The circulation pump is used in both washers and dishwashers. In the washer, the pump is used to circulate the water during operation. In the dishwasher, the pump is used to drain the water from the dishwasher. If the circulation pump stops working, it will prevent the washer and dishwasher from working properly and will need to be replaced. This circulation pump is 120 volts, 60Hz and 30 watt and a genuine OEM part. Please remember to disconnect the power and water supply before starting your repair.
