The brand was sold to Electrolux and the Gibson dishwasher line was discontinued. Electrolux and many parts suppliers still carry parts for the Gibson dishwasher, so DIY repairs are possible. Troubleshoot the dishwasher before paying for parts or repairs to make sure they won't cost more than a new, more efficient machine. You can troubleshoot a Gibson dishwasher in the same manner as many leading dishwashing brands.

Set the washing cycle for a longer cleaning period to remove stuck-on foods.

Rearrange the dishes so the items are not too tightly packed. Leave some space between the dishes to allow the machine's spraying arm to reach them.

Check the water pressure and heat by unhooking the water supply and attaching a water-pressure meter. The water pressure should be between 20 to 120 lbs. per square inch (PSI). Check the water temperature with a thermometer. The temperature should be 120 degrees Fahrenheit.

Inspect the funnel above the top rack for clogs. Clean it with a clean towel.

Water problems

Test the mineral content of your water using a water hardness testing kit. Hard water can cause the dishwasher not to rinse the dishwasher detergent properly off your dishes, leaving spots. If the test reveals you have hard water, put a rinsing agent dispenser in your dishwasher.

Place a level on top of the machine to test whether it is level if there are leaks. Adjust the legs of the machine by unscrewing the feet at the bottom by hand.

Inspect the drain at the bottom of the machine if water pools after the washing cycle. Remove any debris by hand. Remove the drain hose using a pair of pliers and remove any debris from the hose.
