To repair a leaking dishwasher, start by examining the gasket for cracks, caked-on crud and wear. Replace it if necessary. For a dirty gasket without any serious damages, clean it with a brush and mild detergent. If necessary, adjust a latch plate to tighten a loose door.
For a dishwasher that does not start, check the power switch, and switch it on in case it is off. Check the power cord. If it is unplugged, plug it in. If the machine fails to start, check if the breaker has tripped at the main electrical panel, and switch it on. If the machine fails to run, wear gloves, and spin the motor fan blades by hand. Spinning the motor helps start the machine, especially if the dishwasher has idled for long.
When a dishwasher fails to clean dishes properly, clean the spray arm, the float switch and the valve screen. Remove the spray arm. Scrub the base and spray arm with a toothbrush to remove all grease and debris. Wipe off the dirt with a sponge. Clean the spray arm holes by poking them with a wire to remove debris. Remove and clean the float switch with a toothbrush and sponge. Then, disconnect the power and water supplies to the dishwasher, and remove the door's lower panels, supply tube and electrical wires. Remove and clean the valve screen, then reassemble the parts.Learn more about Dishwashers
