Got the same fault on the same machine. As the dishwasher is draining there is a constant clicking in the base about once every 2 seconds. I’ve left the customer disconnecting their nice new plinth lights 👿 with wires running everywhere around the legs and not long enough to remove the plinth fully :rolls:. Any info on this would be helpful before I return as it’s a new one on me.
yes will be the alternating valve, it has a motor and microswitch which is what you can hear. assume the swtich is fut by a leaking seal on the valve. 819130468 is the part number. machine will have to come out to fit and you do not get the 3 o rings with it-re use the old ones. easy job otherwise £150 or so all in should cover it.
