Zannussi dishwasher dead

Is there a thermal fuse on the control board?

thanks

The one thing that I maybe should have done, with hindsight, was to have measured the resistance between L&N on the plug pins, but , again, without a reference it would be pretty pointless. If I got a resistance value other than infinite, it would indicate that the there was no neutral break on the mains lead - but I have never seen a lead damaged other than on potable appliances as the cable enters that appliance.

No that could also mean there was no break on the live cable in the mains lead and if you got infinite resistance that could mean there is a break in either the lead or SOMEWHERE inside the machine , which you know anyway as you have no power[/QUOTE]


Which is pretty much what I said. And without access to wiring diagrams, knowing that there MAY be a break in the neutral inside the machine is worthless.

On a boiler, one if the checks to prove a fault on a component is to check the wiring harness serving that element, which is what \i thonk you are driving at.[/QUOTE]

No it's not!

Look if you are not going to take our advice and seem to have your mind set on how you want to fix it even though your way is not possible because you don't have access to a wiring diagram then we can't help you.

As for a thermal fuse? No idea , have a look you seem to know what a thermal fuse looks like and whilst you're at it why don't you check for power to that board?

I have little experience on dishwashers but if you follow a logical sequence you can eliminate several things even without the info you normally use on a boiler. If you are using a multimeter & measure 230/240v at the lead where it enters the machine ( probably connected to some form of suppressor) check between live & neutral & live & earth. If your input there is ok then check the output from that component. From there the power should go to an on/off switch on the machine facia, make similar checks there. If you have not found the problem by then the only other thing I know about dishwashers is that with a drop down front that has the controls built into it then there will be a harness at the bottom of the door joining the front panel to the machine & with flexing, broken wires in this harness is a common problem.

I must have missed the bit where you offered advice, as opposed to a sarcy comment.

That wasn't a sarky comment , you have not listened to anybodies advice (including mine)

Two people now (including me) have told you where you need to start, the fact that you are not listening to said advice makes me wonder why you bothered posting

I'm out

You clearly cannot read. There was power in the appliance. If you wish nit to help, then fair enough - but why be a dick over it?

 

[FiremanT]

Did the machine show any signs of warning before it died on you? Did it make any weird noises?

No. It is my daughters, so was not there, but they said it was dead when they went to use it. No issues before hand, although it was never brilliant at its job.

Thanks

My daughter has the above. It suddenly stopped working- no lights at all showing.
I got the front cover off, hoping to see evidence of a failed board but nothing obvious.
You can get pretty much any gas boiler circuit diagram and fault finding help, but cannot for dishwashers.
Can anybody help?

thanks

Hi, I know it's been 5 years since you had the problem. Mine did exactly the same with no lights. There is a PCB in the main control panel with switch mode PSU. In my case it was a IC that failed and took a resistor with it. The IC is commonly used in washing machines, dish washers and so on. It's LNK364GN and when it fails, it shorts drain and source causing the direct short pos to neg on the 48Ohms (10%) resistor. I have replaced the IC, resistor fitted was 47Ohm 5W 1% and the 22nF capacitor that was affected too. Hope this will help others with similar failures as I have just saved £450 on a new dishwasher. Parts cost was around £10 and my time to fault-find and repair... Best regards all (except sircerebus666)

Thank you for your, albeit a bit late , response.
Hopefully, it may help someone on the future.
In the end, I removed the machine and re-hashed the door to create more storage space. It was quite a small unit anyway, and the storage was more welcome in the starter home kitchen.

Happily, my SIL’s career has taken off, and my daughter returned to work as the kids got a bit older - so now live in a bigger house with a bigger dishwasher

Perhaps some other contributors ought to learn how to conduct themselves.

Thanks again

That's my idea to help another kind person who comes across the same issue un the future.
I hate failed appliances going into a landfill for the sake of a few quid.

This particular circuit (and many more in other appliances) is just on the threshold of its limits and has been designed to fail! Could have speced the components to a higher voltage but then they wouldn't make a profit if white goods lasted 20 years+
