Fault Diagnostics
Dispensers -- Customers using too much detergent, not using rinse-aid & not knowing how to close the door.
Drain hoses not installed properly --Often no air gap or high loop + pinched hoses -- causes poor draining & smelly dishwashers. Most drain pumps are mistakenly replaced for drain hose installation issues.
Outer doors -- Most are dinged during shipment.
Damaged water valves -- Primarily from fittings being overtightened. A damaged valve can allow some water onto kitchen floors.
Customer self-help diagnosing
Dishwashers may occasionally exhibit problems unrelated to a dishwasher failure. The following fixes can be made by customers without calling for repair.
Dishes do not dry -- The rinse agent dispenser may be empty. Check the rinse-aid dispenser and refill it if necessary. Dishware drying can be accelerated and enhanced by opening the dishwasher door slightly and propping it open with the top rack.
Indicator light(s) do not come on -- A fuse may have blown or a circuit breaker tripped. Check the fuse or circuit breaker at your fuse box/breaker box and replace the fuse or reset the breaker if necessary.
Dishwasher does not start -- The dishwasher door may not be properly shut. Make certain the dishwasher door is shut and latched.
Dishwasher runs a long time -- If the dishwasher completes the cycle, but the run time seems exceptionally long, it may be due to cold incoming water. Before starting the dishwasher, open the hot water faucet at the sink nearest the dishwasher. Run the water until it runs hot, then turn off the water and start the dishwasher.
Machine cycle does not advance to rinse -- The water supply line may be shut off. Check the water supply valve and open it if it’s shut.
White spots left on dishes -- More rinse agent is needed.
Water not pumped from dishwasher –
oMake certain the drain hose isn’t kinked, clogged, or improperly installed. Make sure the drain hose is at least 20 inches above the floor.
oMake certain the dishwasher filter system and kitchen sink drain aren’t clogged. You may need a plumber rather than a serviceman for the dishwasher. If an air gap is installed at sink, it may be clogged.
Detergent dispenser cover will not shut – The cover may not have been shut correctly or a cycle was not finished and should’ve been cancelled.
Streaks on glassware -- Too much rinse agent is being dispensed.
Rattling noises -- Utensils may not be properly arranged.
Suds in dishwasher – The customer may have used the wrong type of dishwashing detergent. Use only automatic dishwasher detergents.
