    DIY Dishwasher Air Gap Cleaning

    You can flush out the dishwasher drain hose using the kitchen sprayer and then set aside to drain. Begin by flushing water through the holes in the air gap. Use a soapy sponge or a toothbrush to clean debris and build up from inside and around the air gap.

    Give the air gap a final rinse with clean water. Before reassembling, replace the old air gap washers with new ones. Doing this is an inexpensive way to ensure a good connection.

    With the new washers in place, replace the hoses and clamps into their original position, making sure to tighten the hose clamps. Once everything is back in its rightful spot and tightened down, run the dishwasher through a cycle to make sure that there are no kinks or blockages in the drain line.
