Whistling Sound
When water is drawn into the dishwasher, a whistling noise can be heard. This is normal. If the water pressure is too high, it will be louder so it may be necessary to adjust the water valve to lower the pressure if the noise is too loud.
-
Rattling Noise
Rattling noises can be caused by improperly loaded dishes or a loose or clogged filter.
Ensure the dishwasher is properly loaded. Utensils hanging out of the rack can hit the spray nozzles or other dishes while a cycle is running. Moving dishes around in the racks so they are secure can prevent this from happening.
If the drain filter is clogged or has not been inserted properly, it can rattle or shake during the cycle. If the filter is dirty or clogged, clean it and reinsert the filter securely and try again.1Pause the cycle and check whether dishes or silverware stick out of the rack.
2Reload dishes and leave space between light dishes such as plastic plates.
