Water inlet solenoid does not turn OFF
•
Check the water inlet solenoid closes within 5 seconds of turning the 240 Volt
power OFF.
•
Check the Trident wiring loom is connected to the N-E5 and the plug connection is
good.
•
Check the Trident loom circuit output and water contact sensitivity at both the
probe and the N-E5 plug terminals (see test procedure Trident Water Management
section)
If loom not connected (open circuit)
•
N-E5 Error 50 - Water inlet solenoid open for 15 minutes before lockout.
Check that the water inlet solenoid is not energised (240 Volt) at the WATER INLET
SOLENOID-ACTIVE & NEUTRAL terminals.
If power present:
•
Check if the Networker is turned ON and cooling required.
•
Check the Cooler water level is not at a level that requires the water inlet
solenoid to be energised.
•
Check the Cooler is not in a pre-program operation, requiring the water inlet
solenoid to be operating i.e. wash or flush function.
If no power:
•
Check the water inlet solenoid has not blocked or jammed open.
