After making sure the dishwasher trays are sitting within their holdings properly and the noise has not been caused by this, examine the runners and racks. If the fasteners that hold these parts in place have come loose, it could result in movement that should not normally occur during the cycle. Rectify this by tightening or replacing the screws as necessary.
It will also be necessary to check the spray arms to make sure they are working correctly and can move as they should. Use a screwdriver to remove them if necessary.
The reason for your dishwasher creating a noise may be the simplest one. Begin the process of troubleshooting dishwasher by checking the inside for any food remnants that may be loose in the machine. Items such as particles of bones and seeds can often be washed away from dishes to roll around the machine and clog up the mechanisms. Check the dishwasher and clear away any particles that you find.
Troubleshooting dishwasher will involve checking the motor to determine whether this is the cause of the noise. If any components of the motor have come loose, worn out or are defective, a rattling noise can result when the dishwasher is switched on. If a defect cannot be fixed or parts are worn out, the motor will need to be replaced to rectify the problem. If you cannot find any other reason for the noise, it would be prudent to replace the motor. Be aware that they have a limited life so are likely to need to be replaced when they reach a certain age.
Checking the heater fan will need to be included in troubleshooting dishwasher process as the moving parts can be noisy if they have become dislodged. Check for any signs of rust as well as any loose fasteners as both can result in unwanted squeaks and rattles. Use a wire brush and/or lubricating oil to rectify the problem or replace the relevant parts.
Check the pump in the troubleshooting dishwasher process as this is where debris can collect and cause noise when the dishwasher is working. Clean out the pump and test the dishwasher to determine whether this rectifies the problem.
Wear and tear can affect every part of a dishwasher and if this extends to the water inlet valve, it can result in it coming loose and shaking enough to cause noise. In addition, when the problem is a significant one, it can cause the valve to switch on and off of its own accord which will not only be noisy but will stop your dishwasher from working properly. The inlet valve is normally located beneath the access panel of the dishwasher and should be checked to determine the state of repair. It should be replaced if it is showing signs of wear.
