Keeping your Aquasure Harmony Series water conditioner running at peak efficiency is simpler than you might think. Regular maintenance prevents scale buildup, protects the digital components, and ensures you enjoy soft, conditioned water for years. This guide walks you through the specific cleaning steps and routine checks your Harmony conditioner needs, based on real owner experiences and the manufacturer’s best practices.
How Often Should I Clean the Pre-Filter on My Aquasure Harmony Series?
The Aquasure Harmony Series uses a sediment pre-filter to catch larger particles before they reach the conditioning media. This is your first line of defense. For most households, the pre-filter cartridge should be inspected every 30 days and replaced every 3 to 6 months. If your water comes from a well or has visible sediment, check it every two weeks.
Cleaning the reusable pre-filter (if your model includes one) is straightforward:
- Turn off the water supply and release system pressure using the bypass valve.
- Unscrew the clear filter housing using the included wrench.
- Remove the filter cartridge and rinse it with warm, clean water. Avoid soap or detergents.
- If the cartridge is discolored or feels slimy, replace it immediately.
- Inspect the O-ring on the housing for cracks or debris, then reassemble.
Neglecting the pre-filter is the most common cause of reduced flow and premature wear on the conditioner’s internal components. It is cheap insurance for your system.
What Is the Correct Way to Clean the Conditioning Media Tank?
The Harmony Series uses a catalytic media (often called template-assisted crystallization or TAC) that does not require salt regeneration, but it does need occasional cleaning of the media tank. The media itself is very durable, but mineral fines and organic matter can accumulate over time.
Perform a media tank flush every 12 to 18 months, or if you notice a drop in water pressure or a musty smell from the conditioned water. Here is the process:
- Place the system in bypass mode.
- Disconnect the outlet line from the control valve.
- Attach a garden hose to the outlet port of the valve and run it to a floor drain or outside.
- Open the bypass slightly to allow a slow flow of water through the tank in reverse. Let it run for 5 to 10 minutes until the water runs clear.
- Reconnect the outlet line and return the system to service.
This backflush action dislodges any trapped particles. If your model has a manual flush port, use that instead. For a deeper clean, some owners use a mild citric acid solution (1 cup food-grade citric acid per 5 gallons of water) circulated through the tank, but always consult your owner’s manual first.
Maintaining the media is a core part of the Aquasure Harmony Series Salt-Free Benefits: Why Choose a Conditioner—it stays effective for years without bags of salt.
How Do I Clean the Digital Display and Control Panel?
The smart digital display on the Aquasure Harmony Series is sensitive to moisture and abrasive cleaners. Use only a soft, lint-free microfiber cloth slightly dampened with distilled water. Wipe the screen gently to remove dust, water spots, or finger smudges.
Do not apply any spray directly to the display. Spray the cloth first. Avoid alcohol-based, ammonia-based, or petroleum-based cleaners—they can damage the coating and cause discoloration. Check the gasket around the display annually; if it is cracked or lifting, replace it to prevent water intrusion into the electronics. For more details on interpreting the readings, see our article on Aquasure Harmony Series Smart Features: Understanding the Digital Display.
| Maintenance Item | Usual Frequency | Needs Attention Soon |
|---|---|---|
| Pre-filter inspection | Every 30 days | If you see discoloration, slime, or a 10+ psi pressure drop across the housing. |
| Media tank backflush | Every 12–18 months | If pressure drops noticeably at multiple faucets or water develops a stale odor. |
| Digital display cleaning | As needed, ~every 2 months | If buttons become unresponsive or moisture appears behind the screen. |
| O-ring and seal inspection | Every 6 months | If you see water pooling near fittings or notice a faint leak smell in the utility area. |
What Routine Checks Does the Control Valve Need?
The control valve is the brain of your conditioner. It meters water flow and triggers any automatic flushes. Most Aquasure Harmony models have a sealed valve that requires no lubrication, but you should inspect the electrical connections yearly.
Turn off power to the system and remove the valve cover. Look for:
- Corrosion or rust on the circuit board or wiring terminals.
- Loose wire connectors.
- Signs of insect nests or dust buildup (use a small soft brush to clean).
If your installation site is damp, consider adding a small desiccant pack inside the valve compartment. Also, listen for unusual ticking or grinding sounds during a flush cycle—this could indicate a gear or motor issue that needs professional service.

How Do I Sanitize the System After a Long Vacation or Outage?
If your Aquasure Harmony Series has been unused for more than two weeks (such as after a vacation or a power outage), sanitizing prevents bacterial growth inside the media tank and tubing. Use only NSF-approved sanitizer like hydrogen peroxide solution (3%, food grade) or a small amount of unscented chlorine bleach—but check your manual first. The general steps are:
- Pour 1 cup of your chosen sanitizer into the brine well (if equipped) or directly into the distributor tube opening if no brine system is present.
- Bypass the conditioner and let the sanitizer sit for 15 minutes.
- Flush the system with water for 5 minutes before restoring full service.
Always run the nearest faucet until the water no longer smells of sanitizer before using it for drinking. After a long outage, also run a manual regeneration cycle if your model supports it.
What Owners Say
“I forgot to check the pre-filter for five months and our flow went down to a trickle. A quick rinse fixed it, but now I set a phone reminder every 30 days. So simple.” — Michael T., Phoenix, AZ
“The digital display on our Harmony got a bit cloudy after we used a glass cleaner with ammonia. Now I only use a damp microfiber cloth. The manual warned us, but we didn’t listen.” — Linda K., Orlando, FL
“After a five-week trip, the water had a slight metallic smell. We followed the sanitizing steps with hydrogen peroxide, ran the flush, and it was gone. No issues since.” — Raj P., Austin, TX
Frequently Asked Questions
Q: Can I use vinegar to clean the media tank on my Aquasure Harmony?
No. White vinegar is not recommended for the Harmony Series. The acid can damage the catalytic media over time. Stick to a backflush with clean water or a manufacturer-approved citric acid solution in very specific doses.
Q: How do I tell if the pre-filter on my Aquasure Harmony needs replacing?
A pressure drop of 10 psi or more between the inlet and outlet gauges (if installed) is the clearest sign. Visually, if the filter is dark brown, green with algae, or slimy, replace it immediately. Otherwise, every 3 to 6 months is standard.
Q: My Aquasure Harmony display is dim—is that a maintenance issue?
A dim display often indicates a dirty screen or low power. Clean the screen gently with a dry microfiber cloth first. If still dim, check the power supply connection and the fuse. If the display is cracked, contact Aquasure support for a replacement module.
Q: Is it safe to use a pressure washer to clean the outside of the Harmony conditioner?
No. High-pressure spray can force water into the control valve and electronics, potentially causing short circuits. Use a garden hose on low pressure or a sponge and bucket for the outside tank.
Q: Do I need to unplug the Harmony when cleaning it?
Yes, always unplug the system from the wall outlet before performing any cleaning that involves water, removing covers, or handling internal components. This is critical for safety and to prevent damage to the electronics.
Q: How often should I replace the O-rings on my Aquasure Harmony?
Replace O-rings every 2 to 3 years, or at the first sign of leakage. Apply a thin layer of silicone-based plumbing grease to new O-rings to extend their life and ensure a proper seal.
