Check the Cooler's operation is not in a delay period preventing the pump from

(MAINS/ACTIVE-IN and NEUTRAL terminals).
Check the N-E5 module is turned ON and is correctly located in the mounting plug.
Empty the tank of all water and then drive the pump with your multimeter on
Amps. Caution: only a qualified electrician should perform this procedure,
because this involves full current 240 volt electricity.

Check the pump loom and all terminals.
Check the N-E5 internal 8 Amp fuse is not open circuit.
