Installation

1.Open the dishwasher access doors and check the location and condition of the connection flange o-ring. Replace the o-ring if it is worn or damaged.

Place the upper wash arm rear guide pin in the rear support so the wash arm hangs in the support.

2.Slide the upper wash arm toward the rear of the dishwasher making sure the rear guide pin is centered in the rear supports.

3.Raise the front of the wash arm so the connection flange pin mates with the connection flange pin slots.

4.Swing the front of the wash arm up toward the front of the dishwasher.

The wash arm front guide pin should be positioned close to the door opening and before the front wash arm supports.

5.Slide the upper wash arm forward as far as it will go making sure that the front guide pin is above the front support notched cut-out.

Lower the upper wash arm so the front guide pin seats securely in the front support notch. Installation is complete.
