I have an ISE W1607W, which a few years ago failed to power on. It turned out that the issue was caused by a failure in the power board, this was fixed with a new LNK362PN and 2W 2.2Ohm power line resistor.
Yesterday the machine wouldn’t respond to the start or open buttons, nor some of the other selection buttons, although you could cycle through the different programs and various lights would indicate temperature, spin speed and time for cycle.
Long story short, I have removed the control boards and have found black carbon, smoke, marks on the back of the start/stop and door release buttons plus around some surface mount resistors and capacitors on the control PCB.
I cleaned the board up so that I could see what components had blown. It would appear that 3R22, 3R23, 3C16 and 3R9 have failed along with the PCB track leading to them (circled in the picture).I suspect the same fault as before but this time around the power resistor didn’t blow but these components did.
Does anyone know what values these components might be or where I can find out?
Failing that does anyone know of a supplier for the control boards that can ship to the UK? (Entire assembly is labelled Invensys ASKO WM70.1 8088613-01)my worry is what has cause this
follow the current path to the next board in line and look for more damage there
dont think there are many parts available for these now, if at all
but we can ask a few people once we know the extent of the damage

The board listed in the shop here is a whopping £250. I strongly suspect that even though still listed it will be NLA. The original manufacturer of the ISE, a company called ASKO was taken over many years ago first by Italian manufacturers Antonio Merloni, then later by Slovenian firm Gorenje who in turn were swallowed up by Chinese company Hisense. All this upheaval does make parts for older appliances very sketchy to say the least. Whilst there should be a full wiring diagram under the lid we never had any board level information at all. As Dave has already suggested this sort of fault is usually as a result of failures elsewhere.:(
Thank you for your responses. It seems a shame that mechanically sound machines should be let down by their electronics. The failed PCB components that I have noted so far are cheaper than the postage and so just a matter of pounds in total.
I have reached out to ASKO asking for information and had found a Gorenje board listed through the Hisense website but am awaiting feedback.
I suspect that other components may have been damaged, for example, the components that have burned out on the PCB are in the supply or return to the thermistor. A check shows that this is exhibiting a higher resistance than detailed on the diagram that comes with the machine. This leads me to suspect that there may be other possible failures.
If I can get information on components then I may attempt a repair but the cost of a control unit plus other components may make a repair uneconomic.
A bit of a long shot but as the visible damage is near the door release button you could check the door interlock for any signs of failure.
Looking at the wiring diagram it’s not obvious but I suspect the wiring from the three terminal pcb edge tag may go to the ntc/ thermistor. This was clipped to the side of the outer drum on most models and occasionally suffered from water ingress. Again a long shot but worth checking out.:)
Do you have access to the full service manual?
You’re correct its the connector for the thermistor.
The only documentation that I have is the user manual and the diagram found within the machine that shows what components are connected to the control board.
It shows a resistance range for the thermistor, but having measure it I think that I need to replace it, it reads 15.6KOhm which is outside of the expected range.I have had a reply from ASKO, they seem to think that Gorenje unit G436857 Control Unit Servis WM70.1C is applicable. They have it in stock, although a search on http://www.gorenje-spares.co.uk lists it a £802!
May be to late for you but if you let me have your email address via a DM I will send you the manual.

I have managed to find a UK supplier with both thermistor and Gorenje control board for under £250 and having convinced my wife that we can wait until Monday am willing to give it a punt so a service manual would be very useful.Link to manual sent. Would be worth pulling out the thermistor and having a look at it for any signs of water contamination.
Thank you.
A quick scan shows that the Thermistor reading that I took equates to a temperature of 0o Centigrade. I’ve ordered a new one and so will probably fit that, as the machine definitely isn’t in a room at freezing point, but it would be interesting to check its value range against temperature.
I’ll also have a look for any signs of water leaks. I’m not aware of any at the moment, but I guess a minor leak may not show, especially if it drains out of the back of the machine.
If there’s any sign of leaks from the drum assembly itself then I’ll return the new parts and scrap the machine.
I’ve no idea what I’d replace it with these days, when I bought it it was a toss up between it and Miele, but even though they still rate highly their warranty period has reduced dramatically since then.Machine is now fixed.
For future reference the following Gorenje parts were used:- Gorenje Control Module – Control Unit Service WM70.1c – 436857
- Hisense Gorenje Temperature Sensitive Resistor – Temperature Sensor Assembly – 440248
The power board of the Control unit has changed slightly. There is a new power switch control section so that the power switch is now a press and hold to switch on and off, plus the machine automatically switches itself off when the programme has completed.
