Subject : Rattling Noise
Symptom
■ Rattling Noise
Cause
■ Most noises coming from the dishwasher are a normal by-product of operation.
The most common causes are food passing through the system, improper installation, or restrictions to water supply caused by buildup in the dishwasher.
How to fix
1. Check if the filter is loose or clogged.
■ The first 45 seconds of any cycle is an automatic drain. It is normal to hear some humming sounds and the sound of water
draining.
■ Check if the filter is loose
■ Remove the filter and feel inside the filter housing for anything caught that may be rattling.
■ Clean the filter.
■ If the filter was loose or clogged, clean thoroughly and reassemble the filter making sure to secure it firmly.
2. Check the noise occur during the wash stage of the cycle?
■ Dishes may rattle during cycle under the pressure of the water or if the spray arms make contact
with any items in the racks.
■ Make sure utensils and other dishes are not high enough for the spray arms to make contact.
■ Rearrange dishes or adjust the upper rack to accommodate tall or large items.
■ If the filter and drain hose are secured and there do not appear to be any items inside the dishwasher rattling, perform a
maintenance cycle to flush the system of any debris that may be rattling inside the sump assembly or drain hose
■ Leave the dishwasher empty. Use a dishwasher cleaner or place a cup of vinegar in the bottom rack of the dishwasher.
