Fault code recorded?
Check for loose objects in the drum, and run it empty to isolate the clicking from clothes tumbling noises. Note that the drum baffles are not removable in case something has slipped under/into one of them.
Run it on Air Dry to check if the clicking still occurs without heat. If so, check amperage or current on the elements to determine if relays for them are flipping on/off.
Run it with the top deck raised or the front panel removed (advise to lower the top deck into position so the side panels are stablized without the front panel) to perhaps help pinpoint the location of the noise if it's mechanical.
Edit: If not, check amperage or current on the elements to determine if relays for them are flipping on/off.[this post was last edited: 7/25/2021-14:26]
