Steps

Goal: Confirm the symptom, then check the battery, sensor, and solenoid.

  • Touch the faucet spout or handle to activate it. The faucet should turn on or off.
  • Good: The faucet does not respond—proceed to Replace battery.
  • Bad: The faucet responds—no repair needed.

Replace battery

Goal: Rule out a dead or low battery.

  • Locate the battery compartment—usually under the sink near the solenoid, or in the base of the faucet. Check your owner’s manual or search “[brand] [model] touch faucet battery” for the location.
  • Remove the old battery and install a fresh one (usually AA or 9V). Confirm the polarity is correct.
  • Good: The faucet responds to touch after the battery is replaced.
  • Bad: Still no response—proceed to Check sensor.

Check sensor

Goal: Rule out a dirty or damaged sensor.

  • Wipe the sensor with a soft cloth. Remove any water spots, soap film, or debris. The sensor must be clean and dry for touch detection to work.
  • Check for cracks or damage. If the sensor is damaged, you may need a new faucet or a plumber.
  • Good: The sensor is clean and the faucet responds.
  • Bad: Still no response—proceed to Check solenoid.

Check solenoid

Goal: Rule out a faulty solenoid.

  • The solenoid is the valve that opens and closes when the sensor triggers. It is usually under the sink in the supply line.
  • Touch the faucet and listen for a click. If you hear nothing, the solenoid may have failed. Check the wiring from the sensor to the solenoid.
  • If the solenoid does not click, replace it. Shut off the supply valves, disconnect the old solenoid, and install a replacement that matches your model.
  • Good: The solenoid clicks and the faucet responds. If it clicks but no water flows, check the supply valves.
  • Bad: The solenoid does not click and you cannot replace it—call a plumber.

When to get help

Call a plumber if:

  • You have replaced the battery and cleaned the sensor and it still will not respond.
  • The solenoid needs replacement and you cannot access it or match the part.
  • The faucet body or wiring is damaged.

Verification

  • The faucet turns on or off when you touch the spout or handle.
  • The solenoid clicks when you touch the faucet (listen under the sink).
  • The manual override (handle) still works if the touch feature is off.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the faucet does not respond to touch.
  2. Replace battery Install a fresh battery in the correct compartment.
  3. Clean sensor Wipe the sensor dry and remove debris or water spots.
  4. Check solenoid Listen for a click; replace if it does not activate.
  5. Call a plumber Solenoid faulty and cannot be replaced, or faucet still will not respond.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Faucet brand and model
  • Battery type and when last replaced
  • Whether the solenoid clicks when touched
  • Steps already tried

Does the touch faucet fail to respond?

Touch the spout or handle. The faucet should turn on or off. If nothing happens, check battery, sensor, and solenoid.

Touch the faucet spout or handle per your model. Good: no response—proceed to check battery. Bad: faucet responds—no problem.

Yes No

You can change your answer later.

No action needed

The touch faucet responds correctly. No repair needed.

Done

Is the battery fresh?

Touch faucets use a battery—usually AA or 9V. A dead battery is the most common cause.

Locate the battery compartment (under the sink or in the faucet base). Replace with a fresh battery. Fresh: if it works, done. Still no response: proceed to check the sensor.

Yes (works now) No (still no response)

You can change your answer later.

Is the sensor clean and dry?

Debris, water spots, or soap film can block touch detection.

Wipe the touch faucet sensor with a soft cloth. Remove water spots and debris. Clean and dry: if it works, done. Still no response: proceed to check the solenoid.

Yes (works now) No (still no response)

You can change your answer later.

Does the solenoid click when you touch the faucet?

The solenoid opens and closes the water. Listen for a click under the sink.

Touch the faucet and listen under the sink for a click from the solenoid. No click: solenoid may have failed—replace it or call a plumber. Clicks but no water: different issue (valve stuck, supply off).

Yes (clicks) No (no click)

You can change your answer later.

Replace solenoid and test

Shut off the supply valves. Disconnect the solenoid from the supply lines and wiring. Install a replacement that matches your model. Reconnect and turn water on slowly. The faucet should respond to touch.

Done

Call a plumber

Call a plumber if: the solenoid clicks but no water flows (valve or supply issue); you have replaced the battery and cleaned the sensor and it still will not respond; or you cannot access or replace the solenoid.

Done

Where is the battery in a touch faucet?
The battery is usually in a compartment under the sink, near the solenoid, or in the base of the faucet. Check your owner's manual or search "[brand] [model] touch faucet battery" for the location.
When should I call a plumber for a touch faucet that will not respond?
Call a plumber if you have replaced the battery and cleaned the sensor and it still will not respond, the solenoid needs replacement and you cannot access it, or the faucet body is damaged.
