Section 3 Theory of Operation Starting the Machine Drain The door lock will not allow a cycle to be started until the door has been closed. Standard models include a normally-open gravity-type drain system. When the drain valve opens, the perforated basket allows water to drain from it. A pump drain is available as an option on the smallercapacity models. Fill The operator selects a cycle and starts the machine. Water enters the machine through water valves that are controlled by the microcomputer.
Section 4 Troubleshooting WARNING To reduce the risk of electrical shock, fire, explosion, serious injury or death: • Disconnect electrical power to the washer-extractor before servicing it. • Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it. • Never start the washer-extractor with any guards/panels removed. • Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the washer-extractor is properly grounded.
