If the ITV120 water timer is not working as expected during setup or everyday operation, the troubleshooting information below can help identify possible causes and recommended solutions.
Situation 1: Water leaks from the inlet connection
Possible causes
- The inlet filter is missing or not positioned correctly
- The faucet connection is loose or the threads are not aligned properly
- The faucet size is not compatible with the timer
What to do
- Check that the inlet filter is installed correctly and sits flat
- Remove the timer, realign the threads, and reinstall it carefully
- Tighten the connection by hand only
- Do not use tools or overtighten the connection
Situation 2: Water does not flow or will not stop
Possible causes
- The internal valve may be inactive after storage or transportation
- Dirt or debris may be blocking the valve or inlet filter
- The valve may need to be reactivated after a long period of inactivity
What to do
- Turn off the faucet before testing
- Activate the valve using Manual Watering
- Open and close the valve several times to restore normal movement
- Check and clean the inlet filter if necessary
- Test again with the faucet slightly open
Situation 3: Automatic watering does not start
Possible causes
- The current time or watering schedule is not set correctly
- The required watering day is not selected
- The timer is set to OFF
- Rain Delay is currently active
What to do
- Check the current time and programmed watering schedule
- Confirm that the correct watering days are selected
- Make sure the timer is not in OFF mode
- Check whether Rain Delay is active and cancel it if necessary
ITV120 allows individual watering days from Monday through Sunday to be selected, so the selected days should be checked when a schedule does not run as expected.
Situation 4: Rain Delay does not work as expected
Possible causes
- The Rain Delay setting was not completed correctly
- The selected delay period has not been activated
- Rain Delay is already active
What to do
- Check the Rain Delay setting
- Select the required delay period: 24, 48, or 72 hours
- Confirm the setting as instructed on the timer
- Cancel the current Rain Delay before setting a new one if necessary
Situation 5: The LCD screen is blank or unresponsive
Possible causes
- The batteries are depleted or installed incorrectly
- Old and new batteries or different battery types are being used together
- The battery compartment is not installed securely
What to do
Replace the batteries with 2 new AA alkaline batteries
Check the battery polarity
Do not mix old and new batteries or different battery types
Reinstall the battery compartment and make sure it is fully secured
Situation 6: Water flow or pressure is lower than expected
Possible causes
- The inlet filter is clogged with dirt or debris
- The available inlet water pressure is too low
- The hose or watering setup is restricting water flow
What to do
- Remove and clean the inlet filter
- Check the faucet and hose connections
- Test the timer with a simpler watering setup
- Confirm that the water pressure meets the timer's specified operating range
