1. Sometime I hear a squeal from the machine. What is happening?

This squeal is actually “standing waves”. It usually means the liquid is trapped with air bubbles and the water detergent has not “degassed”.  Increasing the temperature or changing the liquid level or adding additional detergent all contribute the liquid “degassing”.  Typical degassing time is approximately 10 minutes with detergent in the tank, ultrasonics at full power, and the pump off (if equiped). The squeal does not damage the machine it is just annoying.
