This dishwasher has been turned off, with the water supply valve under the sink also off, probably for some time. After turning the supply one, running water could be heard. When trying to run a wash cycle, it whirrs briefly, then clicks rhythmically for about 10 seconds, then repeats this a few times, then plays some beeps and displays the error code F4 E4. I believe F4 means there is a problem with draining, though I don’t understand what the problem could be given that there was no need to drain the empty machine. I tried pouring some water into the tub so there was something to drain, and after failing to do anything, this water is pumped out with just a little left in the bottom under the filters. I haven’t been able to gain proper access to the innards under the dishwasher so haven’t checked much. However, disconnecting the supply hose from the water pipe shows that the screen there is clear. The outlet at the bottom of the tub is clear, as are the coarse and fine filters. I could not find a float while poking around to see if it is stuck.
This was caused by a faulty (rusted) circulation pump. What little evidence there is on the internet suggests that F4 E4 indeed means exactly that the circulation pump is not working, but there are multiple causes: it could be to do with wiring, the main board, or the pump itself as in my case. While I haven’t got the machine fully working due to time limitations, with a replacement pump it was able to run a rinse cycle which before was not possible. A new pump is quite expensive (about £100) but I was able to get a second hand one for much cheaper. Some notes if anyone else is working on this or a similar machine: performing this fix would have been impossible without pulling the machine out and resting it on its side. The pump (and other components) are installed with ear clamps on the hoses so you need decent side cutters to get them off, and replacement hose clips. The hose for the pump is moulded and has recesses for the clips so try and get the right size (I got something a bit too big and it seems OK) The time delay has been chasing leaks from other parts that I pulled out in case they were the problem but were not.
Hi, Don’t know the dishwasher but how much water is filling into the dishwater? If there is not much water being filled into the dishwasher it has a flowmeter which may be the cause of the problem. Assuming that it performs the same function as in my dishwasher that is;-) I had a similar problem with my dishwasher (not same brand but similar symptoms, would try to fill and then stop) because the flowmeter was faulty. This registers the water flowing into the dishwasher and because it did not “detect” it, the water inlet solenoid is shut off and the machine is stopped to prevent possible flooding in case the hose etc was damaged. The dishwasher has an optical water level switch which reading the description maybe would give the error code if it thinks that there is still water but it is not. Also the error codes that you mentioned are not shown in the user manual, as a drain hose problem may be a F6 E3 or a F8 E1 Just some thoughts.
