If the pump on your Vitapur VWD1006BLP bottom-load water cooler has stopped working, here’s a step-by-step guide to troubleshoot it: 🔧 Basic Troubleshooting Steps Check Power Supply Ensure the unit is plugged in securely. Verify the outlet is working by testing with another device. Reset any tripped circuit breakers. Inspect Bottle Placement Make sure the water bottle is seated correctly with the probe fully inserted. If the bottle is empty or not properly punctured, the pump won’t activate. Prime the Pump Remove and reinsert the bottle to reset the suction. Listen for the pump motor — if it’s silent, it may not be receiving power. Clean the Probe and Tube Mineral buildup or debris can block water flow. Remove the probe and clean it with warm water and vinegar. Check Float Switch or Sensor The unit uses a float switch or electronic sensor to detect water levels. If this sensor is dirty or malfunctioning, the pump may not engage. Inspect for Leaks or Cracks Look around the pump housing and tubing for any signs of damage.
