Hi guys, I have a zanussi FX1465w XC6 that was left by the previous home owner. When we moved in it did not work, when selecting a program the door interlock would just click but never lock and then the machine would beep three times at the same time as the end light flashing 3 times. Being the meddling type I fiddled round with the interlock and got it working, the machine worked fine for 3 months when one day it blew the main house RCD. When I switched the power back on the machine just started beeping three times whilst flashing end three times, upon inspection two tracks had blown on the PCB, one which goes to the door interlock. I ordered a new interlock and repaired the blwon tracks, however at first it still did the same 3 beeps/flashes, then suddenly it worked then it didn’t again and returned to beeping/flashing. I assumed that the PCB must still be at fault, luckily I managed to source a dirt cheap PCB with the right part number and configuration for my machine. Didn’t solve the problem, now what happens is you turn the machine on, the start light flashes as normal, however if you then press it the door locks but then the end light begins flashing 3 times with 3 beeps. Even more odd if you turn the machine on but do not press the start button after 10 seconds the door locks and then the lock starts cycling every few seconds and the 3 beeps/flashes happen again. So far I have tried disconnecting the heater element and I have checked the pressure valve pipe and cleared the filters out, the drain pump runs fine. I have also tried to get the error codes to flash but the machine will not enter diagnostic mode, holding start/pause plus one other button and switching on results in the same behaviour described above, I do not get the scrolling LED’s. When the machine was working there were no problems with spinning or draining.

Sure, I would go straight to the motor and the heater and test both for insulation problems. Either, or is your problem I reckon. 😉
Re: Zanussi FX1465w XC6 problem
Cool thanks for the help, I have tried disconnecting the heater element surely that would eliminate that part from the equation?. I have not tried disconnecting the motor however, I will give that a try next, if disconnecting them is not sufficient I will try and get someone to put a meggar on it.
Re: Zanussi FX1465w XC6 problem
Ok so I tried disconnecting the motor to eliminate a ground fault, still exactly the same. This got me thinking so I unplugged everything from the PCB except for the main power lead, turned it on and guess what? same thing happened. Start light flashes for 30 secs then goes out door lock cycles and then end light flashes 3 times accompanied by 3 beeps. Now normally I would conclude that the PCB is at fault however the PCB is a)brand new b)not showing any sign of damage or blown tracks or components c)it is displaying the same problem I had with the previous PCB. So it seems to be something in the machine causing the problem but what elese is there?, I unplugged everything from the PCB apart from the power supply. The only thing the power supply goes through is some sort of capacitor, could this be at fault? It almost seems like the machine times out, if you press the start button when the machine is fully wired up it will take on water for ten seconds and then suddenly shut off, then the beeps/flashes re-appear and the drain pump runs.

What you must also take into account is that the PCB stores the previous fault in its memory. Therefore the component that created the fault must first be rectified in order to ‘reset’.
Also, it is essential for all components to be connected at the start of any new programme selection. The PCB then ‘self checks’ all components prior to starting. If a fault is detected by the PCB then you have a problem……
Hence my suggestion to check the motor and the heater while you’re at it! 😀
Re: Zanussi FX1465w XC6 problem
Ok I am with you, so the PCB could have detected a fault when I first fitted it and now even with everything disconnected it still thinks the fault is present?. What I don’t understand is why my machine will not enter diagnostics mode and flash the error code, has anyone seen that behaviour before? surely if the PCB is detecting a fault I should be able to read the code?. Cheers

As a general rule yes, but intriguingly, not always. Such is the joy and wonderment of modern electronics, in that they don’t always play up to the set ground rules. 😕
Best of luck! 😀
Re: Zanussi FX1465w XC6 problem
Ok I guess that makes sense, I usually spend my time diagnosing faults on my car and that too often does not display an error code. I am still a little stumped as to why it will not enter the diagnostics mode, even if there is no error code logged I would expect to be able to enter the diagnostics mode. However holding in the start/pause button plus one other option button and turning the dial one click clockwise does nothing, no beeps and no scrolling LED’s. Everything I have read suggests this is the correct way to enter this machine into diag. mode.
Re: Zanussi FX1465w XC6 problem
Haven’t got hold of an insulation tester yet, went round the machine with a multimeter meter though. Didn’t find any broken wires, heater element is reading 30ohms, drain pump 170ohms. I didn’t detect any leaks to earth on the motor or heater but I am well aware that they may only show up under a high voltage test.
