Customer Questions and Answers for Check Ball (Water Valve/Ice Maker) by Frigidaire

Bob, Are you sure you're getting enough water in the tub ? If the dishwasher is filling properly, there should be a t least a slight pause between the end of the fill cycle and the start of the wash cycle, and make sure the filters are not blocked. Here's some information that may be helpful : " The cycle starts with the check ball in the normal position resting at the bottom of the ramp covering the outlet for the upper arm. The outlet is not covered completely by the ball, some water does bypass the ball entering the delivery tube for the upper arm. The majority of the water leaves from the center opening, into the lower spray arm; washing is now into the lower rack To change the spray to the center, the control pauses the wash motor for not more then .6 of a second. During the pause, water pressure on the back of the check ball decreases, this allows the water located in the delivery tube to reenter the sump. The check ball is moved away from the opening by the returning water and is forced up the ramp. Now the wash pump restarts, this creates water pressure in front of the check ball moving it up into the center outlet stopping the lower spray arm. Water exits out the side outlet leading to the center arm and the upper rack. Water sprayed from the center spray arm sprays both into the upper rack and down onto the lower rack. At the same time, the shower nozzle in top of the tub sprays water down onto the upper rack. To return spray to the lower spray arm, the pump is paused for 3 seconds. This longer pause allows all of the water to drain back into the sump from the delivery tube and the check ball to fall back down the ramp to recover the side outlet hole. This completes the change cycle. This cycling between the spray arms continues in all wash and rinse cycles." Thanks and Good Luck
