Installation Verge™Faucets
Troubleshooting – Solenoid Valve
Problem Cause Solution
Faucet fails to shut off and drips. The cartridge valve is defective. Replace cartridge with part number S27-352A.
Faucet fails to turn on. A failed valve or loose electrical
connection to the connectors.
1. Repair loose connection.
2. If possible, determine whether sensor, power adapter
or valve is defective by swapping parts with an adjacent
faucet. Replace defective part.
Faucet doesn't activate. Blocked sensor. 1. Clean sensor lens with soft, damp cloth.
2. Unplug power supply or remove batteries.
3. Reconnect power supply or install new batteries.
Before attempting to troubleshoot the valve or disassemble the components, check for the following conditions:
• If stop valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no cross-
connections or leaking stop valves.
• Check the hot water heater output to make sure that it is at least 10°F above the set temperature.

LED Indicators
Close the appropriate shut-off valves prior to disassembly and reopen valves after inspection and
repair is complete.
Problem Cause Solution
External leaks. Damaged cartridge or
O-rings.
Replace cartridge with part number 269-1927.
Improper water temperature
or temperature fluctuation.
Hot water supply is not
10° above desired set
point.
Increase hot water supply temperature.
Valve temperature is not
properly set.
Adjust the temperature as shown on page 4 step 3.
Limited water flow. Dirt and debris have built
up in the valve or strainer.
1. Check to make sure both hot and cold supplies are connected to
the Navigator mixing valve and that they have water flow.
2. Remove cover and U-clip. Remove the cartridge and clean the
strainer. It is not required to grease cartridge, however if desired,
use silicone grease only.
Do not use grease on check valves.
