Heat pump tumble dryer

Test mode on Aeg, Electrolux, John Lewis, zanussi heat pump Tumble dryers

It is very difficult sometimes to diagnose the problems with these heat pump tumble dryers.
I have included a video to show you the test mode sequence and also a PDF below which I managed to obtain.
but whenever you need parts for these dryers you will need to quote your model number and also the PCN number before we can do that you to the correct part

if you are still having trouble please contact us using your full model number including the product number for help from Paul

 

Finding your problem with a heat pump tumble dryer can be difficult on occasions as these tumble dryers dry the clothes using Refrigeration process.

These are some of the common error codes or faults

All dryers will show the alarm code on the time to end display.

The alarm will be shown as EX Y e.g. E51E = ErrorX = alarm family Y = alarm number

Safety first! Unplug the machine from the electrical supply and make sure the machine has been idle long enough so that the heater has cooled down.

 

Once a year vacuum the inside taking special care on the wiring, it is very important to clean all the vent tubes on a regular basis. Clean the heat exchanger (condenser dryers only)

We hope this tutorial helped you get your tumble dryer working again!

    Hello Paul!
    I will start by saying, thanks a lot for the help and the instructions you give.
    I have a very similar tumbler like the one you stripped down and showed us how to get into service mode. Mine Is a six years old Husqvarna QW9281 no 916 097 136 00. And my problem is it won’t dry our clothes. It seems that the machine don’t heat any more. It stops after an half hour and it is wet and just a hint of heat. I tested it liked you showed and got this error code E32. Have you any advice?
    Cheers

    Hi Paul and good afternoon to you,

    I have a JLTDH 16 made by John Lewis.
    I don’t get any water back to the water dispenser, hence the clothes aren’t drying correctly .

    I have cleaned out all the filters and i have gone into the test mode and on,

    C2 it comes up with 111

    C 8 COMES UP WITH E 32

    C 9 comes up 111

    C 10 comes up with E 32

    I se on your error codes that E 32 is Conductimetricsensing oscillation frequency.
    too low.

    To a layman any pointers to what can be wrong, if so is it expensive for the part the tumble is 6 years old,

    Thankyou so much for tutorial on your web page i found it so interesting,

    Best Regards Bill

    Hello, I have a Bosch WTW85490GB Heat Pump Tumble Dryer and the Dryer is not collecting water in the tray. Do you have the equivalent Diagnostic sequences which you showed on the AEG/John Lewis model for the Bosch machines? That would be exceedingly helpful and would in return like to buy you a Beer! Thanks Howard

    Hi. I have a Candy model CS H8A2LE-80/ heat pump dryer. I bought it new and it came with a one year warranty. Shortly after the year elapsed the dryer appeared to malfunction. There is a tank attached to the door that collects the moisture/water from the clothes as they are dryed. What happened is the water was no longer being sent to the tank. My first thought was that the line from where the water accumulates to the tank was clogged. I removed it and checked it. No clog whatsoever. After further research I figured the pump that sends the water to the tank had died. I ordered a replacement and installed it. Made no difference. What I’ve been doing in the meantime is still using the dryer. If I take the clothes from the washer after a 1500 rpm spin cycle and hang them on a line for a few hours, most of the dampness seems to dry. I then put the clothes in the dryer and run it like I did before. The dryer gets warm and does eventually dry the clothes, but still no water collects in the tank. It does, however seem to me the room where this is taking place is becoming quite humid. Well, after all, the moisture has to go somewhere. So…….it appears I have a dryer that works at removing the dampness from the clothes but, instead of collecting it in the ‘staging’ area to send it to the storage tank in the door, it just gets sent through the exhaust vent into the room. Could you please steer me in the right direction as to how I can sort this? Thank you in advance! 🙂

    Hi Paul
    I have an AEG LAVATHERM 8DEC946R Tumble Dryer and am experiencing a small amount of water appearing under the condenser which can be cleaned up with a tissue. There is no fault code appearing but as this has not happened in the four years, we have owned the dryer I am wondering if I should call out an engineer to repair the dryer if needed while it’s still under warranty. The condenser has been regularly cleaned and this has only become apparent recently.
    Regards
    Tony
