Oven doesn't give steam but it does reach the temp.how can i fix that?

First locate the water solenoid valve. Disconnect the water line to the inlet side of the valve to make sure water is getting to the valve. Once that's verified, disconnect the outlet side of the valve. Activate the steam and verify that the valve opens and there's a good amount of water coming out of the valve. If no water comes out. Verify that the coil is getting energized with the correct voltage. If the correct voltage is present and you have no water coming out. Replace the solenoid. If everything is working then remove the left panel inside the oven to check for blockage in the steam manifold. The manifold consists of a pipe with several spray nozzles that spray water on rebar. Remove all the nozzles and activate the steam. Do this several times to purge any rust or debri. Clean the nozzles and replace them. You should be good to go.
