a repair appointment. You may need to arrange wax removal.

Check the Hook:

If there's moisture or debris in the hook, contact us for a replacement or use our drop-box service.

Check the Program:

If using a loop system, ensure you're not accidentally switched on to the loop setting when a loop is not present. Open and close the battery door to return to your default program.

Hearing Aid Making Excessive Whistling or Buzzing Sounds

Check Earmold/Dome Placement:

Thin Tubes: Press your finger over the tube to ensure the dome is fully inserted into the ear canal.

Earmoulds: The earmould should be fully inserted into the ear canal, with the top part of the mould fitting under the crease at the top of your ear

Check for Earwax:

Have your ears checked for wax at your GP surgery or during a repair appointment. You may need to arrange wax removal.

Check Earmold/Dome Condition:

Inspect the dome or earmold for signs of wear or damage.

If you have damaged/worn thin tubes, replace them.

If you have damaged/worn earmolds, contact us to arrange for a new earmold.

If the problem persists: If these steps don't resolve the whistling or buzzing, please contact us to schedule a repair appointment. In the meantime, if your hearing aids have a volume control, you can temporarily reduce the volume to minimize the feedback.

Hearing Aid Playing 8 Consecutive Beeps

An 8-beep signal indicates a potential fault. Please contact us to schedule a repair appointment, or use our postal repair or drop-box service.

The Earmould/Dome is Causing Discomfort

If your earmold or dome is uncomfortable, first check its placement.

• Thin Tubes: Press your finger over the tube to ensure the dome is fully inserted into the ear canal.
• Earmoulds: The earmould should be fully inserted into the ear canal, with the top part of the mould fitting under the crease at the top of your ear

Incorrect placement can cause significant discomfort. If the discomfort continues after correct insertion, please schedule an in-person appointment with an audiologist to ensure the earpiece is suitable.
