Dishlex DX302 : Water not heating

Our machine is not heating the water. I have confirmed that the heater unit has a internal resistance of 26ohms and is getting 240v on the active side. However it is only getting 85v across it's active and neutral that goes back to the control board. I am guessing that the control board needs replacing as the resistance from G5 to G6 is only 2Kohms instead of the 6Kohms as mentioned in your previous post.

I was hoping to get a copy of the wiring diagram to confirm, before having to purchase a new control board.

    Hi



    Thanks for the advice, in the intrim I had replaced the control board which fixed the problem.

    Hi I also have no hot water and 26 ohms on the heating element and think maybe that I should replace the circuit board

    Yep, same problem. No heat. I put washing dishes way up there with watching grass grow so I'm pretty keen to fix this problem.

    Could you send me the Service manual and circuit diagram for the Electrolux DX302.

    Thanks

    Hi FixyaI also have the same issue heating /drying not working on Electolus DX302, I have attempted to remove the controll board and have not been able to get the board out of the casing once it was opened up, so do not know if it is just the dry solder joint or not .Is it worth buying a replacement controll board ,,,is this possible,thanks for the threads and help.

It sounds like the control board is faulty. have you checked for dry solder joints on the control board? also it is important the check the resistance of the taco on the wash motor. last of all don't worry to much about the 2k ohms of the temp sensor as it can vary lots depending on the temperature.
if you give me ur email i can send you the service manual and wiring diagram.

Hi

mine had this exact same problem - it turns out that the relay on the control board had not been soldered on properly. mine has shorted out over time, and caused a lot of charing of the localised area. i checked the relay, it was okay, so have resoldered the board and all is working for now.

i called Electrolux - 1800 001 218 - to report the problem, as i believe there are too many peoplew reporting this issue for it to be a one off. i was also concerned about a fire risk, as the charing on mine was considerable.

too be blunt, Electrolux didn't seem to care too much, unless if i wanted to pay to have someone come look at it, despite the fact that i am an electrician.

Electrolux currently say that this is the first time this problem has been reported - despite that fact they are aware of this thread. i would encourage anyone whoi has this fault to call the above number and report your problems to them, as i believe a recall may be waranted, and, should your unit have serious problems (fire) it is on record.

Electrolux currently have a recall on a couple of other dishwashers due to the fact they pose potential fire risks - see www.recalls.gov.au

    Dishlex 302

    Usual problem - not heating / drying.

    Check back of computer board. A solder seems to have burnt out / off. Resoldered and now working again. It's a worry that the first one melted or burnt off though.

    Something wrong with this setup.

    Cheers,
    A.

I have had a similar problem and yes, the problem is the load side connection between the power relay and the circuit board. I have resoldered it and laid over that part of the board circuit, heavier wire to reduce local heating. Unfortunately, the problem arises again from time to time.
It's just a very poor piece of electrical design !
I believe the only permanent solution is to insert a secondary relay between the circuit board and the heater feeder wire in order to reduce the current (and hence potential to overheat that section of the circuit board. I am considering fitting a relay with a 240 volt ac coil but to simplify wiring but need to get a wiring diagram in order to arrange the neutral side connection for the pull in coil.
A circuit diagram would be VERY helpful.

My bocsh 830es water heater will be running normal then will kick into a A3 mode no more hot water


Check for a green wire near the top right of your machine. It would loop back to itself with a little black heat shrink on it. This should be far away from the heat exchanger. if its near it, I would recommend pulling it out of the wire clips, and relocating it to behind the control unit on the right side of the machine. Keep it away from heat....its a resistor, and will pop random A3 codes if the heat increases its resistance. Reset your code and you'll be good to go.

Doubble check the settings on your machine.

It is a long way from my heater to the washer. Hot water is essential to the operation of any model machine. I always get hot water to the sink (by running the hot water, of course) before I start the washer. I can tell when I fail to do this.

Just a thought, I hope this aids your situation.

Of course your washer heater may have failed ... You can check it using a volt/ohm meter.

Thanks for your question this morning @ FixYa.com

Dishlex dx302 - not heating water


If it is the old model about 15 years old (i own one myself) it is the water inlet it may be leaking.

I had the same troubles and i installed a new pipe on the dishwasher and now it heats fine. All you need to do is get a new pipe (you can get them from the dump) off of an old dishwasher and put it on yours but make sure it doesnt leak first.

If you have more questions please dont hesitate to ask im more than happy to help

Water not getting hot


there is no thermostat but there is a temp sensor (ntc probe). if you check the Resistance between terminal g5 and g6 you should get 6.03 k ohm at 20 degrese Celsius.
it sounds to me like the control board needs replacing.
i can send you a wiring diagram and full diagnostics in pdf format if you give me an email address

Dishlex dx 302 heat drying


Found I had no hot water in my Dishlex DX302 and did a google search and found this page.

My problem was found to be the same as the others; one of the solder joints on the relay on the control board had arced off.
You could see the burn mark on the board and cover where it had been arcing.

Soldered it back together, and now it seems to be going good again.
Now my only problem is a damaged door seal, which means a small water leak; I have used part of a rubber glove to bridge the gap, and it reduces the water leak.
