Does the Dalmo touchless faucet have batteries?
Yes, the Dalmo touchless faucet uses four AA batteries with 1.5-2 years of battery life. When the sensor light starts flashing, it indicates low batteries that require changing.
Dalmo faucet sensor is not working.
If water is not flowing from the faucet when using the sensor, follow the troubleshooting tips below.
- Ensure the water shut-off valves are open to confirm the faucet is receiving water.
- Verify the handle is in the open position.
- Check the control box, make sure the auto/manual settings button is on sensor mode.
- Check if the batteries are working and they are in the correct polarity. When the sensor light blinks, you should replace the batteries.
- Wipe off water, dirt, or mineral buildup from the sensor eye with a microfibre cloth. Then, wave your hand in front of the sensor within a distance of 6cm and then pull down the handle.
- Open the override and check if the water is in manual mode. If there is no water, close the water supply to the faucet. Disconnect the top water line to the electronic unit and ensure the filter is clean. If the filter is not clean, use a toothbrush and dishwashing soap to remove dirt and rinse it thoroughly. Close manual override and try the sensors again.
- If the sensor light is not blinking and no water is coming out when you wave your hand over the sensor, replace the faucet body.
How to adjust sensitivity on Dalmo faucet
The Dalmo touchless faucet has a dual sensor that detects hand or object movement in two sensing zones for effective movement detection. The default sensor range is usually between four to five inches, but you can adjust the sensor range using the following steps.
- Reset your touchless faucet. Water will start flowing and then stop.
- The red LED light will turn solid and then go off.
- Before the second flash comes on, place your hand at the desired distance. The red light will start flashing for about five seconds, then stop.
- Without removing your hand, the light will stay solid for about two seconds, then go off to indicate the sensor range has reset.
- Note that you may have to repeat this several times before it works.
Dalmo touchless faucet is leaking.
A leaking faucet is a prevalent problem; however, the best way to fix the issue is by first identifying the source of leakage. Below is a breakdown of all the areas your faucet can experience leaking and how to fix it.
1. The faucet leaking at the handle
The cartridge is either loose or broken. Disconnect the cartridge and re-tighten the cartridge nuts to ensure it remains watertight. If it is damaged, replace the cartridge.
2. The faucet leaking at the bottom of the spout
The cartridge is loose or damaged. Re-tighten the cartridge or replace it.
The O-ring is either torn or not sealing correctly. Remove the cartridge and replace the rubber seal.
3. Spray leaks when the faucet is on
The sprayer is either broken or loose. Tighten the sprayer properly or replace it.
4. The faucet is leaking between the inlet hose connector and shut-off valve.
The connector is not secure, or the rubber seal in the connection is worn. Turn off the water supply, disconnect the inlet hose from the shut-off valve, replace the rubber seal and tighten the connector using an adjustable wrench.
Dalmo faucet not responding to my presence.
If your Dalmo faucet has sensitivity issues, here are some possible causes and their solutions.
- The handle is not in the open position. The handle must be open for the sensor to work. Pull the faucet handle on the right outwards to open it, then test the sensor.
- The faucet is in manual mode. When the manual mode is active, the touchless function cannot work. This feature allows you to use your faucet even when you have no batteries. Locate the auto/manual settings button on the control box underneath the sink and turn it counterclockwise to operate the faucet automatically.
- Check the condition of the batteries. The red indicator light on the faucet usually flashes when the battery is running low. If you have not changed the batteries in a while, replace them. If you changed them recently, check the polarity.
- Dirt on the sensor can block it and prevent sensitivity. So, clean the faucet spout using a lint-free cloth and mild soap to remove dirt. Then, dry the sensor lens with a dry cloth.
- The sensor can lose sensitivity when it detects steam. Turn the spout away from the sensor to redirect the steam away from the sensor.
- The sensor range could be too short if the faucet is not responding to the motion. Manually adjust the sensor range.
Dalmo faucet keeps running even after the user walks away
If the Dalmo faucet doesn’t turn off, there could be a problem with the batteries, connections, or a faulty solenoid valve.
- You may have accidentally triggered special faucet features such as “continuous run” and “temporary off.” Reset the sensor range first. If the problem persists, continue with troubleshooting.
- Sometimes an automatic faucet will stay on if the range is too long, or environmental factors such as direct sunlight, reflections, or dirt on the sensor lens easily trigger it. Reset the faucet or eliminate all possible triggers.
- Inspect the faucet system for clogs. If the water coming out of the faucet is little, check if the aerator is clogged. The aerator mixes water and air to allow for a smooth flow from the faucet. To test for a clogged aerator, remove it and turn on the faucet. If more water comes out, soak the aerator in white vinegar to remove limescale buildup, rinse it, and reinstall it.
- Inspect the faucet’s mounting for any pinched or worn washers or seals. Disassemble the spout, replace any damaged seals or washers, clean the mounting area then reconnect the faucet securely.
- There could be debris stuck in the valve, causing the faucet to run continuously or leak. The solenoid valve moves the electric current from the power source to the starter. Turn off the water, disable the valve, taking note of how the parts connect. Clean the solenoid valve by running it under tap water and scrubbing off any dirt using a toothbrush. Reassemble the valve and then test the faucet.
- If the problem persists, the solenoid valve is faulty and requires a replacement.
Can you bypass the Dalmo touchless faucet?
Yes, one of the best features of the Dalmo touchless faucet is the ability to use the faucet manually. The batteries power the sensors to detect heat, motion, or a combination and activate the faucet without physical contact.
To bypass the touchless feature:
- You can remove the batteries, therefore cutting off power to the sensor.
- Find the control box underneath the sink, turn the auto/manual button clockwise to operate the faucet manually. Then, to return the touchless feature, turn the button counterclockwise.
Dalmo touchless faucet low pressure
If your Dalmo touchless faucet has low water flow, there are a few possible reasons that can explain the issue.
- The water shut-off valve may not be fully open. Check the valve and adjust it accordingly.
- The aerator could be clogged. The aerator mixes air and water to support smooth water delivery. Remove the aerator and clean it or replace it to restore normal water flow. Clean the nozzle too to remove any debris blocking water flow.
- The solenoid filter may also be clogged and will require a replacement.
- If all these solutions do not work, your water supply to the house could be low. Most times, the municipal reduces or shuts down water flow during maintenance and repairs. Call your water provider and confirm if there are any repair works in your area.

How to clean and maintain your Dalmo touchless kitchen faucet
Although the touchless faucet is very convenient, it still requires maintenance to ensure it works properly for longer. Unfortunately, due to Dalmo faucets’ compact design, they are prone to harboring dirt and bacteria without detection. Contaminants can clog the system and also contaminate your water, hence why regular cleaning is crucial. Here are the cleaning instructions for your Dalmo touchless kitchen faucet.
- Get a mild cleaning agent with a pH between six to nine. Such a cleaner is enough to kill germs and bacteria and also maintain your faucet’s finish.
- Spray the cleaner onto a microfibre cloth. Do not spray the cleaner directly onto the faucet as it may seep into the seams that are difficult to rinse and corrode the surfaces over time.
- Use the towel to scrub down the faucet spout, handle, and deck plate.
- To remove mineral spots and stains and disinfect the faucet, fill a nylon bag with a cup of vinegar, dip the faucet spout into the bag and wrap rubber bands around it to keep it in place. Let the spout soak in the vinegar for a few hours, and then run the tap to flush out the vinegar.
- Rinse the faucet with warm water to remove all cleaning residue and dry the faucet with a soft towel.
- Clean the aerator about once a year to reduce buildup. Use a soft-bristled toothbrush to scrub the aerator and all the nooks and crannies. If the aerator is too clogged, soak it in a mixture of equal parts water and white vinegar.
- If you want to avoid the trouble of cleaning the aerator, you can replace it once a year with a new one. Aerators are inexpensive and readily available at local hardware stores.
- Other than cleaning and disinfecting your faucet, inspect them regularly for signs of wear and tear, especially around the sprayer button and nozzle opening. Inspect the seals and springs. If the parts are excessively worn, replace them.
