Replace S27-352 cartridge.
Test the station to determine the cause.
1. Disconnect the wires from the cartridge of an adjacent valve. Disconnect the wires from the
problem valve and reconnect to the adjacent valve.
2. Turn on electrical and water supplies to the unit. Pass your hand in front of the sensor of the
problem station, and the adjacent station should turn on.
If the adjacent station turns on and cycles normally, replace the cartridge on the problem valve.
If the adjacent valve fails to turn on, inspect the wires from the sensor cable and do the following:
• make sure there are no breaks and that the fully insulated disconnect terminals are firmly
crimped in place;
• turn off the electrical and water supplies;
• reconnect to the adjacent valve and turn on the water supplies to the unit;
• pass your hand in front of the sensor. If the station still fails to turn on, replace the sensor.
