These precautions are intended for the personal safety of the operator, user, servicer, and those maintaining the machine. a DANGER Danger indicates an imminently hazardous situation that, if not avoided, will cause severe personal injury or death.
Section 1 Safety Information WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: • Disconnect electric power to the washer/dryer before servicing. • Close gas shut-off valve to gas dryer before servicing. • Never start the washer/dryer with any guards/panels removed. • Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the washer/dryer is properly grounded.
Section 2 Introduction Customer Service If literature or replacement parts are required, contact the source from whom the machine was purchased or contact Alliance Laundry Systems at (920) 748-3950 for the name and address of the nearest authorized parts distributor. For technical assistance, call (920) 748-3121. Nameplate Location Nameplate When calling or writing about your machine, be sure to mention model and serial numbers.

Section 2 Introduction General This frontload washer provides some of the same principles of operation as the typical topload washers. It senses water level, it dispenses the desired laundry detergent, agitates the clothes for good cleaning action, pumps the water out of the washer and spins the clothing in preparation for the dryer. The difference in operation is primarily the rotational washing agitation created for the horizontal basket and drum.
Section 2 Introduction How Your Dryer Works Cylinder Lint Filter Heater Duct Exhaust Fan Air Duct 505617 Gas Valve H179SE3A The dryer uses heated air to dry loads of laundry. When the motor is started, the exhaust fan pulls fresh air in through louvers at the rear of the dryer and over the heat source (burner flame for gas and heating element for electric). The heated air moves through the heater duct and into the cylinder, where it circulates through the wet load.
Section 3 Troubleshooting WARNING To reduce the risk of electric shock, fire, explosion, serious injury or death: • Disconnect electric power to the washer/dryer before servicing. • Close gas shut-off valve to gas dryer before servicing. • Never start the washer/dryer with any guards/panels removed. • Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the washer/dryer is properly grounded.
