Heat pump tumble dryer – finding faults and error codes

by / Friday, 16 February 2018 / Published in Repair Guides

Finding faults and error codes 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. E51
E = Error
X = alarm family
Y = alarm number

Alarm

E21 - Tank drain pump triac failure.
E22 - Tank drain pump triac sensing failure.
E31 - Conductimetric sensing oscillation frequency too high
E32 - Conductimetricsensing oscillation frequency too low
E51- Motor triac failure.
E52 - Motor thermal cut off.
E53 - Motor triac sensing failure.
E54 - Motor jammed
E61 - Heating timeout
E62 - Compressor relay failure

E95 - Communication error between microprocessor and external EEPROM
E97 - SCF –CTF mismatch error
EB1 - Power supply frequency out of limits
EB2 - Power supply voltage too high
EB3 - Power supply voltage too low

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!

      I have the same problem. Can’t get into service mode, it shows E00 when I try to get in service mode.

      Trying to run the Dryer (76786IH1) and is just shows “ERR” constantly. Tried reseting unplugging the cord for 30min.. nothing 🙁

      Did you get yours working?

    I have a john Lewis Heat pump tumble dryer JL TDH18 same as the video. How can the condenser matrix be cleaned out? I always clean after every use, but now after a few years the condenser matrix looks like it needs taken out and given a good clean with a hose. The recommended cleaning only gets to the first half inch of the matrix. The matrix looks as if is is blocking up and needs replacing. Surely there should be a better way or do these machines only have a few years life before needing to be replaced.

    Hi, Great video, inspired me to see if I can get AEG heat pump dryer Model T865801H Type TC09H6BHP Prod No. 916 096 749 00 up and running for my daughter who is now in need of one. Had a local repairer look at it quite some time ago when it was displaying different error codes but after paying them to investigate they just offered to take the machine off my hands which i declined. Since collecting the dryer from them it only shows E91 (ie different from original codes as I recall) in all the settings and which is not a code listed on your site. Can you shed any light on what parts may be required to rectify so I can see whether it would be economical to repair.
    Kind regards
    Andrew

    Hi on my john lewis heat pump dryer JLTDC01 I get error code E32, i know what description says but what does that mean in plain English. The water pump to drawer works fine, the compressor cooling fan works, the drum turns both directions fine.The compressor vibrates as if working but cant hear any gurgling. My issue is their is no heat.I have cleaned all filters,and the heat exchanger has been cleaned by me also/flushed out. The sensor on heat exchanger is working too.

    Any help would be great thanks.The components are exactly same as in video.
