Can I run a cycle with the water off

Frigidaire FFLE3911QW . The winterizing instructions say turn the water off etc. Run rinse and spin cycle. Add RV antifreeze. When I turn the water off , I cannot run any cycles and get 3 beeps. Someone online says the machine wont run with the water off. Frigidaire tells me it should, call a tech. Does anyone know if it should drain with the water off?
