After connecting a water purification line to the ice maker (replacing the normal supply line in the kitchen), the ice maker stopped producing ice. When the kitchen line was re-connected, the ice maker started overflowing. The entire unit was temporarily replaced, but the problem continued with the overflowing. The original unit was re-installed. No voltage is detected at N-V, L-M or or L-H contacts, but voltage is at L-N.

Ice cubes are made if I manually turn the water valve on for ten seconds, and then turn it off.
