Hi,
Our ISE10 – a 1406W / Asko WM25.3 – from early 2008 has stopped heating the water. There are no error codes, we just noticed that the clothes weren’t coming out clean. On investigation, the water remains cold and there is no voltage across the ‘EL’ terminals on the programmer at the times when I think the machine should be heating. The thermistor tests ok, and there seems to be a suitable resistance when testing the element down the wires which plug onto those terminals, indicating that the pressure switch (through which the element wiring passes) and wiring are ok too.
So my immediate jump at this stage is to the control module. But am I missing something?
I did consider the possibility of repairing the module (if that’s where the problem lies) and was hoping to have a look at it but, late last night, I wasn’t readily able to remove the controller from the inside of the front panel – the plastic tabs which look like they should be levered to one side to release the clips mostly seem to have extra stiffeners on as if to prevent this. So at that stage I just put it all back together.
It may or may not be relevant to note that the machine appears to have been leaking for some time, due to the presence of considerable rust on the bottom tray. The thermistor was wet when I removed it for inspection. I suspect that the bearing seal is leaking; there are no obvious run marks from higher up, and it certainly seems to be at the back. There is also some rust at the front/left/top where there is a tiny gap between the two halves of the soap container which evidently allows the steel to be wetted regularly. I don’t think this is significant.
Any advice would be gratefully received. I really don’t want to scrap such a good machine before its 9th birthday, but at the same time, I’m not sure whether I can bring myself to spend ~£250 on a new module.
Thank you,
Jon.
Re: ISE1406W not heating water
PS – I feel foolish now to have found this post:
where the OP describes very similar problems. I think it’s highly plausible that we are guilty of overloading the machine (though probably not oversoaping). I’ll try to get it properly dried out and see whether that affects the heating. Then see if further sealing is also required.
If anyone thinks other advice would be relevant, please feel free. Oh, but not ‘search before you post’, please – I’m embarassed enough about that already.
Re: ISE1406W not heating water
Just wanted to post an update on this.
While the resistance measurements for the thermistor (when dried) were plausible, they didn’t seem particularly stable or predictable so I fitted a new thermistor to be on the safe side, it being an inexpensive part.
I left the top and rear panels off the machine for a couple of days and gave it periodic bursts with a fan heater directed at the drum to dry it out thoroughly.
I cleaned up the hose and breather from the soap drawer where they enter the drum and refitted them using silicone sealant. There was extensive limescale residue running down the outside of the drum from the hose which I hadn’t seen at my first investigation because of poor light on that side of the machine – my mistake. This water was landing on the collector tray under the drum then running to the back, hence the appearance of a leak at the rear.
I left it a day for the sealant to go off then I ran the machine a couple of times without the top or rear panels on and wasn’t able to observe any leaks.
The first cycle I did was a 95 degree white cotton wash. I was surprised to find that it didn’t begin to heat the water until about 15 minutes into the cycle, but it did heat the water such that the glass was too hot to touch comfortably. It did however trip our RCD part way through heating. I reset the RCD and a couple of minutes later it tripped again. Then I ran an extension lead from a non-RCD protected socket (don’t try that at home, kids) and the cycle completed fine. I’ve done a few 40 degree loads since then which have all been fine; the glass gets warm and the washing comes clean, and there has been no more tripping the RCD. Time will tell whether tripping becomes a problem on certain programmes/temperatures, but hopefully it was an anomaly. If anyone has any other suggestions though, I’d be happy to hear them.
So the good news is that there doesn’t seem to be anything wrong with the controller. 🙂
I also put a bit of silicone near the front of the soap container, in an attempt to prevent the corrosion getting worse up there.
So it seems like we’re back in action, and we’ve even cleared the backlog of washing in time for Christmas. 🙂
Thanks,
Jon.
