🧰 How to Repair a CLACK Water Softener When It Stops Working 💦

If your CLACK water softener has stopped working, don’t stress 😰 — you're in the right place. These systems are built to last, but like all home appliances, they can develop faults over time. In this easy-to-follow guide, we’ll show you how to diagnose and fix common CLACK water softener problems — even if you're not a plumber!

🔧 Most Common CLACK Water Softener Issues (And How to Fix Them) 👇

⚙️ 1. System Isn’t Regenerating Automatically

Symptoms: Hard water 🚿, soap won’t lather 🧼, white limescale buildup ❌

💡 Causes:

• Incorrect regeneration settings

• Timer error or power failure

• Glitch in the control head

✅ Fix It:

• Double-check the regeneration schedule on the screen 🕒

• Unplug for 10 seconds and plug it back in to reset 🔁

• No power? Check fuse or outlet 🔌

🧂 2. Salt Level Not Dropping

Symptoms: Salt stays full ⛔ but water doesn’t feel soft 🤔

💡 Causes:

• Salt bridge (hardened layer) 🧱

• Clogged brine line or injector 🚫

• Jammed float valve

✅ Fix It:

• Use a broom handle to gently break salt crusts 🧹

• Clean the brine line and injector with warm water or vinegar 🧴

• Make sure the float valve moves freely 🆙🆗

🚰 3. Constant Drain Flow

Symptoms: Water constantly running to drain 💸 or strange noises 😣

💡 Causes:

• Stuck piston in the valve head 🛑

• Worn seals or debris inside

✅ Fix It:

• Run a manual regeneration to test the piston 🔄

• Remove the valve cover and inspect the piston and seals 🔍

• Replace worn parts (available from suppliers or EcoFilter!) 🔧

🧾 4. CLACK Error Codes

Common Codes:

• Err 1 = Motor failure ⚠️

• Err 2 = Piston jammed ⛓️

• Err 3 = Switch issue 🔄

✅ Fix It:

• Reset the unit 🔁

• Open the valve head and test motor/switch ⚡

• Replace faulty parts if needed (we stock them!) 📦

💧 5. Low Water Pressure After Installation

Symptoms: Weak water flow 🚿, taps struggling to run

💡 Causes:

• Bypass valve not fully open 🧩

• Resin clogged or fouled up 🧪

✅ Fix It:

• Fully open bypass valves 🔓

• Clean or replace the resin bed if it's an older system ⏳
