The Aquastop with fork sensor: water detected, appliance switched off, damage prevented
The Schabus Aquastop SHT 216 is a plug-and-play water detector with automatic appliance shut-off. It is inserted between the wall socket and the appliance, for example in front of a washing machine or dishwasher. As soon as a conductive liquid bridges both metal contacts of the fork sensor, it warns acoustically and optically and immediately disconnects the connected appliance from the mains.
The fork sensor reacts even to the smallest amounts of water. A small crack in the hose is enough, and the power is cut before the water can spread. Via the switchable socket, a normally closed solenoid shut-off valve can also be controlled, which interrupts the water supply in the event of an alarm.
The SHT 216 requires neither batteries nor programming: plug in, mount the sensor, connect the appliance, perform a function test. It is intended for use in residential areas as well as in commercial and business premises and small businesses.
Important note: The SHT 216 is operated with 230 V mains voltage and has no battery. In the event of a power failure, it cannot issue an alarm. It is not intended for permanent underwater applications, must not be operated outdoors and must be protected from moisture, splash water and direct sunlight. It is not suitable for non-conductive liquids such as heating oil or diesel.

How the SHT 216 is constructed
A compact socket device, a permanently connected fork sensor and a protective cap: that is all the Aquastop needs.
Housing with Schuko plug and socket
The device is plugged into a properly installed 230 V socket. The mains plug of the appliance to be monitored is plugged into the integrated socket.
Plug lock
The protective cap over the socket protects the connected plug against accidental unplugging.
Status indicator
The indicator lights up green when the Aquastop is ready for operation, and red in the event of an alarm.
Acoustic signal generator
The signal generator warns loudly and audibly in the event of an alarm.
Sensor cable
The permanently mounted LIYY cable (2 x 0.14 mm²) is 2.8 m long. It is briefly waterproof, flame-retardant, self-extinguishing and largely resistant to oils, greases, coolants and lubricants. It is not intended for permanent underwater installation.
Fork sensor with two brass contacts
Two nickel-plated brass contacts detect water. As soon as a conductive liquid bridges both contacts, the Aquastop is triggered.
Mounting hole
The fork sensor is fastened with a screw and wall plug via the mounting hole in the sensor.
How the SHT 216 works
Normal state
The sensor contacts are dry. The status indicator lights up green and the connected appliance, e.g. a washing machine, is in operation.
Water contact
Both metal contacts of the fork sensor are bridged by water. The Aquastop detects the water.
Alarm and shut-off
The alarm sounds, the status indicator lights up red and the connected appliance is switched off.
The Aquastop remains in the alarm state until the sensor is no longer in contact with water and the device is briefly disconnected from the mains. There is no automatic restart: after the cause has been eliminated, the device must be reset manually.
Mount the sensor, put the Aquastop into operation
Installation is plug-and-play. A specialist company is not strictly required, but is recommended, for example, for a solenoid shut-off valve.
Mounting the fork sensor
Select mounting location
Mount the sensor where escaping water is detected as early as possible, e.g. next to a washing machine, dishwasher or heating system.
Position the sensor
The two metal contacts must point downwards and touch the floor to be monitored or be positioned immediately above it.
Secure the sensor
Secure the sensor via the mounting hole. Both metal contacts must remain free and must not be covered by objects.
Commissioning
- Mount the fork sensor as described.
- Plug the Aquastop into a properly installed 230 V socket.
- Plug the mains plug of the appliance to be monitored into the socket of the Aquastop and secure the protective cap against accidental unplugging.

Causes and solutions
Indicator does not light up
Possible cause: No mains voltage or Aquastop not fully plugged in.
Remedy: Check that the Aquastop is fully plugged in. Check the power supply of the socket with another appliance.
No alarm on water contact or function test
Possible cause: Water does not touch both metal contacts at the same time or the contacts are dirty.
Remedy: Touch both contacts simultaneously with a damp cloth. Clean dirty contacts and repeat the function test.
Alarm cannot be reset
Possible cause: Sensor contacts are still damp or continue to be bridged by conductive liquid.
Remedy: Remove the liquid, dry both contacts completely, then briefly disconnect the Aquastop from the mains and plug it in again.
Frequent or unexplained alarms
Possible cause: Moisture, condensation, contamination or an unfavourable sensor position.
Remedy: Check and clean the sensor. Check the mounting location: the contacts may only come into contact with liquid in the event of an actual water leak.

Frequently asked questions
How do I install the SHT 216?
Installation is plug-and-play: mount the fork sensor at the desired location, plug the Aquastop into the socket, connect the appliance, perform a function test. A specialist company is not strictly required, but can be involved, e.g. for the solenoid shut-off valve.
Which appliances can I connect?
The SHT 216 is suitable for household appliances that use water, e.g. washing machines, dishwashers or boilers. The maximum switching capacity is 230 V at 3500 VA.
Does the SHT 216 also detect the smallest amounts of water?
Yes. The fork sensor reacts as soon as an electrically conductive liquid bridges both metal contacts. Correct positioning of the sensor is decisive.
Where should I mount the water sensor?
As close as possible to the point where escaping water is likely to appear first, e.g. next to or behind a washing machine or dishwasher. The two metal contacts must point downwards and touch the floor or be positioned immediately above it.
How am I warned when water is detected?
On water contact, an acoustic and an optical warning occur simultaneously: the signal generator sounds, the status indicator lights up red. In addition, the device automatically switches off the connected appliance.
What happens after a water alarm? Do I have to reset the Aquastop?
Yes. After the cause has been eliminated and both sensor contacts are dry again, the Aquastop must be briefly unplugged from the socket and plugged in again. There is no automatic restart.
Does the Aquastop also shut off the water supply to my washing machine?
Not directly. In the event of an alarm, the SHT 216 first interrupts the power supply to the connected appliance. If the water supply is also to be closed, a suitable normally closed solenoid shut-off valve can be controlled via the switchable socket. Installation should be carried out by a specialist company.
Can I extend the water sensor?
Yes. The sensor cable is 2.8 m long and can be extended with a LIYY cable (max. 2 x 0.14 mm²) up to 50 m. To do this, the existing cable is cut and reconnected with terminals. For longer cables, a specialist is recommended. On request, the manufacturer can supply the device from the factory with your desired length – please contact us. The matching cable has Art. No. 300780.
Is the sensor waterproof?
The LIYY cable is briefly waterproof, flame-retardant, self-extinguishing and largely resistant to oils, greases, coolants and lubricants. Permanent underwater applications are not permitted, however.
Does the device also work with heating oil, diesel or oil products?
No. The fork sensor only detects conductive liquids. For non-conductive liquids such as heating oil, diesel or vegetable oil, the SHT 226 with mini float switch (Art. No. 300228) is required.
How do I check whether my Aquastop is working correctly?
Touch both metal contacts of the sensor simultaneously with a damp cloth. The Aquastop must then alarm acoustically and optically and switch off the appliance. Then dry the contacts and reset the device by briefly disconnecting it from the mains. At least one function test per month is recommended.
What happens in the event of a power failure?
The SHT 216 requires 230 V mains supply and has no battery. During a power failure it therefore cannot issue an alarm. After the mains voltage is restored, operational readiness should be checked.
Can I use the Aquastop in the basement or in an unheated laundry room?
Yes, provided the permissible ambient conditions are observed. The SHT 216 is designed for temperatures from −15 °C to +40 °C and has protection class IP 20. The intermediate plug device must remain protected from moisture, splash water and direct wetness.
What to do in the event of frequent or unexplained alarms?
Possible causes are moisture, condensation, contamination or an unfavourable sensor position. Check and clean the sensor and check the mounting location: the contacts may only come into contact with liquid in the event of an actual water leak.
How long does the guarantee last?
The statutory warranty of at least 2 years applies in the EU. In addition, the manufacturer Schabus offers a 5-year guarantee that can be registered online.
