I’ve a fitted Whirlpool ADG7540 dishwasher. Of late it has produced a rumbling sound when in its cycle. It’s the sort of sound that I would associate with the spin-arms spinning eccentrically (i.e. come loose). However I have had these out and cleaned them through and reseated them OK per the handbook. Nothing else seems loose inside.
Otherwise the machine is working perfectly.
Anyone got any ideas ?
Deliberately jam the spray arms in turn to stop them rotating and run it empty on a rinse only (no heat cycle) to eliminate them, it’s probably one of them though 🙂
