Touchless toilets have revolutionized the bathroom experience, offering hands-free convenience and enhanced hygiene. Among the leading brands, American Standard stands out as a reputable manufacturer known for its innovative touchless toilet technology. However, even with advanced engineering, these touchless toilets may encounter operational issues that can disrupt their otherwise seamless performance. In this comprehensive article, we will delve into seven common problems users may encounter with American Standard touchless toilets, explore their root causes, and provide practical solutions to rectify them effectively.
Problem #1: Non-Responsive Touchless Sensor
A non-responsive touchless sensor is one of the most frequent issues faced by users. When users wave their hand over the sensor, the toilet fails to detect movement or activate the flush, rendering the touchless feature ineffective.
Causes:
- Obstruction in front of the sensor: Over time, dirt, dust, or tiny debris can accumulate on the sensor’s surface, impairing its ability to detect motion accurately.
- Sensor calibration issues: Improper calibration can lead to erratic sensor performance, where it may not respond consistently to hand gestures.
- Low or depleted battery power: If the sensor’s batteries are low on power or completely drained, the touchless system will not function correctly.
Solutions:
- Check for any obstructions in front of the sensor and clean it regularly with a soft, lint-free cloth and mild soap. Avoid using harsh chemicals or abrasive materials that could damage the sensor’s surface.
- Recalibrate the sensor according to the manufacturer’s guidelines. This usually involves adjusting sensitivity settings and ensuring the correct range for optimal performance.
- Replace or recharge the batteries as necessary. It is essential to use high-quality, long-lasting batteries to maintain consistent touchless sensor functionality.

Problem #2: Constant Flush or Water Running
When a touchless toilet experiences a constant flush or a continuous water flow, it can lead to water wastage, increased water bills, and potential flooding.
Causes:
- Faulty or worn-out flapper or flush valve: The flapper and flush valve are critical components responsible for regulating water flow. If these components are damaged or worn, they may not close properly, causing continuous water flow.
- Malfunctioning fill valve: The fill valve controls the flow of water into the toilet tank. A faulty fill valve can result in an incomplete fill cycle, leading to constant flushing or water running.
Solutions:
- Inspect the flapper and flush valve for signs of damage or wear. If there are any visible issues, promptly replace them with genuine American Standard parts.
- Check the fill valve for defects, such as leaks or clogs, and replace it with a compatible and reliable fill valve.
- Ensure stable water pressure in the toilet’s supply line and adjust it to the recommended levels. Excessive water pressure can lead to continuous flushing or water running even after the tank is full.
Problem #3: Inconsistent Flush
An inconsistent flush occurs when the touchless toilet either flushes partially, leaving behind waste, or fails to flush at all, causing inconvenience and unsanitary conditions.
Causes:
- Insufficient water level in the tank: If the water level in the toilet tank is too low, it may not provide enough force to complete a proper flush.
- Clogged rim jets or trapway: Accumulated mineral deposits, limescale, or debris can obstruct the rim jets or trapway, reducing the efficiency of the flush.
- Issues with the flapper or flush valve: A misaligned or damaged flapper or flush valve can lead to incomplete flushing.
Solutions:
- Adjust the water level in the tank to the manufacturer’s recommended setting. Typically, the water level indicator or fill line indicates the appropriate level.
- Thoroughly clean the rim jets and trapway to eliminate blockages. Use a suitable toilet bowl cleaner and a toilet brush to remove any stubborn deposits.
- Examine the flapper and flush valve for any damage or misalignment, replacing them if necessary. Ensure that the flapper sits properly and forms a watertight seal when closed.

Problem #4: Phantom Flushing
Phantom flushing occurs when the touchless toilet flushes unexpectedly without any user interaction. This phenomenon can lead to unnecessary water wastage and increased water bills.
Causes:
- Water leaking from the tank into the bowl: A faulty flapper or flush valve may not seal correctly, allowing water to leak continuously into the bowl, which triggers the touchless sensor inadvertently.
- The touchless sensor detecting false movements: Certain external factors, such as nearby objects or sudden temperature changes, may cause the touchless sensor to register false readings.
Solutions:
- Inspect the flapper and flush valve for any signs of wear or damage. Replace them if they are not creating a proper seal and are allowing water to leak into the bowl.
- Adjust the sensor’s sensitivity settings to ensure that it responds only to intentional hand gestures and not to external disturbances.
- Relocate objects or eliminate environmental factors that could trigger false sensor readings.
Problem #5: Weak or No Water Flow
A touchless toilet experiencing weak or no water flow can make it challenging to clear the bowl effectively, leading to potential sanitation issues.
Causes:
- Low water pressure in the supply line: Insufficient water pressure can hinder the toilet’s flushing efficiency.
- Blockage in the toilet’s inlet holes: Accumulated debris or mineral deposits can clog the toilet’s inlet holes, restricting water flow.
- Malfunctioning fill valve: A damaged or malfunctioning fill valve may not allow adequate water to enter the tank, resulting in a weak flush.
Solutions:
- Check the water pressure in the supply line and ensure it meets the minimum requirement specified by the manufacturer. If the pressure is low, consider contacting a plumber to address the issue.
- Clear any blockages in the inlet holes with a gentle wire or plumbing snake. Avoid using sharp objects that could scratch or damage the porcelain surface.
- Inspect the fill valve for defects and replace it if needed. A fully functional fill valve ensures a sufficient amount of water is available for a robust flush.

Problem #6: Unexpected Sensor Range
The touchless sensor may exhibit an unusually short or long range, causing inconsistent flush activation and user frustration.
Causes:
- Incorrect sensor calibration: Improper calibration during installation or routine maintenance can lead to erratic sensor performance and misreading hand gestures.
- Accumulation of dirt or grime on the sensor: Over time, the touchless sensor’s surface may collect dirt and grime, impairing its sensitivity and detection capabilities.
Solutions:
- Recalibrate the touchless sensor according to the manufacturer’s guidelines. Calibration adjustments should align with the intended range and sensitivity of the sensor.
- Clean the touchless sensor regularly with a soft, damp cloth to remove dirt and maintain its sensitivity. Avoid using abrasive materials or harsh chemicals that could damage the sensor’s surface.
Problem #7: Water Leakage around the Base
Water pooling around the base of the touchless toilet can be a distressing issue, potentially leading to damage to the bathroom floor and subflooring.
Causes:
- Loose or damaged wax ring: The wax ring serves as a seal between the toilet base and the waste pipe. If it becomes loose or damaged, water can escape and seep onto the floor.
- Cracked toilet base: A crack in the toilet’s base can allow water to leak out during flushing, causing water puddles around the toilet.
Solutions:
- Shut off the water supply to the toilet and carefully inspect the wax ring. If the wax ring appears compromised, it is crucial to replace it promptly to restore the seal between the toilet and the waste pipe.
- If the toilet base is cracked, it is essential to replace the entire toilet unit to prevent further leakage. A cracked base cannot be repaired effectively and can lead to ongoing water issues.
